Title: Power supply for driving ac motor
Inventor: ICHIKAWA KOUSAKU
IPC: H02P1/30
Filed: 1978-08-24
Abstract: PURPOSE: To prevent a semiconductor element from damaging due to failure of commutation in a power supply for driving an AC motor by switching frequency and power factor improving capacitors of an inverter at its frequency switching time when the inverter is temporarily stopped or the like.  
     CONSTITUTION: When a rated frequency is f 0 , an inverter 14 is operated by setting its starting frequency at f 0 /3. When a comparator circuit 17 detects the substantial  coincidence of the output signal A from a revolution detector 16 mounted as one  representative of a motor 10 to the output frequency signal B from the inverter, it  generates its output detection signal C to thereby stop the inverter 14 at time t 1 . In  the meanwhile, the set frequency of the control circuit 18 for the inverter 14 is  switched to next stage (2/3f 0 ), and a power factor improving capacitor 15 is switched to set the power factor at 0.9∼1.0 at this frequency. The inverter 14 is again  operated at time t 2  when this operation is finished to gradually raise the voltage.  Since the time duration between the times t 1  and t 2  is approx. 1 second, a motor  having large inertia does not almost decelerate at its rotation. Thus, it can prevent  abnormal occurrence at frequency switching time at the inverter.

Title: Computer
Inventor: WATANABE MASATAKA
IPC: G06F12/08
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To attain the fast processing of a computer in response to the request of a CPU by accessing a specific memory area set by a user via an auxiliary buffer almost equal to a specific memory when the specific memory area is misread. SOLUTION: A CPU 1 including an L1 cache 100 and an L2 cache 200 of a direct through system including partly the address and data of a main memory 6 are connected to a system controller 7 via a host bus 8 and also to the memory 6 via a bus 5. The controller 7 has an address part of an L2S cache area and an L2S buffer 15 which stores plural data. Then the controller 7 stores plural pairs of addresses and data which are sent out from the cache 200 in the L2S cache area where a user frequently repeats the read/write operations. Thus, it is possible to attain the fast processing by transferring the address data to the CPU 1 from the buffer 15 even when the cache 200 is misread.

Title: Balancing mechanism for cap
Inventor: SUZUKI YOUJI
IPC: G03G15/04
Filed: 1980-07-28
Abstract: PURPOSE:To provide a balancing mechanism for a cap which is of a small size and by which stable operation is obtained by incorporating the construction wherein one fulcrum is used and large frictional force is obtained. CONSTITUTION:A joint 1 is constituted of an eccentric sleeve 1b supported freely rotatably by a shaft 1a in a position deviated by (e) from a center, and a axial supportor 1c in contact with said sleeve 1b. A movable member 3 for mounting a cap 10 is coupled to the sleeve 1b by means of a pin 4, and the sleeve 1b rotates around the shaft 1a. A compression oil spring 2 is grasped by the supportor 1c and a movable member 5 for adjusting restoring force moved by the rotation of a screw 6 for adjusting restoration. Hence, adjusting the value of the torque generated by said balancing mechanism simply necessitates charnging the degree of compression of said spring 2 by rotating said screw 6 and moving said member 5.

Title: Method for packing wafer product case
Inventor: TAKASHIMA CHIKAYUKI
IPC: B65D85/86
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To maintain silicon wafers at the same cleanliness as that when the wafers are manufactured without causing pinholes in the welded sections of resin-made packing bags at the time of transporting wafer product cases by specifying the atmospheric pressures in the packing bags. SOLUTION: The atmospheric pressures in packing bags are adjusted within a range of 0.90-0.99 atm, preferably, 0.95-0.99 atm. Various kinds of resins can be used for the packing bags, but an aluminum-coated polyester which is coated with aluminum so as to prevent moisture from getting in polyester that discharges a little amount of material, can resist friction, and can be welded is preferable. After one bag containing product cases is set on a sealer machine and the inside of the bag is deaerated with a pump, the mouth of the bag is welded. Therefore, silicon wafers can be transported in clean states even when the bag is transported by air, because no pinhole occurs in the welded section and the fluctuation of humidity with time can be suppressed.

Title: Transmission belt manufacturing method
Inventor: IMADO SHINYA
IPC: B29D29/00
Filed: 1978-08-24
Abstract: PURPOSE: To obtain a transmission belt economically, by forming a cylindrical body, cutting it into a ring, with one side wider than the other so as to form a trapezoidal cross section, in such a manner that both edges of the wider side are overlapped, and thereby reducing losses.  
     CONSTITUTION: Cylindrical body 1 is made of natural rubber, synthetic rubber, or synthetic resin. This is cut into a ring in such a manner that its cross section forms a trapezoid. Both edges 2A, 2A of the broader side are overlapped when it is cut. Transmission belt 4 formed in this way is hexagonal, with both edges 2A, 2A of the broader side cut diagonally. But the cut parts have nothing to do with the transmission efficiency. By this, the shaded portion between 2B, 2B, which becomes totally wasteful, can be greatly reduced.
