Title: Operating machine such as motor chain saw
Inventor: GIYUNTAA BUORUFU
IPC: F02B63/02
Filed: 1990-10-22
Abstract: PURPOSE: To enable a chain saw to be surely supported by an operator in an optionally working state without much power consumption by designing the chain saw in such a manner that the rear end of a grip part is widened transversely at the longitudinal axial line of the chain saw to a receiving chamber and a wall part facing the grip part of the receiving chamber is used as a base for supporting the back of one hand of the operator. CONSTITUTION: The motor-driven chain saw has a hand grip which is suitable for supporting and operating a working device by one hand and is equipped with a grip 5a which is arranged on the upper face of a case 2 and extends in the longitudinal axial line 8 of the motor-driven chain saw. The grip 5a of the hand grip is located almost in the longitudinal axial line direction of the working device, and in this case, a throttle 11 arranged on the hand grip 5a is positioned almost above a center of gravity S to be given in such a state that the throttle 11 is connected to a working part. The other wall facing the grip part is formed as a base for the back of one hand of the operator, on especially both sides of the grip 5a. The operator surely supports the working device as described and the operator can compensate for a tilting motion around the longitudinal axial line 8 surely and with the use of a small force like a tilting motion in the back/forth direction around the center of gravity S.

Title: Voice band compressor
Inventor: NAKANISHI TADASHI
IPC: H04B14/04
Filed: 1988-11-10
Abstract: PURPOSE:To realize a network including a repeating exchanging with a small quantity of a voice quality deterioration and the line exchanging accompanied by a voice band compression without having a complicated control circuit at an exchange side by identifying a signal from a terminal side input edge and controlling the activation and stopping of a voice band compression function by the result. CONSTITUTION:When a pattern identifying circuit 12 detects a signal pattern to specify that a voice band compression function is on, from a bit stream from a terminal side input edge 11, change-over switches 13 to 16 are switched to an A side and a voice band compressing circuit 17 is activated. When a signal pattern to specify that a voice band compression function is off is identified, the change-over switches 13 to 16 are switched to a B side, a signal from the terminal side input edge 11 is transmitted to a transmission line side input edge 19 and a signal from a transmission line side input edge 1A is transmitted to a terminal side input edge 1B in the condition of the universal multiplexed signal form. Thus, even without having the complicated control circuit at an exchange side, the network including the repeating exchanging with a small quantity of a voice quality deterioration and the line exchanging accompanied by the voice band compression can be realized.

Filed: 1986-11-28
Abstract: PURPOSE:To visually reduce the deterioration in a picture quality due to the difference of an interchannel characteristic by recording while switching the combination of each channel and a recording circuit and a head at every frame of a video signal. CONSTITUTION:A second channel switching circuit 14 has the same constitution as the first channel switching circuit of a recording system, and when a regenerated frame pulse is HI, the output signal of a reproducing channel CH1 is outputted to the output A, and the output signal of the reproducing channel CH2 is outputted to the output B, and when the frame pulse is LO, the output signal of the reproducing channel CH2 is outputted to the output A, and the output signal of the reproducing channel CH1 is outputted to the output B. Accordingly, the video signal CH.A is inputted to the input A of a channel composition circuit 15, and further, the video signal CH.B is inputted to the input B, and after being processed by a channel composing operation, the original video signal is obtained. Thus, because even if the difference of the interchannel characteristic occurs, the channel corresponding to each scanning line is switched alternately at every frame, the deterioration in the picture quality due to the difference of the interchannel characteristic can be reduced.

Abstract: PURPOSE:To obtain a variable wavelength laser having a wide controllable wavelength range by arranging a plurality of lasers having different output wavelength ranges on a single optical axis, and arranging a wavelength selecting mirror or a distributed reflection type waveguide on the extension of the axis. CONSTITUTION:Three lasers L1, L2, L3 having different optical output wavelength ranges are aligned through a condensing lens P on a common optical axis S.
