Title: Servo mechanism for magnetic recording and reproducing device
Inventor: KOBAYASHI JUN
IPC: G11B15/473
Filed: 1985-03-06
Abstract: PURPOSE:To obtain quickly stable reproduced pictures after a start mode by giving phase control to a reference signal generator with a head switching signal synchronized with a drum motor in terms of phase for a period during which the drum motor reaches its steady revolving speed by speed control. CONSTITUTION:The revolving speed of a drum motor 13 and then the phase of a trapezoidal wave signal 21 are changed before the motor 13 reaches its steady revolving speed. Then the phase of the reference signal RP is also changed. Thus the constant phase relation is kept between the signals RP and the trapezoidal wave signal LH. When the motor 13 reaches its steady revolving speed, a switch 19 is closed by the switch signal given from a speed control circuit 18. At the same time, a switch 25 is opend. Thus the signal RP is ketp at the phase set immediately before the switch 25 is opened. The phase control signal delivered from a sample holidng circuit 2 is fed back to the motor 13 via the switch 19, an addition amplifier 17 and a motor control circuit 16. Thus the motor 13 undergoes phase control.

Title: Fuel injector
Inventor: YAMADA KINSAKU
IPC: F02M69/00
Filed: 1985-03-06
Abstract: PURPOSE:To obtain the uniform fuel distribution performance all over the range of the throttle-valve opening-degree by forming the area of the intake passage partitioned by an injector into nonuniform and arranging a throttle valve so that the axis center is set parallel to the center line of the injector supporting part. CONSTITUTION:The area of the intake passage partitioned by an injector housing 2, injector pressing 3, and a body 1, namely the area of the opened port part 9 in correspondence with the underside of a throttle valve 4 is constituted smaller than the area of the opened port part 10 on the opposite side. Further, the axis center of a throttle valve shaft 5 is formed to be parallel to the direction of the axis center of an injector pressing 3. Therefore, the air stream does not concentrate towards the underside of the throttle valve 4, and the concentration of the fuel which flows in from an inlet 7 to the underside of the throttle valve 4 by the aid of air stream is prevented. Therefore, the nonuniformity of the fuel stream due to the throttle valve 4 in the range where the opening degree of the throttle valve 4 is large can be made uniform, and the fuel distribution to the engine can be made uniform.

Abstract: PURPOSE:To attain a security monitoring function with a low cost by providing a detection means to detect the variation in video signals obtained by a camera device, and making control of the shifting between an intermittent recording status and a normal recording status possible by using a detection signal generated by said detection means. CONSTITUTION:The image of an object passes through a focus lens 1 and enters an image pickup part 2, and from thus obtained video signal upsilon, a focus fitness decision circuit 3 detects the blurring of focus, a thus obtained output signal representing the amount of focus shifting is made a control signal (d) with which a motor driver 4 drives a motor 5 in order to move the focus lens 1 to sharpen the focus. In case of picking up the image of a still object, if the focus is once set, the control signal (d) which is the output of the circuit 3 does not vary. If a moving object appears and the focus come out of order, the control signal (d) varies, and a signal (u) representing this variation of control signal (d) is generated, which is made an alarm input to a VTR 6 to drive it into the alarm recording status. By holding the signal (u) for a determined period of time after the control signal (d) stops varying, the operation of the VTR 6 can be stabilized.

IPC: C09K17/00
Filed: 1989-02-27
Abstract: PURPOSE:To make it possible to obtain a grouting effect excellent in permeability and solidifying properties by preparing a grout which can absorb a prescribed amount of CO2 at a low pressure and has a long gelling time by supplying CO2 into a circulating aqueous water-glass solution. CONSTITUTION:Water-glass is supplied into a water-glass circulating system 1 from an aqueous water-glass solution supplying mechanism 2 via a line 5 and a valve 6. CO2 is supplied to an arbitrary part of the circulating system 1 from a CO2 supplying mechanism 3 via a line 7 and a valve 8. The CO2 is dissolved and absorbed into the circulating aqueous water-glass solution to give a grout. The resulting grout is sent to a grouting mechanism 11 via a valve 9 and a line 10, and is injected into ground. This process gives grout which has a precisely adjustified gelling time and especially has a long gelling time. Further, even if the pressure lowers in the ground, no vaporization of CO2 occurs, and sufficient solidifying time and solidifying function can be exhibited. Since no high-pressure tank is required, the apparatus is simplified, and can also be easily operated.

Abstract: PURPOSE:To decrease the burden of a person in charge of time measurement and to prevent an error in time measurement by sounding a means for sounding, such as a buzzer, a prescribed number of times when the count value of a 1st time measuring means attains a prescribed numerical value. CONSTITUTION:A register 2 is inputted with the time inputted by ten key switches 1. A subtractor 4 subtracts the time stored in a memory 3 from the set time and the result thereof is set in the 1st time measuring means 5. The output of a means 6 which delivers clock pulses is applied as the pulses of the second to the means 5. Since the means 5 is a subtraction type, the means makes subtraction operation by one second each every time the clock pulse is inputted thereto. A control means 8 generates alarms of a prescribed number of times when the content of the means 5 attains for example, 3 minutes and 0 minutes remaining time. The 2nd time measuring means 14 is an addition type and measures the question time. A coincidence circuit 15 applies a coincidence signal 16 to the means 14 and the means 8 when the contents of the means 14 and the memory 3 coincide. The means 8 sounds the sounding means 9 upon receipt of this signal 16.
