Title: Semiconductor storage device
Inventor: SUMI SHINJI
IPC: G11C11/419
Filed: 1985-09-11
Abstract: PURPOSE:To attain a high-speed operation of a semiconductor storage device by providing a PMOSFET which keeps an equal potential for the output level of a differential amplifier for data given from a data line and a NMOSFET to which the signal complementary to the PMOSFET is applied. CONSTITUTION:A pair of complementary data signals phi0 and phi1 are turned into the input signals of a differential amplifier after the data held in a memory cell are delivered. While the differential amplifier delivers the complementary output signals Va and Vb. The signal phiP of a low level is produced with changes of the address signal and then set at a high level after a fixed period of time. A PMOSFET Q6 and an NMOSFET Q7 are turned on while the signal phiP and the inverse of phiP are kept at low and high levels respectively. Then a short circuit is produced between a pair of output terminals of the differential amplifier and the same potential is secured between both signals Va and Vb. Thus an equal potential is secured stably for the output of the differential amplifier. Then data are delivered satisfactorily to accelerate the access time.

Abstract: PURPOSE:To surely prevent falling off or shifting by inserting the projecting portions of a thrust washer into the through holes of a rotary member and engaging the thrust washer by the rising faces of claws which are projected out on the opposite face of the rotary member. CONSTITUTION:A thrust washer 3 is installed on a rotary member (hub for second brake B2) 1 with the projecting portions 3a thereof being fitted to the through holes 1a of the rotary member 1 and pressed in. At this time, the claws 3b of the thrust washer 3 are deflected with the taper faces (a) thereof being brought into contact with the outer peripheral faces of the through holes 1a, while this deflection is released as the claws 3b are projected out to the opposite face through the through holes 1a. A rising faces (b) are engaged with the opposite side face of the rotary member 1 being surely stopped from falling off. In this condition, in whatever posture the rotary member 1 may be assembled at the time of assembling an automatic transmission, no falling off nor shifting can take place.

Title: Cylindrical base body for electrophotographic sensitive body and its production
Inventor: YAMAGUCHI KEITARO
IPC: G03G5/10
Filed: 1992-07-29
Abstract: PURPOSE:To prevent the generation of longitudinal striae patterns on a print by removing the surface layer of a pipe of a prescribed length obtd. by extrusion processing of a mandrel and subjecting this mandrel to drawing. CONSTITUTION:The mandrel pipe obtd. by hot extrusion processing is previously cut to the required length. The extrusion processed and cut pipe is elongated in length about 3 times by the drawing. Then, the treatment area is decreased to about 1/3 as compared with the treatment to be executed after the drawing if the outside surface cutting is executed before the above-mentioned drawing. The treatment is thus executed at a low cost. The cutting of the outside surface of the mandrel pipe is then executed. The cutting depth is adjusted according to an unequal thickness quantity. The cylindrical base body is obtd. by the drawing after the mandrel pipe is adjusted in the unequal thickness and after the surface defects on the outside surface are removed. The generation of the longitudinal striae patterns on the print does not arise even with the cylindrical base body which is merely provided with the photosensitive layer without providing the surface thereof with an under coating layer.

Abstract: PURPOSE:To enable a magnetic flux generated by a bias magnet to concentrate on a light beam irradiating position and to attain the manufacturing of a small- scale optical system driving device by forming the protecting outer frame of a lens body with a ferromagnetic body. CONSTITUTION:A photoelectro-magnetic information device 6 is a device that drives an objective lens 5 magnetically, and is contained in a protecting outer frame part 8, at the bottom of which a hole 7 for light transmission is provided. The protecting outer frame 8 is a frame made of the ferromagnetic body, protecting the surface of the lens from the attachment of dust, etc. With energizing a coil 10, since the magnetic flux in a yoke passes through the protecting outer frame 8 provided on an optical disc 1 from a projecting center part 9a in a yoke 9 and flows on the outer peripheral part 9b of the yoke 9, a leakage magnetic flux can be reduced. Thereby, it is possible to concentrate the magnetic flux at a recording area (recording bit) on the disc 1. And it is no need to prepare a large electromagnet or to increase the winding number of a coil or to give an excess for the procurement of the magnetic flux having a required intensity.

Title: Preparation of silicon nitride
Inventor: YOSHIZUMI MOTOHIKO
IPC: C01B21/068
Filed: 1982-11-19
Abstract: PURPOSE:To lower the temperature for the formation of silicon nitride, to shorten the reaction time, and to increase the content of alpha-type silicon nitride, by adding metallic copper or a copper compound to powdery metallic silicon, and carrying out the nitriding reaction. CONSTITUTION:Metallic silicon powder is added with one or more compounds selected from metallic copper, copper fluoride, copper chloride and copper oxide, and nitrided. The amount of the copper (compound) is 0.5-10% (in terms of metallic copper) based on silicon. The nitriding reaction proceeds only 2-3% even at 1,300 deg.C in the absence of metallic copper and copper compound; however, the addition of the substance enables the nitriding degree of 100% by the reaction at 1,300 deg.C for 2hr or >=90% by the reaction at 1,250 deg.C. Furthermore, the content of alpha-crystal in the product reaches >=95%. Since the reaction temperature can be lowered and the reaction time can be shortened, the sintering of particles is prevented and fine powder is obtained.

Abstract: PURPOSE:To measure a grain size distribution continuously by forming a Fraunhofer diffraction image of particles, detecting the diffraction image intensity I(omega) at a point which is distance omega away radially from the center of the diffraction grating, and obtaining a function in which specific numerical conversion of the intensity is performed. CONSTITUTION:Coherent light 2 emitted by a light source 1 is collimated by optical systems 3 and 3' into parallel light, which is projected on a particle group 4, and transmitted light 2 is passed through a Fourier transform lens 5 to form a Fraunhofer diffraction image on a surface 6. Light intensity I(omega) at each radial position in the diffraction image is converted by a photoelectric converting device 7 into an electric signal, which is inputted to a signal processor 8; the processor 8 imposes linear Hankel transform on the function in which the distance omega is multiplied by the intensity I(omega) radially from the center of the diffraction image to obtain a function H(x) containing (x) as a variable. Then, this is Fourier-transformed to obtain a function including xsi as a variable, and linear Hankel transform is imposed on a function obtained by multiplying the function F by xsi, thereby calculating the grain size distribution.
