Title: Idle rotation frequency control device
Inventor: OBA HIDEHIRO
IPC: F02D41/16
Filed: 1986-09-10
Abstract: PURPOSE:To prevent an engine stop, by setting a learnt value of a control valve opening to maintain the idle rotation frequency at a specific value when the learning condition is realized, and controlling the control valve opening responding to the actual control valve opening and the learnt value when the feedback condition is not realized. CONSTITUTION:On the way of a bypass route 25 arranged to deture a throttle valve 24, an idle control valve 26 is provided to control the idle rotation frequency by converting the flow section area. The valve 26 is controlled by a feedback control device A to maintain the idle rotation frequency at a specific value when the feedback condition is realized. Also a learning condition device B is provided to set a learnt value of the control valve opening necessary to maintain the idle rotation frequency at the specific value. When the feedback condition is not realized, the actual valve opening is maintained when it is larger than the learnt value, while the actual opening is controlled to make larger up to the learnt value when it is smaller than the learnt value, by a control valve opening device C.

Abstract: PURPOSE:To make it possible to perform highly accurate measurement without special calibration for a reference surface by providing a reflection-photoelectric-type optical fiber sensor and an air-micro-type displacement controlling mechanism, moving a measuring probe, and performing the measurement. CONSTITUTION:An edge 3 of a probe 2 of a reflection-photoelectric-type fiber sensor 1 is made to face a surface to be measured 4. Optical fibers and bundled and inserted into the probe 2. The reflected light is measured. The distance between the edge 3 and the surface to be measured 4 is kept constant all the time with an air micro-type displacement controlling mechanism. When the light is emitted from a light emitting element 10 through the base end of a light projecting fiber 5, the light is reflected from the surface to be measured 4. the reflected light reaches photodetectors 13 and 11 through light receiving optical fibers 6 and the light projecting fibers 5 which are divided in front and rear and right and left parts. The currents which are generated in response to the amounts of the received lights are converted into voltage signals in current/voltage converter circuits 14 and 12, respectively. The signals are inputted into reflectivity compensating circuits 15 in every direction. The signals are converted into the detected distance signal which does not depend on the reflectivity of the surface to be measured 4. As a result, the distance of the position which is slightly displaced in the directions of front and rear and right and left at the measuring positions of the surface to be measured is detected.

Title: Tape recorder
Inventor: TANAKA KIICHI
IPC: G11B15/02
Filed: 1986-09-10
Abstract: PURPOSE:To prevent the deformation of a roller and the magnetization of a head by permitting a voltage detection circuit to control an action. CONSTITUTION:When a switch 21 impresses a power source 25 to the voltage detection circuit 14, input/output terminals 22, 23 practically become the same potential. Then an electrolytic capacitor C1 in a power source circuit 13 is charged, and the collectors and emitters of switching transistors Trs Q1, Q2 are conducted, which leads an action circuit 12 to enter an action state. When a tape mechanism 11 is reproducing or recording, the voltage impressed to the circuit 14 becomes zero when the switch 21 is turned OFF. That means said voltage is below a reference one, therefore, the terminal 23 of the circuit 4 and the terminal 16 of the circuit 12 come to level '0' to start stop actions. The TrQ2 in the circuit 12 continues an ON action by the capacitor C1 for a while, and the TrQ1 continues an ON state as well. Both of them can be operated until a mechanism 11 is completely stopped by a mechanism action switching plunger 19. Therefore, the deformation of the pinch roller and the magnetization of the head can be prevented.

And, on the condition that displacement is constant and a hull first half part form is also constant, each parameter showing each hull form is systematically changed whereby calculation for each resistance value takes place, through which such a hull form as making viscous resistance in the hull as the total amount of each resistance value is found. According to this method, such an optimum hull form as making the hull resistance smaller is securable without performing any model tests which must be repeatedly performed over and over.

Title: Air fan
Inventor: UENISHI TOMOAKI
IPC: F24F7/007
Filed: 1989-08-17
Abstract: PURPOSE:To extend the operation time period of an air fan by a method wherein a signal is output when the illuminance exceeds a specified value, and a switching device provided is brought in action by the signal in order to supply electric energy generated by solar cells to the air fan. CONSTITUTION:Until CdS elements 7 receives the solar light and the illuminance by the solar light reaches 32,000 lux, the input voltage to the-input terminal of a comparator 9 is lower than a specified voltage to be input to said terminal, so that the output voltage of the comparator 9 remains at 'H' level, causing an output circuit 5 to remain open. Therefore, electric current does not flow through a fan motor M. When the illuminance increases and the CdS cell 7 detects the illuminance of 32,000 lux, the input voltage to-input terminal of the comparator 9 becomes higher than that to + terminal instantly, so that the output voltage of the comparator 9 becomes 'L' level, causing the output circuit to be closed. Consequently, the fan motor M is connected to solar cells 1, and electric current flows through the fan motor M. Thereby, the operation time period of an air fan 3 can be extended.

Filed: 1994-08-17
Abstract: PURPOSE: To transfer the motion of a cylinder to a ball valve actuator at an accurate speed without any loss even though a bent part exists between a cylinder and the circular track of the movable arm of a rotary valve, by continuously arranging a plurality of balls in a line between the end part of the cylinder and the movable arm of the valve. CONSTITUTION: A cyliner 10 is a driving source for opening/closing a valve, and consists of a plunger 12 to repeat its reciprocating motion and a stick-like body 40 connectively arranged to the tip of the plunger 12. If a cylinder wall is bent along the outer circumference of a rotary valve, a means to transfer the motion of the cylinder along a bent surface is required to be provided. The position of the cylinder 10 and the position of the movable arm 22 on the track of the rotary valve 20 are not rectilinearly positioned and the cylinder wall is connected to and bent along the circumference of the rotary valve 20, thus a plurality of spherical bodies (balls) 30 are arranged in a line between the cylinder 10 and the movable arm 22 of the rotary valve 20 as power transferring elements. Thus, the motion of the cylinder 10 can be transferred at an accurate speed without any loss.
