Title: Accelerator control device for crane
Inventor: TAKASHIMA TOMOHIRO
IPC: B66C13/56
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To perform accelerator operation by an accelerator cylinder, even in manual operation by providing a detector for detecting the operation amount of a crane control lever, and providing a control part for driving the accelerator cylinder on the basis of the detection signal of this detector. SOLUTION: A potentiometer 6 for detecting the rotating amount of a vertical shaft 12L is provided on the lower end of the vertical shaft 12L, and the operating amount of a crane control lever 8R is detected as the rotating amount of the vertical shaft 12L. The expansion and contraction of the piston rod 27 of an accelerator cylinder 26 is controlled by the drive signal outputted from a control box 30, on the basis of the detection signal of the rotating amount of the vertical shaft 12L from the potentiometer 6 and the accelerator operation signal from a remote control means. According to this, since the accelerator operation can be performed by use of the accelerator cylinder 26 when the accelerator is manually controlled by the crane control levers 8R, 8L, the operating force can be reduced.

Title: Programmable monolithic integrated circuit
Inventor: MASUDA HAJIME
IPC: G11C17/08
Filed: 1980-03-25
Abstract: PURPOSE:To enable a P-N-P-N circuit to turn on normally when P-ROM increases in capacity and the number of P-N-P-N circuits also increases, by flowing a small current to bases of N-P-N transistors of the P-N-P-N circuit constituting a writing circuit. CONSTITUTION:For example, gates 1 and 3 of column selecting circuit 22 of the decoder composed of diode matrix 30 and gates 1... are held at the high level, and gates 2 and 4 at the low level, selecting the P-N-P-N circuit of transistors Q2 and Q3. So that a minute current will flow the base of N-P-N transistor Q3, a voltage high enough to turn on Zener diode D1 of applying circuit 24 is applied, and then the minute current flows from the base to the emitter of transistor Q3 and then to a memory cell. Next, flowing a write current from write terminal W turns on the P-N-P-N circuit easily because transistors Q2 and Q3 of the selected P-N-P-N circuit are activated, so that even when P-ROM increases in capacity and the number of P-N-P-N circuits also increases, the P-N-P-N circuits is turned on normally.

Title: Method for reducing radio wave attenuation by three polarized waves
Inventor: UMEHARA TADATOSHI
IPC: H04B7/10
Filed: 1987-02-23
Abstract: PURPOSE:To reduce the attenuation by a transmission medium by transmitting a linearly polarized wave and another linearly polarized wave in opposite phase to the polarization direction of the former linearly polarized wave and having different polarization direction by 45 deg. after synthesizing them. CONSTITUTION:A linearly polarized wave having different polarization direction by 45 deg. from the polarization direction of a linearly polarized wave I is generated and the waves formed in opposite phase to the linearly polarized wave I are formed as linearly polarized waves II, III. Then the linearly polarized waves II, III are brought into 1/2<1/2> or below the linearly polarized wave to reduce the synthesized wave of the linearly polarized waves I, II and III. Since the loss is proportional to the square of the synthesized electric field, the polarization direction of the linearly polarized waves II, III is rotated by receiving the electric field by the polarized wave rotating device after being transmitted through a transmission medium with a long distance and small attenuation, and the waves are synthesized in opposite direction to the linearly polarized wave I, but since there is a difference in the phase speed of the linearly polarized waves I, II, III, the synthesized wave of a filtered wave is increased.

Title: Light guide
Inventor: HORIKOSHI KAZUTOMI
IPC: G02B6/04
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To heighten the bendability of a light guide formed by an optical fiber bundle and to make the guide hard to be broken even when its diameter is seduced. SOLUTION: A light guide inserted in an endoscope is formed by binding resin-made optical fibers 10a, and the light guide is covered except at least a portion thereof positioned in a curved part 3e of the endoscope. An optical fiber bundle is formed by binding plural first optical fibers, and plural second optical fibers having a diameter larger than that of the first optical fiber are arranged in the periphery of the optical fiber to form a reinforcement layer. Thus, the filling rate of the curved part of the endoscope is lowered, so that load applied to the light guide caused by bending the curved part is lightened to prevent breakage of the optical fiber and prolong the life of the light guide and the endoscope.

Title: Radar device
Inventor: YAMADA HIDEO
IPC: G01S7/02
Filed: 1981-03-17
Abstract: PURPOSE:To measure accurately the altitude of a low altitude flight, by limiting the range of elevation scanning of radio beams to an angular range which is determined preliminarily in accordance with the bearing. CONSTITUTION:The bearing signal from a three-dimensional radar is counted, and this count value is compared with the bearing which is stored perliminarily in accordance with topography; and if they coincide with each other, elevation information corresponding to the map bearing is outputted to an antenna scanning controller. Elevation scanning is performed on the basis of this information to calculate an accurate altitude value. Thus, an accurate altitude value of a target is obtained in all bearings while setting of the tilt angle of the antenna is fixed.
