Title: Device for controlling continuously variable transmission
Inventor: HISAMURA HARUYOSHI
IPC: B60W10/10
Filed: 1986-02-18
Abstract: PURPOSE:To prevent a sudden engine brake action or the overrun of an engine by operating a feedback control using an integral value of deviation when a vehicle speed signal becomes zero. CONSTITUTION:The feed forward control position of a speed change actuator is determined based on both or either of a vehicle speed or an engine load by a feed forward control means. At the same time, the target value of the input speed of rotation or the change gear ratio of a continuously variable transmission is determined by a target determining means. Then, the deviation between this target value and an actual value is operated by a deviation operating means and, then, integrally processed by an integral means. And, by adding a feedback control quantity based on the deviation and the integral value to the feed forward control position, a speed change signal is outputted to the speed change actuator, from a first speed change commanding means when a signal which indicates a vehicle speed is not zero while the deviation is above a defined value, and, from a second speed change commanding means when a signal which indicates a vehicle speed is zero or when deviation is below the defined value.

Title: Quartz vibrator potassium biosensor
Inventor: GOTO MASAO
IPC: G01N5/02
Filed: 1991-01-31
Abstract: PURPOSE:To easily and inexpensively measure the amount of a potassium ion by forming a lipid film of valinomycin on the surface of a quartz vibrator to measure a frequency change. CONSTITUTION:A quartz vibrator potassium biosensor 25 using a quartz vibrator 24 having a valinomycin lipid film formed on the surface thereof is immersed in an aqueous potassium solution and frequency is measured by a frequency counter 26. In this case, since said frequency changes corresponding to the wt. change of the substance bonded to the surface of the vibrator as shown by formula  F=KX m (F: frequency change quantity, K: constant,  m: adhesion wt. change), the amount of potassium can be measured by calculating the change of frequency. Since the quartz vibrator potassium biosensor 25 is constituted by forming only the valinomycin lipid film on the surface of the quartz vibrator 24, this biosensor is inexpensive and the measuring operation thereof is also simple.

Title: Manufacture of rare earth-iron permanent magnet
Inventor: HAYASHI NOBUO
IPC: C22C38/02
Filed: 1988-02-15
Abstract: PURPOSE:To stably obtain a permanent magnet having a fixed coercive force by a method wherein, after a magnet alloy has been sintered and age-treated, a cooling treatment is conducted in a specific temperature range at the cooling speed of 10 deg.C/min. or above. CONSTITUTION:An aging treatment is conducted on the sintered alloy consisting of the rare earth element-iron-boron alloy which is used on a rare-earth magnet, and ordinarily the temperature range of 600-700 deg.C is considered desirable as the aging treatment temperature. After the aging treatment has been finished, the sintered alloy is cooled down from the temperature of 570 deg.C or above to at least 470 deg.C or below at the cooling speed of at least 10 deg.C/min. or above. It is necessary that the cooling treatment at the above-mentioned speed is started at least at the aging treatment temperature of 570 deg.C. At this point, if the!starting temperature of said cooling treatment is lower than 570 deg.C, sufficient coercive force is not acquired, and also sufficiently excellent coercive force is not obtained when said cooling speed is not maintained at the temperature lower than 470 deg.C. As a result, the permanent magnet having high coercive force and fixed magnetic characteristics can be obtained in a stable manner.

Abstract: PURPOSE:To ensure satisfactory production stability and high sensitivity and to maintain superior mechanical strength and electrophotographic characteristics over a long time by using plural kinds of polycarbonate resins each having a specified mol.wt. as the bonding resin of a photosensitive layer. CONSTITUTION:A photosensitive layer contg. an electric charge generating material 2 and an electric charge transferring material 3 is disposed on an electric conductive substrate 1. The thickness of the photosensitive layer is >=27mum and polycarbonate resin (low mol.wt. component) having 10,000 to <22,000 number average mol.wt. (Mn) and polycarbonate resin (high mol.wt. component) having 22,000 to <38,000 Mn are contained as the bonding resin of the photosensitive layer.

Title: Controller for electromagnetic powder type clutch of vehicle
Inventor: TAKANO TOSHIO
IPC: B60W10/18
Filed: 1980-03-15
Abstract: PURPOSE:To effectively and safely transmit the motive power of an engine to wheels, by detecting the working conditions of the engine in terms of signals from various switches and controlling an electromagnetic powder type clutch depending on the working conditions. CONSTITUTION:When the speed of a vehicle has exceeded a set level, a signal is supplied from a vehicle speed sensor 42 to a judgment circuit 72 to shift the output of the circuit 72 toward a clutch hold switch 70. For that reason, when an engine is accelerated by depressing an accelerator pedal over one fourth of its travel, the clutch hold switch 70 is turned off to disconnect the judgement circuit 72 from a current control circuit 73. Consequently, a change lever switch 39 is turned on so that no speed-changing operation signal is applied to the control circuit 73 even if speed- changing operation is detected and that a current flows through a coil 7 and a clutch is not disengaged. As a result, to shift gears under high-speed running, the accelerator pedal needs to be returned to close the switch 70 and perform speed-changing operation under no high-speed revolution.
