Title: Automatic agc control circuit in receiver
Inventor: ENDO HIROYUKI
IPC: H03G3/20
Filed: 1991-10-25
Abstract: PURPOSE:To prevent excess noise output by suppressing the gain increase of an automatic gain control circuit when a sudden decrease in a reception level is detected and releasing the gain suppression of the automatic gain control circuit when the reception level is restored. CONSTITUTION:When a transmission output from an opposite communication equipment is interrupted, the reception level of a reception signal is rapidly decreased. A detection means 22 detects a rapid change in the gradient of the reception level. A control means 23 suppresses the increase in the gain of an automatic gain control circuit 21 at a point of time of the detection of the rapid decrease to release the gain suppression by the control circuit 21 when the reception level is restored from the decreasing state. Furthermore, When fading takes place, the reception level of the reception signal is slowly decreased and the level again rises slowly attended with the release. In this case, the detection means 24 and the control means 25 implement the gain suppression and release of the control circuit similarly to above. Thus, it is prevented that noise is excessively amplified increasing too much noise power.

Title: Constant car speed holding device for motor bicycle
Inventor: KIKUTA JUNJI
IPC: B60W30/00
Filed: 1987-12-04
Abstract: PURPOSE:To make it possible to simplify wiring by arranging a release switch giving the order to release the constant speed car running control in the vicinity of a throttle grip as a switch actuating when the grip is rotated at a power not smaller than the specified level of power. CONSTITUTION:When a throttle grip 1 is rotated at a power not smaller than the specified level of power, the reaction is given to the grip 1 from a sliding member 18, and as a result the rotation position of the member 18 is held by a cable member 2. Therefore, the member 18 is made to slide along a slat face resisting to the energizing force of an energizing means after abutting. This sliding makes the member 18 push the button of a release switch 15 for making the switch 15 give a releasing order to a control circuit so that the control circuit releases the control of constant speed car running. Since the captioned device is, as mentioned above, constituted in such a way that when the grip 1 is rotated, the switch 15 for the control of constant speed car running is actuated, the switch 15 can be arranged in the vicinity of the grip 1, and the wires of the switch 15 can be bound together with the wires extended from the group of other switches in the neighborhood of the grip 1. This leads to the simplification of wiring, and as a result, wiring work is facilitated.

Title: Solid state laser system
Inventor: IMAI HIROFUMI
IPC: H01S3/06
Filed: 1992-10-21
Abstract: PURPOSE:To reduce the aberration of main laser beams even if radiant beam intensity distribution of exciting light source is provided with anisotropy by a method wherein the long axial direction of said anisotropy in the intensity distribution of exciting light is made coincide with the axial direction in the higher thermal conductivity of a solid state laser medium. CONSTITUTION:The intensity distribution status L of the exciting light beams excited by the radiant light beams from a semiconductor laser chip 1 is to be made elliptical. The long axial direction of the ellipsis coincides with the axial direction c in the higher thermal conductivity of Nd: YVO4 to be the anisotropical solid state laser medium. At this time, the long direction of the exciting light intensity distribution feeds Nd: YVO4 to be the solid state laser medium with more heat but due to the lower thermal conductivity in the a-axial direction of the Nd: YVO4 than the c-axial direction, the thermal conduction in the c-axial direction exceeds that in the a-axial direction resultantly enabling the circular temperature distribution status to be formed. Through these procedures, the thermally excited double refraction effect due to the anisotropy of the exciting light intesity distribution can be offset by the anisotropy of the solid state laser medium thereby enabling the high quality laser beams having reduced aberration to be emitted.
