Title: Microprocessor
Inventor: YAMADA KATSUHIKO
IPC: G06F12/06
Filed: 1989-11-17
Abstract: PURPOSE:To improve the processing speed of a microprocessor by executing parallel processing at a microprogram control part and a memory access part. CONSTITUTION:When a memory access part 18 uses a bus 12 and a processing such as calculation, etc., can be executed without using the bus 12, a microprogram control part 16 executes this processing and afterwards outputs a bus check signal. When a memory access command is received, the memory access part 18 outputs a wait signal in order to avoid bus collision. However, this wait signal is not supplied to the microprogram control part 16 until the bus check signal is outputted form the microprogram control part 16 and the microprogram control part 16 is set in an operatable state. Accordingly, the parallel processings can be executed at the microprogram control part 16 and the memory access part 18. Thus, the processing speed of the microprocessor is improved.

Title: Wideband radiowave absorber
Inventor: KUDO TOSHIO
IPC: H05K9/00
Filed: 1993-11-30
Abstract: PURPOSE:To obtain a thin wideband radiowave absorber, by bonding a mat-like fiber aggregate wherein a magnetic powder is stuck on fibers directly or indirectly to a sintered magnetic substance tile. CONSTITUTION:A wideband radiowave absorber D is so created that a mat-like fiber aggregate 3 wherein a magnetic powder 5 is stuck on fibers 6 is bonded to a tile 2, e.g. a sintered magnetic substance tile 2 by a bonding agent, e.g. an epoxide based, isocyanate based, cyanoacrylate based bonding agent or the like. Especially, the epoxide based bonding agent is preferred because the irregular surface of the mat-like fiber aggregate 3 can be well bonded to the tile 2 with this agent and the bonded part can be stabilized for a long time. Since according to this configuration, the mat-like fiber aggregate including magnetic-powder-stuck fibers is formed on the sintered magnetic substance tile, the thickness of the whole of the radiowave absorber can be made small, e.g. to be about 60mm, in comparison with a conventional pyramid type or pyramid-single layer type composite radiowave absorber.

Title: Magnetic recording and reproducing device
Inventor: HASHIGUCHI YASUHIRO
IPC: G11B15/61
Filed: 1994-12-05
Abstract: PURPOSE: To prevent deformation of a cylinder without being influenced by accuracy in the vicinity of a cylinder mounting surface of a cylinder base and to secure the linearity of a cylinder lead without increasing the cost by making rigidity in the vicinity of a cylinder screw-fixing part of the cylinder base small than rigidity of the screw-fixing part of the cylinder. CONSTITUTION: A part 25h is provided in the vicinity of the mounting surface of the cylinder 4 of the cylinder base 25 to be smaller in wall thickness than the other part. Thus, when the cylinder mounting surface 25a of the cylinder base 25 does not match with a flat surface of the screw-fixing part of the cylinder 4 due to poor accuracy of the cylinder base 25 or defective flatness of a chassis base, the part 25h where the wall thickness of the cylinder base 25 becomes small is deformed, but the cylinder 4 is not deformed so that the linearity of the cylinder lead 4a can be secured.  Consequently, in the case of nonmatching between the cylinder mounting surface 25a and the flat surface of the screw-fixing part of the cylinder 4, it is not necessary to use particular screws with springs for the cylinder fitting screws 26 like the conventional method, and no additional machine work is required either, thus reducing the cost.

Title: Speed change stage controller for automatic transmission
Inventor: TOKORO SETSUO
IPC: F16H61/04
Filed: 1989-11-20
Abstract: PURPOSE:To reduce the number of programs by dividing a plurality of speed change stages to a low speed stage group and a high speed stage group and determining the aimed speed change stage by carrying out the fuzzy estimation only in the case when the standard speed change stage obtained from a speed change map which is constituted of the car speed-engine load belongs to the high speed stage group. CONSTITUTION:The speed change stages are divided into the low speed stage group and the high speed stage group, and the standard speed change stage is obtained from a speed change map consisting of the car speed - engine load, and if the standard speed change stage belongs in the low speed stage group, the standard speed change stage is set as the aimed speed change stage. Accordingly, the number of programs which are digested up to the determination of the speed change stages can be reduced exceedingly. When the speed change stage belongs to the high speed stage group, fuzzy estimation is carried out in consideration of other traveling condition (traveling parameters), and the optimum speed change stage is determined, and in this case, the aimed final speed change stage is selected from the high speed stage group. Accordingly, even if a fail is generated in a part of the sensor group, the down-shift to the low speed stage region is prevented.

Title: Amplification photoelectric transducer and its driving method
Inventor: ISOGAI TADAO
IPC: H01L31/10
Filed: 1993-12-01
Abstract: PURPOSE:To obtain large amplification by accumulating charge in a photoelectric conversion part, generating an impact ionization phenomenon through high- level or low-level voltage difference between a source and drain, accumulating the charge according to the respective levels, and providing a driving means to generate secondary charge based on the total quantity of charge as well. CONSTITUTION:A light is made incident into a photoelectric conversion part with a PN joint generated by a well 6 and an Si substrate 7 and the charge generated after converting the light photoelectrically is accumulated. Then a current passes between a source 1 and drain 5, and an impact ionization is generated by making the voltage difference large, and the generated charge is accumulated. Furthermore, a current passes between the source 1 and drain 5, and the voltage difference is made small so as to generate secondary charge based on the total quantity of charge that is generated through photoelectric conversion and impact ionization phenomenon. Thus S/N can be improved because no output amplifier is used for amplification.
