Title: Optical demultiplexer
Inventor: HAGIWARA KIYOKAZU
IPC: G02B6/293
Filed: 1985-07-02
Abstract: PURPOSE:To constitute an optical demultiplexer in an extremely simple shape by using a plane curved diffraction grating. CONSTITUTION:Curved diffraction grooves are formed in the surface of the plane transmission plate of a dielectric 1 where the plane curved diffraction grating is formed so as to have light converging effect. An end part of an optical fiber 3 is inserted into a recessed part formed in one end surface of the dielectric 1 where the plane curved diffraction grating is formed. End parts of optical fibers 4, 5, 6, 7, and 8, on the other hand, are inserted into recessed parts formed in one end surface of a transparent prismatic dielectric 2 and the dielectrics 1 and 2 are jointed together by using a material whose refractive index is nearly equal to that of the optical fibers. Light having five different wavelengths is made incident on the plane curved diffraction grating from the input optical fiber 3 through the dielectric, and than this light is wavelength- dispersed and reflected at different angles corresponding to the wavelengths, and also converged by the plane curved diffraction grating 1, so that light beams having the mutually different wavelengths are photodetected by the output optical fibers 4, 5, 6, 7, and 8.

Title: Bar-graph display unit
Inventor: AKAMATSU KENZOU
IPC: G09G3/04
Filed: 1978-11-24
Abstract: PURPOSE: To reduce the power consumption and to display by a bar-graph by arranging the display elements in the form of matrix and by lighting a fixed number of elements according to the input voltage.  
     CONSTITUTION: An input signal is AD-converted and fed to the decorders 2, 3 outputs of which drive the fixed lines of X and Y sides of the matrix display panel composed of LEDs. The switching elements at the intersections of X and T lines are controlled to light all LEDs of number less than the intersection LED number. For example, when output 5 of the decoder 2 and outputs 10W19 of the decoder 3 are obtained, LEDs 8-15W8-0 are all lighted. The number of lighted LEDs is proportional to the input voltage applied to the A-D converter 1. As a result, a bar-graph can be displayed according to the input voltage.

Title: Inverter device
Inventor: UNNO MASATO
IPC: H02M7/515
Filed: 1983-08-10
Abstract: PURPOSE:To prevent the commutation failure by clamping the output voltage of a comparator to a lower value than the normal case when a power source voltage drops.

Title: Laser device
Inventor: TAKEHISA KIWAMU
IPC: H01S3/08
Filed: 1990-06-06
Abstract: PURPOSE:To reduce a local temperature rise and improve conversion efficiency by mounting a parallel plate with a laser device so that it may be rotated where? CONSTITUTION:A normal line of a parallel plate 11 is provided with an angle separated from the incident direction of laser light. Therefore when the laser light enters the plate 11, the reflection of the light forces the discharge direction of laser light in parallel to the direction prior to the incidence, but produces positional shift. When the plate 11 is rotated, the shift direction is also rotated. To comply with this, non linear optical devices or solid laser mediums are placed in a passage of light subjected to the shift, the position on which the laser light shines is rotated, making a picture of circular orbit so that the area subject to the laser light may be dramatically extended, which inhibits a rise in the temperature of devices or mediums induced by the heat f the laser light and hence minimizes the degree of unequal temperature distribution. Furthermore, this construction does not lower the intensity of laser light which enters non-linear optical devices, thereby preventing the conversion efficiency of frequency increase or excitation efficiency from being lowered.

IPC: B60H1/00
Filed: 1982-08-25
Abstract: PURPOSE:To prevent the corrosion of an evaporation, the clinging of soot and the decomposition of a coolant and refrigerating machine oil in an air conditioner of heat pump type which employs the exhaust heat of an engine, by using a rotary heat exchanger to perform heat exchange between the exhaust gas of the engine and intake air to conduct the heated air to the evaporator. CONSTITUTION:Exhaust gas S2 is introduced into a rotary heat exchanger 23 from an exhaust pipe 25. Air S4 is introduced into the heat exchanger from an air duct 22. Heat exchange is effected between the exhaust gas and the air. When the S4 is not introduced into the heat exchanger 23, the exhaust gas S2 is discharged as scarcely-changed gas S3 and room heating is not effected. When the air S4 is introduced into the heat exchanger, the heated air S5 is delivered to an evaporator 25 so that the air is further heated and then released into the riding room of a vehicle to heat the room. Since only the clean air flows through the evaporator 25, it does not corrode, no soot clings thereto and a coolant etc. are not decomposed. The capacity of air conditioning can easily be adjusted by controlling the revolution speed of the heat exchanger 23.
