Title: Semiconductor wafer holding device
Inventor: SATO TOYOHIKO
IPC: H01L21/673
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor wafer, which can reduce the cracking of semiconductor wafers and can hold semiconductor wafers with high accuracy. SOLUTION: Since plate-like members 17a and 17b are attached to the internal surfaces of bellows-like sidewalls of a semiconductor wafer holding device, the plate-like members 17a and 17b nearly in parallel come into contact with semiconductor wafers 13, even if the sidewalls 11a and 11b are folded up. Consequently, stresses are equally applied to both sides of the contacting sections between the wafers 13 and members 17 and 17b and no large moment occurs around the full peripheries of the wafers 13, and in principle, the wafers 13 will not crack. Since a plug 18 for enclosing and discharging a gas in and from air chambers 10a, 10b, and 15a is provided to the lid section 15 of the device, and the bottom section 16 of the device is made solid, high wafer-holding accuracy can be realized.

Title: Uninterruptible ac power supply apparatus
Inventor: KONISHI DAISUKE
IPC: H02J9/06
Filed: 1994-11-25
Abstract: PURPOSE: To obtain a low cost and stable control power supply by a method wherein the input of a DC/DC converter for the control power supply is supplied from a commercial AC power supply and an AC output through diodes. CONSTITUTION: Both a commercial AC power supply 1 and an AC output 2 are of single phase. The respective one side lines of them are connected to each other inside and hence have the same potential. This common line, the other line of the commercial power supply 1 and the other line of the AC output 2 are connected to three AC input points of a diode bridge for three-phase full-wave rectification. Once an AC uninterrupted power supply apparatus starts operation and is turned into a normal operation, the higher one of the input voltage and the output voltage of the apparatus is automatically supplied to the input of a DC/DC converter and, when the commercial power supply is interrupted, the power is continuously supplied from the AC output 2 through diodes 20.  Further, if a power converter is failed or the supply capability of the apparatus is exceeded, an inverter switch 11 is forcibly cut off and a direct transmission switch 10 is turned on. Therefore, a low cost control power supply with a stable voltage can be obtained.

Title: Self-actuating nuclear reactor shut-off mechanism
Inventor: ARASHIDA GENJI
IPC: G21C9/02
Filed: 1987-12-14
Abstract: PURPOSE:To prevent a malfunction of a mechanism, by providing a plurality of grooves through which a reactor core coolant flows, at peripheries of an armature or an electromagnet or both, to get a large difference of an electromagnetic coercive force between a normal operating condition and an abnormal one. CONSTITUTION:An armature 4 of a nuclear reactor shut-off mechanism is composed of a magnetic material having its Curie point to be the same temperature to which a sodium flow temperature rises at an abnormal operating condition, and with a phenomena which a sodium temperature at an outlet of a fuel assembly 9 in the abnormal operating condition rises and the temperature of the armature 4 reaches to the Curie point, a magnetic attraction between the armature and an electromagnet 8 is weakened. Therewith, the armature 4 is separated from the electromagnet 8 and a control rod 3 falls into a reactor core. In case that numerous grooves are provided at peripheries of not only the armature 4 but also a magnetic core 33 of the electromagnet 8, the sodium 10 touches the whole part where lines of magnetic force 17 run in the armature 4. Therefore, a thermal transfer to the armature 4 is improved and a difference in electromagnetic coercive force between a standard rate operation and an abnormal condition can be set with rather large amount of value and therewith a possibility of a malfunction is much more lessened.

Title: Pneumatic bias tire
Inventor: TANAKA TSUTOMU
IPC: B60C9/06
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To prevent a tire-deformation failure at the time of a manufacture through a year. SOLUTION: It can be prevented that a cord of a first carcass up ply 20 is heat-shrunk after completion of a post cure inflation step by employing a material having a higher heat-shrinkage beginning temperature than a cord temperature at the time of completion of the post cure inflation for the cord of the first carcass up ply 20. Since the cord of the first carcass up ply 20 has a heat-shrinkage coefficient within a range of 40-75% of that of a cord of a third carcass up ply 24, the shrinkage of the cord of the third carcass up ply 24 is larger than that of the cord of the first carcass up ply 20. Therefore a stress caused by a shrinkage of a whole tire can be relieved and the shrinkage of the whole tire can be uniformly small.

