Title: Digital control device for dc motor
Inventor: NOJIRI YUKO
IPC: H02P7/06
Filed: 1986-04-14
Abstract: PURPOSE:To enable soft start-stop, by a method wherein energizing duty to a DC motor is increased or decreased by a definite value for a definite time. CONSTITUTION:A control means 3 dirscriminates acceleration or deceleration based on speed command 4. If acceleration is discriminated, present energizing duty is increased by definite value, and after a lapse of definite time it is discriminated whether speed of a motor 1 from an encoder 2 becomes the command speed or not. If not, after a lapsed of definite time, the process is returned to increase of energizing duty. If deceleration is discriminated, the energizing duty is decreased by each definite time. In this constitution, even if the speed command value does not vary linearly with respect to the rotational speed, the soft start-stop can be performed.

Title: Pressure sensor device
Inventor: NAKAMURA MASAKI
IPC: G01L9/12
Filed: 1982-05-18
Abstract: PURPOSE:To obtain a pressure sensor device whose temperature fluctuation is small, by combining a series circuit of first and second capacitors whose electrostatic capacities are changed in correspondence with the change of pressure, a voltage generating circuit, and a comparator amplifier circuit which compares a voltage across the capacitor and a reference voltage. CONSTITUTION:A voltage generating circuit 1 is constituted by a transistor (TR) 7 which is switched by the output of an oscillator 6 and resistors. A series circuit 2 is constituted by a first capacitor 10 and a second capacitor 11 whose electrostatic capacities are changed in correspondence with the change of pressure. When the input voltage is applied to the siries circuit 2 and the TR 7 is OFF, an output voltage is Vout. When the TR 7 is ON, the output voltage is 0V. At this time, the amplitude of the voltage at a connecting point is Cp/Cr+CP.Vout, where Cp and Cr are the capacities of the first and second capacitors, respectively. Negative feedback is applied by an operation amplifier 21 so that the output voltage of an amplitude detecting circuit 3 becomes a reference voltage which is obtained by a reference voltage generating circuit 4. When Vout changes by the change of the Cp, the relationship Vout =(1+Cr/ Cp)Vref is established, and the change in electrostatic capacity can be efficiently taken out as the change in voltage.

Title: Ball type universal joint and its manufacture
Inventor: FURANKU ARUBAATO JIYUNIA
IPC: F16D3/221
Filed: 1982-05-21
Abstract: A ball type universal joint construction where a ball member is rotatably received in a housing and a bearing structure interposed therebetween in a manner which limits the relative rotational degrees of freedom. The ball member has a spherical surface portion which includes axially extending bearing receiving slots and the housing has a cavity spherical surface portion which includes bearing receiving recesses in registry with the receiving slots. Ball type bearings disposed partially within the recesses and partially within the slots limit movement between the ball member and housing to articulated movement relative to each other. The housing also includes an access opening at one end face having an enlargement through which the ball member can be passed when rotated 90 degrees to its nominal, functioning position. This allows the ball member to be inserted into the housing through the enlargement while at the same time accommodating passage of the bearings into the housing recesses. Thereafter, the ball member is further rotated such that the receiving slots also partially receive the bearings and thus capture the ball member in an articulating, non-rotatable relationship in the housing.

Title: Boost pressure controlling device for supercharger
Inventor: MORITA YOSHIROU
IPC: F02B37/18
Filed: 1984-04-28
Abstract: PURPOSE:To control a supercharger in two stages to improve output while reduce the rate of fuel consumption by providing a closing valve in a bypass which bypasses a supercharging turbine and is connected to an exhaust passage, and operating said closing valve with two kinds of high and low boost pressure. CONSTITUTION:When a compressor 8 in a turbocharger type supercharger 2 rotates and the boost pressure reaches the maximum pressure, a relief valve 36 provided in a pressure introducing passage 32 is opened allowing the maximum boost pressure to flow to an actuator 20 side. Thereupon, a diaphragm 22 is displaced in the expanding direction of the pressure chamber 24 and opens a waist gate valve 18, to open a bypass 12. Therefore, exhaust pressure escapes to an exhaust passage 6 on the lower course side of a turbine 10, restraining the rotation of the compressor 8 by means of the turbine 10. In this case, if an exhaust temp. sensor 60 detects a temp. above a certain degree, a control part 58 opens a solenoid valve 38. Thereby, the boost pressure flows to the actuator 20 side, opening the bypass 12, and the boost pressure is lowered to the defined pressure.
