Title: Focus detector
Inventor: SUZUKI KENJI
IPC: G02B7/34
Filed: 1982-09-20
Abstract: PURPOSE:To obtain a compact, high-precision focus detector by arranging a secondary image formation system behind a photographic lens and forming successively distributed visual-field images, and detecting distributed images in the effective photodetection area of a photoelectric element and deciding on a focusing state. CONSTITUTION:Light projected from one light point passes through the photographic lens 31, a visual-field mask 32, a field lens 33, a deflecting prism 34, and a secondary image-formation lens 35 to form images on the photoelectric element array 36. In a focusing state, a belt with wide light hole width is formed on a light perpendicular to the lengthwise direction of the images. In a defocusing state, a slanting belt is formed because light beams have parallax mutually. The output signal of the photoelectric element array 36 is processed to decide on the focusing state. Consequently, the compact, high-precision focus detector is obtained.

Title: Confirming device of position for moving body
Inventor: TAKEBE KATSUHIKO
IPC: G01C21/00
Filed: 1982-09-20
Abstract: PURPOSE:To confirm the position of a communication partner easily and accurately by mounting a device which calculates the position of a moving body such as an automobile on two-dimensional coordinates momentarily while detecting variations in the distance from the starting point of the movable body and its direction, and displays the current position on a display device where the map of a movement expected area is set previously. CONSTITUTION:When the moving body starts running, a one-pulse signal is sent from a distance detector 1 to a signal processor 3 at every interval of unit run distance and the number of pulses is counted to measure the run distance; and the output of a direction detector 2 is also sent to the signal processor 3, which decides on the movement direction of the moving body momentarily. The signal processor 3 calculates the current position (x, y) on the X-Y coordinates according to the reduction rate of the preset map on the basis of variations in the detected distance and direction of the moving body, and sends the arithmetic result to the display device 7 and a movement track storage device 4, where it is stored and held. Its storage contents are read out all the time and sent to the display device 7 successively.

Title: Heating device of ink jet printer
Inventor: ISHIKAWA CHIYUUJI
IPC: B41J2/195
Filed: 1982-09-20
Abstract: PURPOSE:To enhance the increase speed of ink temperature by a construction wherein a heating device includes a housing having a heating means on its outer periphery and a bush inserted in said housing and a groove is formed on the inner periphery of the housing or on the outer periphery of the bush. CONSTITUTION:A bush 26 having a thread groove on its outer periphery is inserted into a liquid chamber under a low pressure. In this case, since the bush occupies the liquid chamber, no pressure gradient is produced in the ink. The ink injected by a pump travels toward the outerside of the bush 26 and flows along the lead of the thread groove. The thread groove portion where the ink flows has a comparatively high temperature since it is located near to a heating device. The ink flows along the thread groove having a higher temperature. The portion contacted the heating device is long. A resin material having a heat resistance and a poor heat conduction may be used as the bush.

Abstract: PROBLEM TO BE SOLVED: To simulation run a vehicle conforming to a running state of the vehicle without a sense of incongruity by setting a speed change means for changing a pseudo-running speed on the basis of road attributes of a road where the vehicle conducts a pseudo-running. SOLUTION: A point A where a vehicle is positioned when a driving simulation starts is set to be a first vehicle position of a pseudo-run. A vehicle position mark is plotted to the vehicle position of the pseudo-run on a map image. A vehicle mark is plotted to a pseudo-vehicle position on the map image read out from a map database 14 and plotted. The vehicle mark is stored in an image memory in a control part 2 and at the same time displayed to a display part 31. An attribute of a road where the vehicle falsely runs is detected, and road attributes (a road type, a limiting speed, a width) of a point where the vehicle is falsely running is read out from the map database 14.  The map image including the vehicle position which moves with a distance interval corresponding to a pseudo-running speed is sequentially updated and displayed at intervals of a constant time in accordance with whether the road is a road of fast road attributes or whether the road is a road of slow road attributes.

Title: Amplifier
Inventor: KOBAYASHI TOSHIMITSU
IPC: H03G3/20
Filed: 1990-06-22
Abstract: PURPOSE:To prevent adverse effect on other amplifier units by interrupting a power voltage of an amplifier unit when a signal through a diode is interrupted at the stop of the amplifier unit and starting application of power voltage before the diode reaches the signal conduction state at restart. CONSTITUTION:Amplifier units 151-15m are not stopped by simply turning off a power voltage. That is, an amplifier unit to be stopped is disconnected one by one from other amplifier units by using a switch of the amplifier unit to be stopped among switches 131-13m and 161-16m and then the power supply is interrupted. When an amplifier unit is started again, the power voltage is not simply applied, but after the start of application of the power voltage, the amplifier unit is gradually connected (in the case of use of a diode). Thus, adverse effect on other amplifier units is minimized in the stop of the amplifier unit and in the stop of restart.
