Title: Automatic navigating device
Inventor: AKAMATSU AKIO
IPC: G01C21/00
Filed: 1981-06-03
Abstract: PURPOSE:To prevent a delay of control in navigation when a ship approaches a prescribed, course and to prevent the ship from a danger when a course deviation output is suddenly changed, by changing the output slowly when the course deviation is sharply changed and quickly in case of small course deviation. CONSTITUTION:If course deviation voltage suddenly falls to zero when a ship is sharply deviated from a set course, Zener diodes D1, D2 are made conductive eletrically and the charge of a capacitor C charged through a series circuit consisting of the capacitor C and a resistance R2 is gradually turned to zero. Consequently, the safety of the ship is maintained without the sudden change of a rudder. When the ship is not deviated so much from the set course, the Zener diodes D1, D2 are made nonconductive, and the capacitor C is separated from a time constant circuit. Thus, the voltage change of a course deviation operating circuit 10 is applied to an adder 5 without delay.

Filed: 1995-03-17
Abstract: PURPOSE: To provide a gallium nitride compound semiconductor light emitting element, which improves its luminous intensity. CONSTITUTION: A multiple quantum well structure (MQW) has a structure, wherein a well layer 52 is encircled with large-band gap layers, which are used as barrier layers 51, on both sides thereof, most of carriers generated in the layers 51 flow in the layer 52 and contribute to a light emission. Therefore, the luminous intensity of the light emitting element is improved and an output of the element is increased. Here, when an acceptor and a donor are simultaneously added to the layer 52, there is a longer wavelength light emission between the acceptor level and the donor level in the layer 52 and as there is a large amount of carriers in the layer 52, the luminous intensity is maintained high.

Title: Heating device and image forming device
Inventor: FUKUZAWA DAIZO
IPC: G03G15/20
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent temperature fall at the end of a heating body and also to prevent the damage of a heater by making an energizing heating element oppositely press-contact with a pressure member all over the area in a longitudinal direction and making the calorific value of the heating body larger at the end than at a central part. SOLUTION: The length in the longitudinal direction of a pressure roller 9 is longer than that of the heating element 3, so that the heating element 3 does not project to the outside from the end of the roller 9. Namely, the heating element 3 of the heater 1 is opposed to the roller 9 in all the area. The width of the heating element 3 is narrowed at the end. By energizing the electrode for energizing 11 of the heater 1, the heating element 3 generates heat, and the calorific value of each part of the heating element 3 is proportioned to RI<2> at such a time. Therefore, high resistance parts B at both ends in the longitudinal direction generates much more heat than a low resistance part A at the central part in the longitudinal direction. Thus, temperature distribution in the longitudinal direction in an overheat nip formed by the heater 1 and the roller 9 is made uniform.

Abstract: PURPOSE:To reduce manhours required for bonding work and prevent erroneous insertion of pins having different length by previously arranging the pins, and simultaneously inserting or detaching the plurality of pins into or from through holes formed on a base plate when a stud is bonded to the through hole. CONSTITUTION:A fixing part 2 is arranged in such a manner as to be erected right at a surface 10A of a frame 10, In bonding, a base plate 1 is superposed on the frame 10, and then, the pin 5 is inserted into a through hole 3 formed on the base plate 1. Upon completion of bonding, the frame 10 is detached from the base plate 1, and the pin 5 is drawn out of the hole 3. At this time, since a stud 4 comprising a head portion 4A, a flange portion 4B, an insertion port 4C and an inner circumferential surface 4D is fixed by a ring solder 6, there is provided a spring 11 on the bottom surface of the fixing part 12, thereby facilitating the drawing-out of the pin 5. Consequently, it is possible to eliminate troublesome inserting/detaching work of the pins 5 one by one before/after the bonding work, thus reducing manhours.

Abstract: PURPOSE:To provide a method for sensing salinity related to metal corrosion or drop in electric resistance of an insulator, etc. CONSTITUTION:A sensing light flux Le is incident to a prism 1, after being reflected in the prism a plurality of times, the flux is taken out of the prism 1, and then it is again incident to the prism 1 and reflected to be taken out of the prism 1. After the cycle has been repeated by an appropriate number of times subsequently, a light amount of a finally emitted light flux Lo emitted from the prism 3 finally is measured by a light power meter 7, and the output is compared with the sensing light flux Le which was first incident to the prism 1. In this cycle, reflection points R1, R2, R3,... of the sensing light flux Le in the prism 1 is sequentially shifted per cycle. An attenuation ratio of the finally emitted light flux Lo to the sensing light flux Le which was first incident to the prism 1 is measured, whereby an amount of salt attached to salt attaching faces A1, A2 on outer faces of prism reflecting faces P1, P2 can be known. Especially by repeating the above cycle, even if an amount of existing salt is very small, it can be sensitively sensed.

Title: Multi beam light modulation deflector
Inventor: IOKA AKIO
IPC: G02F1/33
Filed: 1978-07-14
Abstract: PURPOSE: To prevent light from nonlinear modulation and deflection by use of synthetic signal free from locally large amplitude, plural HF signals are phase controlled and ultrasonic light deflector is driven in parallel.  
     CONSTITUTION: In a driving system 4, parallel connected modulation circuits 5B, 6B,... are connected to phase control oscillator circuit 5A, 6A... such as PLL oscillators. Thus, each HF signal from the circuits 5B, 6B,.. are independently controlled for synthetic HF signal to be immune from locally large amplitude which occurs when each HF signal phase agrees. Accordingly, the amplifier 14 output is free from nonlinearity due to saturation of locally large amplitude. Thus the audiooptical element 3 controlled by the amplifier 14 linearly modulates and deflects laser from the source 1, providing high-speed and good-quality laser modulation and deflection.

Abstract: PURPOSE:To obtain a high quality amorphous film with a minimized number of damages by a method wherein projecting electrodes are provided on the surface of a sample board such that the electrical field is concentrated on the projecting electrodes. CONSTITUTION:A plurality of projecting electrodes 5 are, at proper spacings, provided on the surface of a sample board 2 facing a flat-plate electrode 1. A sample 6 to be treated is mounted on the sample board 2 between the projecting electrodes 5 for the purpose of growing an amorphous film.

The surface of the sample 6 is directly, therefore, not exposed to the plasma. Growth nucleus obtained by the decomposition of a silane gas in the plasma reaches the surface of the sample 6 by virtue of the electrical discharge, and a film is quietly grownh as if falling snow are accumulated. The ions and electrons existing in the plasma in no way exert any damages to the surface of the sample, thereby to obtain high quality amorphous film with a reduced number of defects.
