Patent JP-H03274984-A (JP)
Title: Optical transmitter
Inventor: KARISE SHIGERU
IPC: H04B10/00
Filed: 1990-03-26
Abstract: PURPOSE:To allow a receiver side to discriminate a voice signal automatically and to avoid difficulty of hearing by detecting it that a separated FM audio signal is changing in response to the output of a pulse signal. CONSTITUTION:A pulse signal generated from a transmitter side 3 is separated by a receiver 100 side and the pulse signal is synchronized with a field frequency of a video signal (a). Moreover, a level Co (c) of a subchannel audio signal is changed synchronously with the pulse signal at the transmitter 3 side and the change is detected by the receiver 100 synchronously with the pulse signal. Since the audio output is controlled automatically based on the detection signal, a disadvantage of difficulty of hearing or the like is avoided.

Title: Manufacture of eaves-gutter joint
Inventor: YAMAMOTO MASAHARU
IPC: B29C53/00
Filed: 1979-06-15
Abstract: PURPOSE:To set a water seal pushing sheet to a joint body with simple operation by a method wherein in manufacture of a synthetic resin eaves-gutter joint, elastic deformation is given to the joint body, a water seal pushing sheet is made to run along the inner circumference of the joint body and is fused with the joint body at both its side ends. CONSTITUTION:A joint body 1 is formed from hard synthetic resin in the form of a nearly semicircular section and fitting lugs 3 are set near the upper ends of both its side. A pushing sheet 2 is made from soft synthetic resin. In the manufacture, the joint body 1 is set in a form 4 giving bending deformation to the joint body 1 in order to reduce its inner diameter and the pushing sheet 2 is placed so that it can stick to the inner circumference of the joint body 1. Then, the joint body 1 is fused with the pushing sheet 2 at the arrow portions by means of high frequency fusion or ultrasonic fusion. Finally, the joint body 1 is taken out of the form 4 and is restored elastically to the original form. At this time, a gap 5 appears between the pushing sheet 2 and the joint body 1. Since the eaves-gutter joint manufactured in this way sticks to the pushing sheet 2, water is prevented from leakage.

IPC: G11B21/08
Filed: 1990-03-28
Abstract: PURPOSE:To shorten travel time by providing a device which generates acceleration for the driving of an optical head corresponding to the residual distance of the optical head. CONSTITUTION:An acceleration generator 13 that is an open loop control system is attached in addition to the velocity control system of a closed loop. The acceleration generator 13 adds constant acceleration for acceleration/deceleration on a course actuator 9 while a velocity command value to perform the acceleration/deceleration at constant speed is generated. The travel of the device with high accuracy is not expected only by open loop control by disturbance acceleration based on the inclination or friction, etc., of the device. Therefore, a part not controlled only by the open loop control system is corrected with a closed loop system. Thereby, velocity follow-up characteristic can be improved, which shortens seek time.

Title: Magnetic recorder/reproducer
Inventor: ISHIDA SUMI
IPC: G11B27/17
Filed: 1979-06-18
Abstract: PURPOSE: To avoid the variation of the counter display when the tape ends, by counting the detection pulses only in the tape detection mode.  
     CONSTITUTION: When disk 9 is turned with running of tape 3, photodetector 11 is turned on only at the moment when slit 8 is positioned between light emitting element 10 and detector 11. Thus detector 11 is turned on and off with the frequency proportional to the rotational speed of rotor 4, i.e., the running speed of tape 3. Then tape 3 is rewound and thus counter circuit 16 carries out the subtraction. Under these conditions, tape 3 is all taken up to the side of supply reel stage 1, and then tension arm 5 is displaced to position (b). Thus switch 6 is closed, and input (b) and AND gate 14 features the L level. Accordingly, rotor 4 is turned by the inertia although tape 3 ends. And no pulse emerges at output (c) although the pulse is applied to input (a) of gate 14 from detector 11. As a result, circuit 16 never causes the count variation.
