Title: Magnetic recording medium
Inventor: OGAWA HIROSHI
IPC: C09D5/23
Filed: 1985-05-16
Abstract: PURPOSE:To form a double-layered magnetic recording medium having an excellent electromagnetic conversion characteristic by incorporating polycarbonate polyurethane therein as a binder. CONSTITUTION:The binder for the upper layer and/or the binder for the lower layer contains the polycarbonate polyurethane. The thickness of the magnetic layer is particularly preferably 0.5-2mu for the upper layer and particularly preferably 2.0-4.0mu for the lower layer. The polycarbonate polyurethane used is obtd. by condensing polyol, polyisocyanate and if necessary a chain extender. The polyurethane having 10,000-120,000 average mol.wt. can be utilized. The durability of a tape is deteriorated if the mol.wt. is smaller than said range and the solubility of the resin is deteriorated and such deterioration is undesirable from an industrial view point if the mol.wt. exceeds said range.

Title: Semiconductor porcelain with positive temperature coefficient of resistance
Inventor: NIIMI HIDEAKI
IPC: H01C7/02
Filed: 1991-04-09
Abstract: PURPOSE:To obtain a positive resistance temperature coefficient having the low specific resistance at room temperature by bringing the content of chlorine of a barium titanate semiconductor porcelain, which has a positive temperature coefficient of resistance, to 0.01 atomic % or lower. CONSTITUTION:Powder is formed by compounding BaCO3, BaCl2, TiO2, SrCO3, La2O3 and MnO2. The compounded powder is pulverized, mixed, dried up by evaporation and baked. After 5wt.% polyvinyl acetate binder has been added and mixed to the baked powder, they are dried up and formed into a circular molded body by a press molding machine. This molded body is baked in the atmospheric air, and a calcined body is formed. An electrode is formed on both main surfaces of the baked body by applying an In-Ga alloy. As a result, the specific resistance at room temperature can be reduced sharply without deterioration of the temperature coefficient of resistance, and the adaptability for a small-sized large-current element can be accomlished.

Title: Three-dimensional image input device
Inventor: AOKI HARUMI
IPC: G01S17/10
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To obtain the three-dimensional image input device that is made small in size at a low cost without the need for provision of an optical shutter and provides a sufficiently high output. SOLUTION: A charge sweep-out signal S2 is outputted synchronously with an output of a vertical synchronizing signal S1. Thus, unwanted charges having been stored in a photo diode are swept out in a direction of a substrate. As soon as outputting of the charge sweep-out signal S2 is finished, a range finding optical pulse S3 with a prescribed pulse width is outputted. A CCD detects a reflected light S4 in a measured object receiving the range finding optical pulse S3. After the lapse of a prescribed time from outputting of the range finding optical pulse S3, a charge transfer signal S5 is outputted and the charges stored in the photo diode are transferred to a vertical transfer section. The vertical transfer section integrates signal charges S6 by repetitively outputting the range finding optical pulse S3 and the charge transfer signal S5.  This signal charge S6 corresponds to distance information up to the measured object.

Title: Motor-driven type power steering
Inventor: MORISHITA MITSUHARU
IPC: B62D5/04
Filed: 1990-04-19
Abstract: PURPOSE:To improve the safety by providing a motor for energizing steering torque according to the largeness and direction of steering torque, a judging circuit for judging the high and low to the specific speed or engine speed, a resistance series-connected to the motor, and a switching element between both ends of this resistance. CONSTITUTION:A vehicle speed judging circuit for judging the high and low to the vehicle speed (20-50Km/h) is formed of a vehicle speed sensor 12, an F/V conversion circuit 950, resistances 951, 952 and a fifth comparator 953. When this judging circuit judges the vehicle speed is low, a relay 961 (switching element) short-circuits a resistance 960, so that a large current flows to a motor M7 to energize steering in the specified largeness and direction. When the judg ing circuit judges the speed is high, the relay 961 is opened, and the resistance 960 is series-inserted into the motor M7 so as to suppress the current of the motor M7 and thereby suppress the energizing action of steering. Excess current does not therefore flow in the same direction even if abnormality is generated for some reason during high speed running.
