Title: Radio communication equipment
Inventor: OGI KOJI
IPC: H04B1/38
Filed: 1992-08-31
Abstract: PURPOSE:To avoid the useless occupancy of a frequency channel by providing a transmission circuit section, a reception circuit section, a transmission protection circuit and a control circuit controlling a transmission inhibit tentative release timer to the equipment so as to allow the transmission state for several seconds only even in the reception state during the operation of the transmission protection circuit. CONSTITUTION:With a transmission switch 7 closed, the reception state is switched to the transmission state, and when a temperature state passes through a preset heat point, a transmission protection circuit 6 is acted to select the reception state automatically. Even when the switch 7 is operated again after the release of the transmission switch and the circuit 6 is in operation, the transmission function is active by setting a short time. Then the transmission time by the transmission function is counted by a transmission inhibit tentative release timer 5 and the timer 5 expires over a prescribed time and the reception state is again restored.

Title: Level suppressing circuit
Inventor: IMAI KATSUMI
IPC: H03G11/00
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To prevent a signal waveform from being distorted even when an input signal is suppressed, by impressing the output signal of a comparator that level-compares the output signal of a feedback type differential amplifier with a reference value to a feedback resistance, automatically adjusting the output DC voltage of the feedback type differential amplifier for level- suppressing the input signal. SOLUTION: When the level of a signal generated at an output terminal 17 of a feedback type differential amplifier 10 is made high and close to a voltage V1 of a reference power source 19, the collector currents of a transistor 23 equal to currents running through a transistor 21 of a comparator 13 are allowed to run to a feedback resistance 11. The DC voltage of the output terminal 17 is decreased only for the voltage decrease of the feedback resistance 11. When the level of a signal generated at the output terminal 17 is made low and close to a voltage V2 of a reference power source 20, the collector currents of a transistor 24 equal to currents running through a transistor 26 of a comparator 14 are allowed to run from the feedback resistance 11. The DC voltage of the output terminal 17 is increased only for the voltage decrease of the feedback resistance 11.

IPC: G10L21/043
Filed: 1994-10-19
Abstract: PURPOSE: To reduce a processing load, to reduce deviation between a video and an audio and to prevent increase in memory capacity by speech speed conversion-processing an input audio signal with a speech speed conversion- processing means. CONSTITUTION: Since a ring memory 7 becomes easy to become an overflow just before state the more in a program whose vocalizing speed is faster, a compression rate is decided so that an audio reproducing speed becomes close to a double speed. On the contrary, the compression rate is decided so that the audio reproducing speed becomes close to a one time speed the more in the program whose vocalizing speed is later. Thus, the audio reproducing speed becomes the speed of the double speed or below and according to the original vocalizing speed, and a natural reproducing audio is obtained.

Title: Encoder
Inventor: INOUE KAZUHISA
IPC: G01D5/36
Filed: 1987-10-12
Abstract: PURPOSE:To reduce the influence of a DC component, to make a fast response, and to obtain a stable C-phase pulse by outputting a D-phase output which has the inverted waveform of a B-phase wave except at an origin position, and ANDing the B-phase output and D-phase output and outputting an origin signal. CONSTITUTION:For example, an optical encoder outputs A-phase and B-phase signals from a photodetecting element 4 through the rotation of a rotary disk 1. The D-phase output having the inverted waveform of the B-phase output is sent out at all times except at the origin position, and slits are coded so that the B-phase output is synchronized like only the origin position. Then an AND gate 5 ANDs the B-phase and D-phase outputs with each other to output an original pulse (C phase). Consequently, the slit code pattern is simplified and the stable origin signal containing a small DC component is obtained under various conditions.

Title: Image tube
Inventor: HOSHIYAMA TADASHI
IPC: H01J31/50
Filed: 1985-11-13
Abstract: PURPOSE:To prevent production of a false signal due to reflection at an incident window, so as to improve the contrast of an output image by specifying the thickness of the light incident window while applying a block film for preventing reflection onto the circumferential section of the outer face and the side wall section except the effective area of a light incident window. CONSTITUTION:A light incident window 1 has the thickness (d) larger than 1/3 of the effective diameter (L) of a photoelectric face 2 while a black film 8 is applied onto the circumferential section and the side wall section except the effective area of the outer face. A beam of light reflected with a full- reflection critical angle theta from the photoelectric face 2 onto the outer face of the light incident window 1 is fully reflected, but arrives again at the photoelectric face in such position as separated by a distance of 2d.tantheta from the initial point. Since the critical angle theta is about 42 deg. when the light incident window is made of glass, the reflected light 9 will scarcely be incident again on the effective area of the photoelectric face 2 in case of such image tube as constructed to satisfy the relation 3d.tantheta>L, but arrive at the outer edge section where it will be reflected again to be incident finally on the black film section 8 and absorbed there.
