Title: Variable magnification optical device
Inventor: TOKUHARA MICHIHIRO
IPC: G03B27/34
Filed: 1981-02-12
Abstract: PURPOSE:To make a variable magnification optical device compact, by turning a lens and a mirror in an angle ratio 2:1 when the light path length is corrected in accordance with magnification conversion without changing entrance and exit light paths. CONSTITUTION:When the magnification is varid, a mirror 12 is turned at theta in the directionof C with the reflection point as a fulcrum, and a lens 3 is turned at 2theta in the direction of D and is displaced in the direction of E. A mirror 13 is turned at theta in the direction of (f) and is dispalced in the direction of (g) by (x). When the length betwen entrance and exit light paths, the focal length of the lens, and the variance of the light path length for varying to a magnification beta are denoted as l, (f), and DELTA respectively, these values have relations indicated by expressions (1)-(4). In this case, a slit region of an original 6 is bent by a mirror 12' and is furthermore bent on a mirror 13' by a lens 3' and is projected onto a slit region of a photoreceptor 7 rotating in the direction of an arrow. Consequently, an entrance light path 18 and an exit light path 19 are fixed even if the magnification is varied, and thus, a two-mirror compact system is obtained.

Title: Thermosensitive recording paper
Inventor: ENMANJI KIMIE
IPC: B41M5/30
Filed: 1986-01-31
Abstract: PURPOSE:To obtain a thermosensitive recording paper preventing falsification, by using a titled paper having a resin material containing particles of a colorless dye, particles of a substance becoming acid on heating, and particles of a substance having a melting point higher than the above substance and becoming basic on heating. CONSTITUTION:When a thermosensitive recording paper is heated at and around the melting temperature of a substance becoming acid on heating, the substance becoming acid on heating melts and reacts with a colorless dye 1 to produce a color, thus forming a coloring portion 6. Furthermore, the thermosensitive recording paper is heated at and around the melting temperature of a substance becoming basic on heating, whereby the substance becoming acid on heating and the substance becoming basic on heating are melted together and neutralized, thus resulting in the condition in which the coloring of a colorless dye 1 is inhibited. This condition is maintained even if the paper is reheated, and a fixing portion 9 is formed. Benzoyl leuco methylene blue is used as the colorless dye, and p-hydroxybenzonate benzyl ester of 60-120 deg.C melting point or the like is used as the substance becoming acid on heating and diphenyl quanidine-ditrimethylphenyl guanidine of 140-200 deg.C melting point or the like is used as the substance becoming basic on heating.

Title: Forming method of thick-walled uo steel pipe
Inventor: KOUNO TAKESHI
IPC: B21D5/01
Filed: 1979-02-23
Abstract: PURPOSE: To form the blank pipe of good shape with an O press of low load by C- forming the material to be formed then U- and O-forming the same to the specific forming length and undeformed band length without allowing the end part of the material and lower die contact with each other than the contact parts of both at all times during forming.  
     CONSTITUTION: In order to obtain a steel pipe of a thick wall of not less than 19mm in particular, the material to be formed 8 of a thickness tmm is C-formed with the dies of such constitution which does not permit the contact of the material and a lower die 6 other than the end part 9 of the material to be molded 8 and the contact part 10 of the lower die from the start of forming until completion. Thereby, the short undeformed band 21 length lF is obtained under low forming load, and if the outside diameter of the steel pipe is let Dmm, the C-forming length L is made 0.05π(D-t) or more and the length lF is made D/2tan(cos -1 D/D+5) or less. When the length lF deviates from this, large peaking P occurs and when the length L satisfies the foregoing, the gap δ after the O forming is assured, resulting in the short length lF. Thereafter, the U- and O-formings are done in succession, but when the U punch shape and height are limited, the effect improves further.

Filed: 1984-02-08
Abstract: PURPOSE:To reduce a required space by folding some parts of a base, on which components are provided, into the inside, by fixing an input/output signal cable by a folding part and a fixing member through an elastic body and by arranging a power source noise filter circuit in the folding part and a U-shape formed as a base. CONSTITUTION:By folding some part of a base 6 into the inside of the device, a signal cable 7 is fixed with simple constitution, which allows a connector 8 not to remove from a magnetic disk drive 2 in the device interior due to external force, and a screw head will not be exposed to the outside. Moreover a filter circuit 5 is arranged in a U-shaped part formed by the base 6 and a folding part 61; therefore the filter circuit 5 can be sealed from the signal cable 7, which develops effects to prevent power source noises from entry. Thus, since the filter circuit 5 can be put near to the signal cable 7, each component can be arranged compactly in the device.

Title: Inspection of semiconductor device
Inventor: MATSUMOTO MICHIO
IPC: H01L21/66
Filed: 1991-02-13
Abstract: PURPOSE:To obtain a detection method for loose contact of a bonding wire of a semiconductor device, wherein, even in the case that a semiconductor chip and the bonding wire are coated with resin, detection is possible, loose contact can surely detected, if loose contact exists, even when the detection is executed by using a forward voltage, and the detection is easy. CONSTITUTION:The title method uses the fluctuation of resistance component in current-voltage characteristics. In the case of a transistor semiconductor device, two points of detection current values IF1 and IF2 are detemined. In the difference of each VF(E-F), decision reference is set, and the defective contact of a bonding wire is detected. Since the monitor of  VF(E-B) is used, it does not happen that detection is impossible on account of resin coating. Since two points of detection current values are set, detection is surely possible in the case of loose contact. Since automatic measurement is possible on account of specification setting, decision is easily enabled in a short period.

Title: Gas mixture controller of internal combustion engine
Inventor: GIYUNTAA BURAUN
IPC: F02D41/12
Filed: 1985-02-06
Abstract: The invention is directed to a mixture metering arrangement for an internal combustion engine with a digital data processor, particularly a microcomputer, the signal processing pattern of which is governed by clock pulses, and with a signal generating means which delivers analog output signals. The signal generating means is responsive to operating parameters of the internal combustion engine and is an exhaust gas sensor responsive to the air ratio Lambda. The exhaust gas sensor is used in a closed-loop control system to influence the air-fuel ratio and changes its output quantity at the air ratio of Lambda=1. In this arrangement, a correcting stage corrects the influence of a delay time (tv) connected with the clocked signal processing on the mixture formation. The delay occurs in the transmission of the change in the output of the sensor. Two methods are indicated for the mode of operation of the correcting stage by means of which a mean value shift of the quantity (FR) influencing the mixture formation is avoided and the concentration of toxic substances in the exhaust gases is minimized. Flowcharts are disclosed to realize the invention by means of a suitably programmed microcomputer.

Title: Switch device
Inventor: KYODA TATSUO
IPC: H01H25/04
Filed: 1995-02-08
Abstract: PURPOSE: To dispense with a part exclusive for stopper mechanism. CONSTITUTION: Stopper mechanisms 33 and 805 for regulating the simultaneous operation of two sets or more of switches of four sets of switches when a push plate 3 is thoroughly pushed or obliquely pushed are provided on the edge of a through-hole 33 in the center of the push plate 3 and the switching nob 8 of a two-way switch. Consequently, the stopper 33 on the push plate 3 side comes into contact with the stopper 805 on the switching nob 8 side to regulate the simultaneous operation of two sets or more of switches of four sets of switches when the push plate 3 is thoroughly pushed or obliquely pushed. Since the stopper mechanism is constituted by utilizing the edge of the through- hole 33 of the push plate 3 and the switching nob 8, thus, no part exclusive for stopper mechanism is required.
