Title: Controller for speed of direct current motor
Inventor: HIZAWA MAMORU
IPC: H02P7/293
Filed: 1980-04-09
Abstract: PURPOSE:To obtain a speed controller which can acquire more stable revolution ranging over a high-speed region from a low-speed region by a method wherein a gradient of saw tooth wave signals compared with speed feedback signals is made constant, and the offset value is changed in response to speed set value. CONSTITUTION:A transistor Q2 is under an OFF condition just before an end point from a starting point of each half-wave period of AC line voltage, and a capacitor C2 is charged through a resistor R12. The transistor Q2 is under an ON condition during the time up to the end point from just before the end point of the half-wave period, and the capacitor C2 is discharged through resistors R12, VR and R13. The offset value VE of saw tooth wave signals VC obtained at both ends of the capacitor C2 changes in response to the value of the resistor VR for adjusting speed. An angle of conduction of a controllable semiconductor element is decided according to a point of time when the saw tooth wave signals VC and speed feedback signals VN agree.

Title: Production of magnetic recording medium
Inventor: FURUSAWA KENJI
IPC: C23C14/36
Filed: 1985-03-11
Abstract: PURPOSE:To obtain a vertical magnetic anisotropic film for rigid magnetic disc superior in orientation property and magnetic characteristic by narrowing the incidence angle of vapor-deposited particles to a substrate in an initial stage of vapor-deposited film formation. CONSTITUTION:In consideration of the fact that the C-axis orientation property of the whole of the film is determined by that in the initial stage of film formation, the incidence angle of sputter evaporated particles of magnetic materials to the surface of the substrate is set to an angle approximating 90 deg. to the surface of the substrate in the initial stage of thin film formation when magnetic materials are sputtered to form a thin layer of a magnetic recording medium on the surface of the substrate. The orientation property and the magnetic characteristic are improved in this manner and vapor-deposition purposing to make the film thickness distribution and the characteristic distribution uniform is performed thereafter to form the vertical magnetic anisotropic film. The continuous execution of these two processings in the same device is desirable with respect to the workability, pollution of the film, etc. The planar magnetron sputtering method where the plasma diameter can be varied by a double magnetic pole structure yields to this request.

Title: Pointing device
Inventor: KURASHIMA SHIGEMI
IPC: G06F3/0338
Filed: 1991-03-12
Abstract: PURPOSE:To form a comparatively compact pointing device with a simple structure by fixing either one of a magnet and a magnetic resistance element to an operation part and fixing the other to a supporting means. CONSTITUTION:The magnetic resistance element 32 and the magnet 30 can be relatively moved, and when the element 32 detects magnetic force generated from the magnet 30, relative positional relation between the element 32 and the magnet 30 can be detected. Since either one of the element 32 and the magnet 30 is fixed to the operation part and the other is fixed to the supporting means, the position of the operation part against the supporting means can be detected. Since a mechanical coupling means is not arranged between the element 32 and the magnet 30 and the element 32 does not require a wide position, the structure can be simplified as a whole and the device can be comparatively compactly formed.

Title: Paper feeding device of image forming device
Inventor: ICHIHASHI MIKIO
IPC: G03G15/00
Filed: 1995-03-07
Abstract: PURPOSE: To prevent breakdown of the device due to erroneous handling of an operator by providing a guide guiding a lock member so as to be locked, when a paper feed cassette under the condition in which the lock member is not locked is inserted into the opening on the device main body side or drawn out from the opening. CONSTITUTION: When an operator forgets to lock a cassette cover 40 and intends to insert a paper feed cassette 30 into a paper feed device 2, the second contact part 45 of the cassette cover 40 is brought in contact with a third guide 27. Hereby, the cassette cover 40 is energized while setting a cassette cover supporting shaft 41 as a fulcrum. By the hook 42 of the cassette cover 40, the cassette cover 40 is locked with the paper feed device 2. Consequently, the paper feed cassette 30 can be smoothly inserted up to the depth. When the paper feed cassette 30 is inserted, the third guide 27 locks the cassette cover 40 in the anticlockwise direction, and hence a segment roller 23 is not contacted with the cassette cover 40, and there is no possibility to break down the segment roller 23 or the cassette cover 40.

Title: Production of carbon material for sliding current collection
Inventor: FUJIMOTO KENICHIRO
IPC: B60L5/04
Filed: 1990-02-28
Abstract: PURPOSE:To obtain a high-strength carbonaceous material for sliding current collection having a low electrical resistance and resistance to brittle fracture by mixing raw coke with a specific amount of metal fiber, then forming the resultant mixture and burning the formed compact. CONSTITUTION:With raw coke, is added and mixed 25-60vol.% metal fiber. The resultant mixture is then formed and burned to provide the objective carbon material. Pulverized raw coke itself containing a binder component is suitable as a carbonaceous raw material to be used. A large amount of the metal fiber can be added only by using the aforementioned raw material. For example, methods for heating pitch such as petroleum-based or coal-based pitch in an inert gas stream under ordinary pressure and regulating volatile contents or regulating the volatile contents according to vacuum distillation are cited as a method for producing the above-mentioned raw coke. If it is desired to further improve sliding characteristics, a carbonaceous raw material containing graphite powder dispersed in a carbonaceous matrix composed of the raw coke is effectively used.