Title: Auxiliary plate for taking out facial tissue
Inventor: HIRANO SHIGERU
IPC: B65D83/08
Filed: 1989-12-07
Abstract: PURPOSE:To prevent a facial tissue pull-out portion exhibited out of a take-out port from dropping inside as well as permit the tissue to be easily taken out even if the pull-out portion has dropped by causing the facial tissue pull-out portion exhibited out of the take-out port to stand. CONSTITUTION:Although a facial tissue can be easily taken out since a tissue pull-out portion 3 is out of a take-out port 2 at an initial stage of use, the tissue pull-out portion 3 drops inside from the take-out port 2 as the number of tissues 8 decreases. An auxiliary plate 5 made of paper, wood, plastic, metal, etc. having an opening 6 with a center part wide and both ends narrow along a longitudinal axis of the rectangular auxiliary plate 5 is placed. By pulling out the pull-out portion 3 through the opening 6, a foot 4 of the tissue pull-out portion 3 is kept standing since it is supported by the opening 6 of the auxiliary plate 5 together with a foot 7 of a next pull-out portion. Even if the pull-out portion 3 of the tissue drops inside the take-out port 2, the pull-out portion 3 is kept standing from its foot 4 so that it can be taken out from the take-out port 2. The opening 6 of the auxiliary plate 5 may be either elliptic or rhombic.

Title: Barrier opening/closing mechanism
Inventor: NOGUCHI YUKIO
IPC: G03B11/04
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a barrier opening/closing mechanism capable of surely opening/closing a lens barrier even in the case a lens barrel is somewhat extended and withdrawn by providing a lever to convert force in an optical axis direction into force in the circumferential direction of an optical axis. SOLUTION: By extending and withdrawing the lens barrel 1, a pressing member 8 turns the lever 9. By such turning of the lever 9, the pressing force of the member 8 is naturally converted into the force in the circumferential direction centering the optical axis 10 and efficiently transmitted to an opening/ closing driving ring 24. Therefore, even in the case the moving distance of the lens barrel 1 from a wide end to a collapsing position is short, the ring 24 is smoothly moved and the lens barrier 22 is surely opened/closed.

Title: Automatic dialing device for automobile telephone
Inventor: KATO TATSUNORI
IPC: H04B7/26
Filed: 1989-12-06
Abstract: PURPOSE:To make it unnecessary to turn user's eyes upon the operating part of an automobile telephone by confirming and sending the telephone number of an objective remote party by a voice stored beforehand thorugh the operation of a selector switch and a hook switch. CONSTITUTION:In the case of originating a call, the user pushes the selector switch 15, and selects the objective telephone number. The automatic dialling device is constituted so that a selecting means 16 selects the voice stored in a voice storage means 12 and the telephone number corresponding to it according to the number of times of pressing the selector switch 15. Accordingly, since the selected voice is sounded from a speaker 14 by a voice reading and sounding means 13, the user can confirm whether the objective remote party is selected or not by hearing the voice. Then, when the voice showing the telephone number of the objective remote party is heard, by pushing the hook switch 18, a telephone number reading and calling means 19 reads out the selected telephone number from a telephone number storage means 17, and originates the call. Thus, the user need not turn his eyes upon the operating part of the telephone.

Title: Substrate placement device and vacuum process device
Inventor: FUWA KO
IPC: H01L21/68
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a substrate placement device with less dust and high thermal conductivity. SOLUTION: Related to a substrate placement device 11 provided on a bottom wall side of a vacuum vessel 1, an elastic member 18 is fitted inside the recessed part on the surface of a dielectric body 12. The surface of elastic member 18 is higher than the surface of dielectric body 12, and when, with a substrate 7 placed on the elastic member 18, the electrodes 13 and 14 provided inside the dielectric body 12 are applied with a voltage, an electrostatic attraction force is applied to the substrate so that the elastic member 18 so compressed that the rear surface of the substrate 7 contacts the surface of the dielectric body 12. Since the contact area to the elastic member 18 is large even when the substrate 7 is thermal-expanded, less dust is caused.  Further, since the rear surface of the substrate 7 is forced to tightly contact the surface of the elastic member 18 under the restoring force of the elastic member 18, a thermal conductivity is high.

Title: Polarizing film and production thereof
Inventor: NAGAO MASAHIRO
IPC: C08F16/06
Filed: 1989-12-05
Abstract: PURPOSE:To obtain the polarizing film of high durability which is excellent in optical characteristics, such as degree of polarization and permeability and is improved in humid heat resistance and best resistance, by using a uniaxially stretched film consisting of a specific polyvinyl alcohol (PVA) polymer as a base material. CONSTITUTION:The uniaxially stretched film consisting of the PVA polymer having <=1.5mol% coupling quantity of 1, 2 glycol is used as the base material. More preferably, the coupling quantity is confined to <=1.2mol%, further preferably <=1.0mol%. More preferable results are obtd. for the purpose of improving the water resistance, heat resistance, durability and optical characteristics of the polarizing film as the coupling quantity of the 1, 2 glycol of the PVA polymer is smaller. The production of the PVA polymer is difficult if the coupling quantity of the 1, 2 glycol is too small and, therefore, approximately >=0.5% is adequate as the coupling quantity of the 1, 2 glycol. The polarizing film having the higher strength, water resistance and heat resistance than heretofore is obtd. in this way.
