Title: Electrodynamic flow control valve
Inventor: OOMI TAKEHARU
IPC: F16K31/70
Filed: 1979-11-02
Abstract: PURPOSE: To prevent freezing of an electrodynamic flow control valve, by building  in a bimetal which minutely oscillates the valve mechanism with its repeated inverting action at around the freezing point.  
     CONSTITUTION: The external circumference of a bimetal 25 is held between a  retainer 26 and two electric contacts 27, 28. As temperature drops below a preset  level, the bimetal 25 is deformed and its external circumference comes in contact  with the contacts 27, 28. Since the bimetal has its terminals 29, 30 connected with  a heating wire 31 made of nichrome foil, the heating wire 31 gets heated when the bimetal 25 is distorted and the contacts 28, 27 touch the terminals 29, 30 respectively, which causes the bimetal 25 get heated to return to its original state. The bimetal 25 is designed to repeat this action in accordance with the thermal fluctuation at around the preset temperature. A bobbin 9 pressed by springs 12, 13 to the bimetal 25 also follows the minute action of the bimetal 25 together with a slide valve 20.

Title: Monitoring method for body in periodic motion
Inventor: TAKEYASU KAZUHIRO
IPC: G01M13/00
Filed: 1981-09-08
Abstract: PURPOSE:To monitor a body in periodic motion without reference to equipment size, a load, etc., by comparing the dispersive normalized value of the even- numbered moment of the probability density function of oscillation data with the normal logical value of the body in periodic motion, and thus detecting a fault. CONSTITUTION:The oscillation of reduction gears 1 for a body in periodic motion is detected by an oscillation detector 4 and sampled at specified intervals by a sampling circuit 5, whose output is A/D-converted and then stored in a storage device 6. On the basis of the storage contents, a computing device 7 performs arithmetic according to equalitiesIand II to calculate the dispersive normalized value K of the even-numbered moment of the probability density function of the oscillation data which corresponds to the extent of a normal distribution. Then, a comparing circuit 9 compares said calculated value with a logical dispersive normalized value K as a constant, such as three, of the body in periodic motion stored in a memory 8 and when their difference is great, a decision on the occurrence of a fault is made to operate an alarm device 10, etc. This constitution monitors the body in periodic motion without reference to the equipment size, load, etc. Further, P(x):x is the probability density function.

Abstract: PURPOSE:To prevent a short circuit between a gate electrode and a drain region by forming the gate electrode only on a gate oxide film. CONSTITUTION:A gate electrode 7 is structured in such a way that it is formed only on a flat gate oxide film 6; the gate electrode 7 is not formed in a boundary part, between a thick field oxide film 11 and the thin gate oxide film 6, where a pinhole and a defect of the oxide film are apt to cause; accordingly, an inconvenient situation such as a short circuit between the gate electrode 7 and silicon is not caused. Thereby, it is possible to prevent a short circuit between the gate electrode 6 and a drain region 3.

Title: Binding machine
Inventor: TANGE YOSHIAKI
IPC: B65B27/00
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a binding machine in which a working efficiency can be improved. SOLUTION: A position of a supporting plate 70 is set in compliance with a diameter of a bound member M. When a rotary cam 50 is rotated, a pivoting piece 60 is pushed out and driven to cause a guidance arm 32 to be turned in a counter-clockwise direction only by a predetermined amount, resulting in that a wire H fed out of a feeding-out groove 31 is bound around the bound member M while being guided to the bound member M inserted into a recess 21 by an abutting surface and so even if the bound member having a smaller diameter than an opening width of the recess 21 is to be bound, it is possible to perform a binding operation in correspondence to this diameter, it is not necessary to select the binding machine and further it becomes possible to improve a working efficiency.

Title: Bonding of semiconductor device
Inventor: IINO KAZUHIRO
IPC: H01L21/60
Filed: 1988-06-08
Abstract: PURPOSE:To prevent the deformation of a lead frame due to the thermal expansion and the oxidation of the frame surface from occurring by a method wherein a metallic wire is brought into contact with an outer leading electrode and the contact part irradiated with laser is cooled down after melting and mixing processes to be brought into an ohmic contact. CONSTITUTION:The end of a copper wire 1 held by a clamper 4 is brought into contact with an outer leading-out electrode 3 to irradiate the contact part with laser 5. At this time, if the irradiating angle exceeds the surface of the electrode 3, the electrode 3 is broken down by the laser 5 to make the connection defective. On the other hand, if the laser power is excessive, the copper wire 1 and the electrodes 3 may be evaporated. Consequently, the laser 5 is selectively irradiated at high condensing ratio not to irradiate a semiconductor element 2 excluding the outer leading-out electrode 3. Through these procedures, the deformation of a lead frame due to thermal expansion and the oxidation of the frame surface can be reduced.

CONSTITUTION:A bearing device is constituted such that a metallic saddle 11 is seated to be placed on the outer ring of a rolling bearing fitted to an axle through a coating film 12 of insulating high molecular material. In this case, to manufacture said coating film 12, first the saddle 11 is heated to a temperature above the melting point of powders of insulating high molecular material, and the powders of insulating high molecular material are applied to the seating surface, that is, the internal peripheral surface of the saddle, while said powders are melted by heat of the saddle 11, thus the internal peripheral surface of the saddle 11 is painted with a coating film layer of insulating high molecular material. Next, a forming mold 13 is pressed to the coating film layer before its temperature is decreased to a level below the melting point of said powders, and the coating film layer is finished to a required shape. Then the coating film layer is hardened by firing treatment at a temperature above the melting point of the insulating high molecular material, thus the coating film 12 is obtained.

Filed: 1994-06-24
Abstract: PURPOSE:To dispense with the forming of a terminator out of metal or by mold, and to reduce the cost, by connecting a termination resistance internally to an electron apparatus at the termination, automatically. CONSTITUTION:The A connector for in-line connection has three pins, and its A and B terminals are connected to signal lines 22 and 23 at the inside respectively. A GND terminal is earthed through an internal signal line 24 and a resistance 25 for standard potential. The B connector has also three pins in the same manner. Since a cable is not connected to the B connector at the inner side of an electron apparatus group connected in-line, a microswitch 28 is closed, and a termination resistance 29 is connected automatically. In the electron apparatuses other than the electron apparatuses at both sides, of the electron apparatus group connected in-line, the cable is connected to the B connector, the switch 28 is opened, and the resistance is made in the released condition. As a result, the laying work of the electron apparatus through a communication wire is simplified.
