Title: Semiconductor device
Inventor: KONDOU HISAO
IPC: H01L21/331
Filed: 1980-07-10
Abstract: PURPOSE:To prevent the concentration of a collector current in a wide range by maximizing the impurity concentration at the center of a shorter side of an emitter stripe. CONSTITUTION:Impruities are thermally diffused n times employing a stripe mask sequentially in such a manner that the longer side thereof is constant while the shorter side thereof is set at y1<y2<...<yn so that an emitter 11 is formed with a such a distribution that the concentration reduces gradually to the end of the shorter side from its maximum in the center thereof. Here, the injection efficiency in the emitter-base junction interface becomes so less at the end rim + or -L of the shorter side of the emitter that the collector current IC fails to concentrate on the end rim thereof, hence showing an even distribution of the concentration. This eliminates a local heating thereby expanding the range of safe operation. In addition, there is no sudden drop in hFE in a large range of IC.

Title: Recording power detecting system for optical disk device
Inventor: MIZOGUCHI YASUMITSU
IPC: G11B7/125
Filed: 1985-05-07
Abstract: PURPOSE:To perform with a high accuracy a detection of a variation of a recording power caused by deterioration of a characteristic, by a simple circuit, by generating the power of an information recording time by driving a semiconductor laser like a direct current, in a state that an optical head has stopped at other position than a recording area of an optical disk. CONSTITUTION:In case of detecting a recording power of a laser diode 4, first of all, a state of 'check mode' is set by turning on a power source. Subsequently, a transistor 23 becomes an on-state and the laser diode 4 generates a DC power. In this state, the recording power is generated by the laser diode 4, and it is detected by a monitor diode 5. In this case, when the recording power is generated pulsatively, it is difficult to execute monitoring, therefore, a transistor 26 is turned on by a LASER OK signal 66 for showing that a laser has been stabilized, and the recording power is generated like a direct current. Whether the recording power is too large or too small is checked by setting an optical head 3 to the outside of a range of a recording film 2, detecting the recording power of the laser diode 4, which has been generated like a direct current, and comparing it with a reference voltage.

Abstract: PURPOSE:To distribute a remaining number in short time in auction for remain, and to shorten auction processing time so as to speed up an auction processing. CONSTITUTION:A buyer generates a proposal signal by depressing a proposal key B in a proposal machine K. On the other hand, the cost of a listed article is displayed on a bulletin board D so as to raise cost in an auction operation device S. When the total proposal number which a total proposal number calculation means 50C calculates becomes one while cost is raised, a cost stop means 50E stops the rise of cost and one buyer transmitting the proposal signal which a proposal detection means 50 A detects is considered to bid the listed articles for a purchased number which the buyer designates so as to be processed. When there is the remaining number, a remaining number bidding display means 50I displays one buyer who is stored in a transmission absence order storage means 50H and who is slow in setting the transmission of the proposal signal from presence to absence on the buyer display part 75 of the bulletin board D by considering him to be a person who bids the listed articles for the purchased number which the buyer designates. The remaining number of the listed articles is bidding-processed for the buyer.

Filed: 1981-06-19
Abstract: PURPOSE: To properly detect the exchange period of ion-exchange resin, by applying high-frequency voltage to water, to be softened, at the upperstream point of an ion-exchange filter and at its downstream point apart in a fixed distance from the upperstream point through two different kinds of electrodes located inside a vessel.  
     CONSTITUTION: When crude water is fed through an inflow pipe 3 and a net- shaped filter 13 into the filter vessel 2 of a hard water softener 1, the crude water is fed from the net-shaped filter 13 through a drain pipe 4 to a faucet or the like under the condition that the crude water is softened by ion-exchange resin 12 in the filter vessel 2. Under this water-flowing condition, the water flowing through the filter vessel 2 and the resin are handled as electrolytes, and the change of electric resistance generated by the conversion of the resin from a type-Na into a type-Ca is utilized as the difference of electric resistance to be generated between two couples of electrodes comprising reference electrodes 7 and indicating electrodes 8 in the resin-water system. The resistance difference is inputted into a detector 11 through an electric wire 10 connected to each of the electrodes 7, 8.

IPC: B07C5/342
Filed: 1994-04-07
Abstract: PURPOSE:To improve the collecting accuracy for crushed scraps containing a material to be collected by judging whether a collection is suitable or not from the ratio of whether the scraps are of the same color as that of the material inputted preliminarily or from the ratio of the resembling color occupying a reference area. CONSTITUTION:Crushed scraps 1 are fed into a part feeder 3a and arranged while being moved around the periphery of a bowl 3c and fed in a row through a straight transfer line 3d.

Title: Manufacture of thermosetting resin cast molding
Inventor: HOSHINO SHIROU
IPC: B29C39/02
Filed: 1984-05-15
Abstract: PURPOSE:To prevent resin sink and internal clearance due to hardening and shrinkage of thermosetting resin from occurring by a method wherein after the completion of resin injection, it is cooled in that state, and complementarily filling molten resin into the gap generated thereby before heating and hardening begin. CONSTITUTION:The thermosetting resin 4 heated in a liquid state is cast from the upper opening 8 connected with the injecting hopper 2 into the closed type or the pressure mold type 1. After resin is injected and before heating and hardening begin the mold 1 is cooled in such a state as it is filled with resin. A clearance equivalent to resin volume to be reduced by the difference of thermal expansion between the mold 1 and the resin 4 appears on the top of the liquid resin 4 in the mold 1, but since molten resin is supplemented from the upper opening 8 into this clearance, the mold 1 can continue to be filled fully with resin 4 even after cooling. Then the resin is heated and hardened with the upper opening 8 being blocked by the blind plug 5.

Title: Discharge triggering method of sputtering device
Inventor: MASHIRO KAZUHIKO
IPC: H01L21/3065
Filed: 1983-05-31
Abstract: PURPOSE:To maintain continuously stable discharge and to improve quality and yield by disposing a high voltage power source for discharge triggering having the output impedance and voltage higher than an electric power source to be used exclusively for sputtering in parallel with said power source. CONSTITUTION:Electric power is supplied from an electric power source 2 to be used exclusively for main sputtering through a diode 4 to an electrode 7 in a sputtering device. A power source 1 for triggering having the voltage higher than the voltage of the power source 2 and the voltage higher than the discharge start voltage of the electrode 7 is provided in parallel with the power source 2 through a high resistance 5 and a diode 3. When a normal sputtering discharge is stopped by a certain cause, the potential of the electrode 7 rises instantaneously to the potential of the power source 1. The discharge triggered by the high voltage is immediately started to restore the original equil. state and the normal and stable discharge is thus maintained.
