Title: Optical information recording and reproducing device
Inventor: HOSOYA HIDEKI
IPC: G11B7/085
Filed: 1986-12-16
Abstract: PURPOSE:To obtain a proper response speed at the time of leading-in a servo and at the time of detecting out of servo by switching the frequency characteristic of a signal inputted in a comparator which detects whether or not projecting light is near a focus by means of the alteration of the quantity of light incident on a photodetector. CONSTITUTION:When an objective lens comes close to a medium, a difference signal and a sum signal alter. And when an output from a control logic 111 becomes 'H', both inputs of a NAND Gate 112 become 'H', so that an analog switch 104 is switched to an (a) contact side and a servo loop is formed. At the same time a lens driving circuit 106 stops outputting a sine wave or a saw tooth wave. And also the analog switch 107 is switched to the (a) contact side and a low pass filter 108 is inserted between an adder 102 and an optical comparator 109. When the servo comes nearly off, the output from the control logic 111 becomes 'L' and the analog switch 104 is switched to a (b) contact because the output from the light quantity comparator 109 becomes 'L'. At the same time, the lens driving circuit 106 generates a leading-in wave and releading-in of a focus servo is executed.

Abstract: PROBLEM TO BE SOLVED: To miniaturize the whole joint through axially short-sized structure by providing a base part movably at an opening end part of a joint body through a support member protrusively provided with a cylindrical insert, and pressing a claw wall part inward by contact engagement with an inclined face of the joint body. SOLUTION: In association with the simultaneous follow-up movement of a collet member 4 caused by slight retreat of a resin tube P after being fitted into an insert 3' part and insert-fitted into a space part, a claw wall part is pressed inward to bite into the peripheral surface of the resin tube P by contact engagement with an inclined face 2' on the joint body 1 side at an outer part of a claw wall 4'. In case of releasing the resin tube P, thread-fastening to an opposed member through thread parts 1''' of the joint body 1 is unfastened, and then the resin tube P is released immediately from a flareless state at a claw wall 4' part by slight forward pressing movement of the tube. Miniaturization can be attained through the axially short-sized structure of the joint body.

Title: Driving force control device for vehicle
Inventor: IWATA TORU
IPC: F02D43/00
Filed: 1994-12-01
Abstract: PURPOSE: To control an opening satisfactorily and meet the requirements for reduction of driving force by using a simple device which drives the opening to a stall preventing opening even if it is a small opening required for suppression of slippage. CONSTITUTION: A negative pressure diaphragm device 15 and a three-way solenoid valve 21 are provided in the intake path of an engine as a second throttle valve 4 driving actuator provided in series with the throttle valve. When slip occurs, the three-way solenoid valve 21 is turned on to lead a negative pressure to a negative pressure diaphragm device 15 so as to drive it the full close position of approx. 1/8 opening. Also, after the slip has been reduced, the three-way solenoid valve 21 is turned off to lead atmospheric pressure to the negative pressure diaphragm device 15 so as to hold it to the full open position. However, when it is returned from the full close position to the full open position, it is driven by ON-OFF repeated signals of a duty ratio determined according to the coefficient of friction (μ) on vehicle traveling road surfaces. Then, as the (μ) on the road surfaces is lower, the opening operation speed is reduced so as to prevent slipping at re-acceleration.

Abstract: PURPOSE:To stabilize multi-layer welding by operating a bead width in a prescribed layer from welding particulars, also deriving a weaving width and/or the number of passes in the next layer, based on said bead width, and executing the welding, based on them. CONSTITUTION:In order to operate an optimum build-up condition, three kinds of data of a size of a welded joint part, welding particulars, and a welding current are inputted. In case of executing one layer one pass welding, a bead thickness DELTAT1 at the time of one layer welding is stored, therefore, a bead width W1 after one layer has been ended is calculated, based on the data. The second layer is welded by executing the weaving of a narrower width than the bead width W1. Also, a bead width W2 after the second layer has been welded is obtained from a bead thickness of the first layer and the second layer DELTAT1+DELTAT2, and a joint dimensional data. The same procedure is repeated until a prescribed plate thickness and a prescribed height of a reinforcement of weld are obtained. According to this method, an optimum welding condition can be set, the work is simplified and the welding quality can be stabilized.
