Title: Selective display circuit of switches
Inventor: YOSHIZAKI MAMORU
IPC: H01H9/16
Filed: 1978-01-10
Abstract: PURPOSE: To simplify electrical connection constitution and facilitate its expansion as well by so arranging the circuit that when one out of (n) push-buttons is selected and depressed the corresponding code is generated and the corresponding lamp displays.  
     CONSTITUTION: Clock ϕ 1 causes the output of a decoder 5 to reiterate L cyclically to (a)-(b)-(c)-(d)-(b). Here, when a switch PBS 2 is depressed immediately before the output (c) becomes L, a lamp driver LD is energized and the output becomes L which then enters an inverter 7 via the switch PBS 2. This applies H to the K input of an FF 1, then the FF 1 inverts upon entering of the negative pulse of the clock (A), thus its Q output becomes L and its -Q output becomes H. According to this, a relay driver DR is energized to turn ON the contact (r) of a relay R, thereby causing a lamp LP 2 to light. Along with this, the (B) input of a counter 4 becomes normally H, thus stopping the stepping. The (c) input of the decoder 5 is held at normally L and its output (C) maintains L. This state is released by depressing the switch PBS.

Title: Solar battery
Inventor: ITOU YOSHIO
IPC: H01L31/06
Filed: 1982-01-11
Abstract: PURPOSE:To provide the highly efficient solar battery, by expediting the diffusion speed of optically excited electrons and holes, thereby reducing recombination probability. CONSTITUTION:The band structure of the solar battery comprises a conductor 1, a valence band 2, and a Fermi level 3. Added impurities for obtaining a P type have a concentration gradient from a P region to an N region, and the concentration gradually becomes low. At the center of a P-N junction, the concentration of the added material is almost zero. Then, impurities for obtaining an N type are added so as to obtain high concentration gradually, and the N region is formed. In the P-N junction solar battery formed in this way, the impurity concentration becomes 10<18>-10<19>pieces/cc only at the region, which is a part of the other end of the junction of the P region and the N region. The concentration in the region of the most other part becomes less than 10<18> pieces/cc.

Title: Vibration-proof device of die cushion
Inventor: YOKOTA FUMIKI
IPC: B30B15/00
Filed: 1981-01-09
Abstract: PURPOSE: To prevent crashing of the stopper at the end of the rod and to restrain vibrations and noises during the course of cushion press, by installing a dumper mechanism to the rod having the cushion ram at the end part and by restraining abrupt ascents of the ram.  
     CONSTITUTION: When a pressing is completed, the inner pressure of chambers 17 and 16 is increased because a die is raised. Because of the increase of the inner pressure, an upward force is given to the 1st cushion ram 11 of a die cushion 10, and a stopper 20 at the end of a piston rod 14 is lifted. Then, the air in a cylinder 24 is compressed, and the air flows out while it is controlled by an orifice 25. Therefore, abrupt ascents of the stopper is restrained and, since the stopper 20 does not crash against a stopper screw 21, occurrences of vibrations and noises are prevented.

Abstract: PURPOSE:To prevent cracking of a side end of a locking hole by integrally providing a pawl at least at a center of one surface of a protrusion formed at right and left sides of a partition for partitioning an inner box, and locking one side of the pawl to a locking hole of the box. CONSTITUTION:Protrusions 5 are provided at right and left sides of a partition 4, and a pawl 6 is integrally formed with a center of an upper surface of the protrusion 5. On the other hand, a lateral recess 7 for supporting the side of the partition 4 and a locking hole 8 having a long lateral side to pass the protrusion 5 of the partition 4 side are formed at the side of the box 3. The partition 4 is coupled to the box 2 and one side of the pawl 6 formed on the upper surface of the protrusion 5 is locked to an edge of the hole 8. Thus, when the protrusion 5 is passed to the hole 8, a force for a peripheral edge of the hole 8 is generated only at a center without applying a forcible strength of the protrusion 5 to the side end of the hole 8, and dispersed. Thus, a crack at the side of the hole 8 can be eliminated.

Title: Demagnetization of steel material
Inventor: OIKAWA YOSHIROU
IPC: H01F13/00
Filed: 1983-01-12
Abstract: PURPOSE:To obtain a secure demagnetizing effect without increasing the processing time by a method wherein a steel material is held between yoke-type magnetic poles to form a magnetic circuit and a DC commutated attenuating current is applied to a coil wound on the yoke and the frequency of commutation is increased after an intermediate time of the process.

Title: Synthetic resin molding machine
Inventor: ISHIDA TAKESHI
IPC: B29L11/00
Filed: 1984-01-09
Abstract: PURPOSE:To provide a molding machine capable of producing a concave lens or the like free from any weld line, by injecting a melted synthetic resin raw material first into part of a mold where the melted resin will otherwise be introduced rather late and thinner part will be formed, and then into other part where thicker part will be formed. CONSTITUTION:Since injection pressure is not exerted to a mold section 8 before a synthetic resin is injected thereinto, the inner end of an injection slider 4 is positioned at the central section of the mold section 8 by the energizing force of a coil spring 5. In this state, a melted resin raw material is injected from a gate 7 by a raw material injection apparatus. Then the injection slider 4 is automatically retreated by the injection pressure against the energizing force of the coil spring 5, and when the inner end thereof has reached the circumferential surface of the mold section 8, the retreat stops. At this point, the melted resin raw material fills completely the mold section 8, and the raw material starts to solidify uniformly. After a certain period of time, a top force 3a is removed, and the solidified desired concave lens free from any weld line is taken out.

IPC: H04M3/42
Filed: 1985-01-10
Abstract: PURPOSE:To well manage the message identification number by updating autonomously the serial number of the input given from the terminal at the starting time of the communication, but thereafter, the inputted serial number on the exchange side for the following messages. CONSTITUTION:Receiving the first message from any terminal, a store and forward switching equipment takes the serial-number-management recording number, and writes 'occupied' in the vacant/occupied displaying area in the serial-number management recording, and sets the serial-number-management number. The equipment also receives the destination of communication, and performs the reception recording of the message. At this point of time, the voice store and forward switching equipment quests if the allocation of the serial number is done on the terminal or on its own side. If the allocation on the terminal side is requested, it is performed by the operator at the terminal. But if it is requested on the equipment side, the switching equipment informs the terminal of the content of the terminal-allocated serial number register 14 making it the serial number.

At this time, when an O2 partial pressure is set to a proper value, the crystal orientation of an MgO film can be oriented to (111), and the coercive force of the Co/Py layer manufactured on MgO can be increased. Thereby, the MgO is transparent and becomes an enhancement film, and the Co/Pt layer can be manufactured under a low Ar partial pressure and becomes a film in which a void is small. As a result, the large signal intensity and the small noise of the title element can be realized simultaneously.
