Abstract: PROBLEM TO BE SOLVED: To improve the current collecting property of a polarizable sheet electrode in the thickness direction, by constituting joining means of burr-like locking pieces formed by thrusting a caulking needle into electrode foil for collecting current. SOLUTION: A polarizable sheet electrode 2 and each electrode foil 3 for collecting current are integrally joined to each other by thrusting a caulking needle 4 into the electrode 2 and foil 3. In other words, holes 31 are formed through the electrode foil 3 and, at the same time, burr-like locking pieces 32 are formed around the holes 31 by thrusting a caulking needle 4 in the foil 3. Therefore, when the caulking needle 4 is thrust into the electrode 2 and foil 3 while the electrode and foil 3 are laminated upon another, the burr-like locking pieces 32 get into the foil 3 and work as joining means to integrally join the electrode 3 to the foil 3. It is preferable to adjust the number of thrustings of the needle 4 per unit area such that the total area of the thrus holes as <=1/2 of the unit area.

Title: Manufacture of semiconductor laser
Inventor: KAMEI HIDENORI
IPC: H01S5/00
Filed: 1992-05-13
Abstract: PURPOSE:To improve mass productivity and yield rate of the manufacture by forming a plurality of laser bars or chips by cutting out laser units formed in a laser wafer. CONSTITUTION:After first electrodes 12 are installed in parallel on the upper basal plane of a laser wafer 10, a mask layer 13 is formed on them. Then the mask layer 13 is removed except its part on the electrodes 12 to form strip-shaped mask layers 13a. Next, etching is performed deeply enough to make sections of an active layer 11 be exposed to form rectangular grooves 14. Under this condition, after a dielectric film 15 with a specific thickness is simultaneously formed on the whole surface of the laser wafer, the remaining parts of the mask layer 13 are peeled off together with the dielectric film 15 on them. By this process a dilectric film 15a is formed on the side part and the bottom part of each rectangular groove 14. At this time a second electrode 16 is formed. A plurality of laser bars are formed by vertically cutting up the first electrode 12 and the bottom part of the rectangular groove 14 approximately along their center lines in the direction perpendicular to the direction of light.

Inventor: ATAKE YASUYUKI
IPC: G05D3/00
Filed: 1990-05-14
Abstract: PURPOSE:To detect runaway of servo motor and insufficient positioning control of a machine to be controlled by producing a position detection pulse corresponding to the rotational amount of servo shaft and controlling the servo motor according to the difference between an accumulated amount of target pulse and a current accumulated amount of position detection pulse. CONSTITUTION:Upon start of operational control of a servo motor 1, a CPU 11 presets the time of comparison between a difference and an allowable amount in a comparison counter 15. Subsequently, the CPU 11 sets a predetermined address in an address counter 16 and makes a judgment whether 'the difference > the allowable amount'. Upon occurrence of abnormality such as runaway of the servo motor 1 or malfunction, the difference exceeds the allowable amount. Consequently, the CPU 11 outputs an abnormality detection signal AS through a bus line 19 and an I/O interface 14. Upon receiving the abnormality detection signal AS, a driving circuit 3 interrupts power supply to the servo motor 1.

IPC: G01S5/30
Filed: 1991-05-27
Abstract: PURPOSE:To measure in a short time the positions of all transponders even if there are a plurality of them by transmitting call signals to several transponders in the order near a device, on the basis of the position relation detected. CONSTITUTION:Call signals directed to transponders 71 to 7n from a transceiver 2 are in order transmitted. The transponders 71 to 7n transmits response signals in answer to the call signals directed to themselves. A receiving element 3 to receive their response signals outputs the phase difference signals corresponding to the incident angles of sound waves according to a super short base line method. On the basis of these phase difference signals, a CPU 4 decides the directions and the distances of several transponders, and determines the position relation with these transponders. Further, the CPU 4 makes calls with a certain time lag from the order near itself on the basis of those position relation and receives their response signals in order with the time lags and the distance differences of calls. Position detecting processes or operations are carried out between those receiving, and the effective position measurement of a plurality of transponders can be made.

Title: Fuel injection pump
Inventor: HIRANUMA SATOSHI
IPC: F02M59/26
Filed: 1994-04-22
Abstract: PURPOSE:To prevent the occurrence of cavitation and erosion, and improve fuel charging efficiency by providing a negative pressure prevention passage with a nonreturn valve allowing only a fuel flow from a main fuel passage to a pressure chamber. CONSTITUTION:During engine operation, a plunger 16 in a pump element 10 rises and after the upper edge of the plunger 16 passes the upper end of a feed hole 24, fuel in a pressure chamber 20 is pressurized and a delivery valve 18 is thereby opened to feed fuel to a fuel injection nozzle 36 under pressure. In this case, a check valve 46 is close. Then, the plunger 16 enters downward stroke, and is displaced to a position slightly lower than the upper dead center, thereby temporarily interrupting communication between the chamber 20 and a fuel chamber 22. Consequently, when negative pressure tends to be generated in the pressure chamber 20, the force of a weak spring 50 is overcome by differential pressure between fuel pressure in a main fuel passage and fuel pressure in the chamber 20 to open the check valve 46. As a result, fuel is fed to the chamber 20 from an oil gallery 26 and the occurrence of large negative pressure is properly prevented.
