Title: Radio image transmitting equipment
Inventor: SAKAI TAKEOKI
IPC: H04N5/00
Filed: 1984-11-21
Abstract: PURPOSE:To improve the operationality and the movement of a TV camera when used by sending carrier constantly and video signals and audio signals intermittently, and causing a receiving side to generate control signals for start/ stop of the VTR in addition to the video signals and audio signals. CONSTITUTION:Since a transmitting circuit continues to transmit signals as long as contacts of switches SW1 and SW2 are turned on, start/stop signals at VTR side keeps start state. When the contacts of the switches SW1 and SW2 are turned off, the video signals and audio signals do not input in a RF modulation circuit 3. Then, carrier alone are output from the RF modulation circuit 3 and are transmitted from an antenna 5. The VTR receives this carrier, but can't drive a VTR starting relay because the video signals and audio signals are not included. As a result, a relay contact is turned off, the tape running of the VTR is stopped.

Title: Printed-wiring board
Inventor: NAKATANI NAOTO
IPC: H05K1/18
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent the formation of a bridge, which consists of conductive bonding agents, between pads or between the pads and other circuit pattern by a method wherein a recessed part is formed between the pads and the other circuit pattern approaching these pads and excessive conductive bonding agents, which are associated with a mounting of a surface mounting component, are introduced in the recessed part. SOLUTION: Conductive bonding agents 222 are respectively fed to pads 214 and 214 by a printing method and thereafter, if a chip component 232 is placed on the agents 222 and is pressed with a prescribed pressure, one part of each bonding agent 222 flows out from each pad 214 or 214 and flows in a groove 230. The capacity of this groove 230 is set fully large compared with the amount of flowout of the agents 222 from the pads 214. Owing to this, there is no possibility that the agents 222 and 222 flowed in this groove 230 from the two pads 214 and 214 come into contact with each other. As a result, the reliability of a wiring board 210 mounted with the component is increased. Moreover, as the intervals between the pads 214 and a circuit pattern, which is located near the pads 214, can be made narrow, the wiring board 210 is suitable to an increase in a high-density mounting.

Title: Stop controller of motor
Inventor: OBA YASUMASA
IPC: H02P3/10
Filed: 1984-11-27
Abstract: PURPOSE:To accurately control the stopping position of a motor without an overbraking state by abruptly decelerating the motor until the motor is decelerated to the speed immediately before stopping and then relatively slowly decelerating it. CONSTITUTION:When a stop command is given, brake command generating means 1 generates a brake command signal, and a motor energizing circuit is controlled to supply the first brake current to the motor by brake current supplying means 6 at this time. The rotating speed of the motor is abruptly decelerated by the first blanking mode. When the speed of the motor is reduced to the first set speed, braking current switching command generating means 2 produces a braking current switching command output. The ratio of decelerating the speed is smoothed by the second blanking mode. Then, stop command generating means 5 generates a control current supply stop signal after a suitable delaying time is elapsed. Control means 6 stops supplying the braking current by the signal. At this time the motor is not reversely rotated.
