Title: Infrared pyrometer
Inventor: YAMAGUCHI YUKIO
IPC: G01J5/08
Filed: 1986-11-19
Abstract: PURPOSE:To automatically measure brightness temp. even when the temp. of a heat generating body is low, by mounting an image intensifier tube (IIT) having sensitivity to infrared rays and a radiation thermometer using an infrared ray detector. CONSTITUTION:IIT 9 integrally forms the image of a heat generating body and a reticle for comparing reference on the photoelectric surface thereof. The photoelectric surface of IIT 9 also has high sensitivity to near infrared rays and converts said infrared rays to a photocurrent. The photocurrent is amplified by the secondary electron multiplying type multichannel plate incorporated in IIT 9 to allow the fluorescent surface present on the opposite side of the photoelectric surface to emit light and the image on the photoelectric surface is increased in its intensity by several ten thousand times to be allowed to brightly emit light. Then, the current of a lamp 5 is adjusted so as to add the brightness of the reference reticle to that of the image of the heat generating body and the temp. of the heat generating body can be measured by reading the current of the lamp. Next, when a light path is changed over by a reflecting mirror 2, the image of the heat generating body is formed on an infrared ray detector 11. The output of the infrared ray detector 11 is amplified by an amplifier 12 to be displayed on a radiation temp. display device.

Title: Ignition control system of internal combustion engine
Inventor: SASAKURA HACHIRO
IPC: F02P5/15
Filed: 1992-10-15
Abstract: PURPOSE:To control the ignition energy required for applying power to an ignition coil (the power application time of the ignition coil) corresponding to the discharge voltage of an ignition plug. CONSTITUTION:Ignition timing (advanced value) is calculated on the basis of the speed NE of an internal combustion engine, the quantity QN of intake air and cooling water temperature TW (310, 320). Next, a correction factor for setting the power application time of an ignition coil shorter as the ignition timing is advanced is calculated (330) and the power application time of the ignition coil is calculated on the basis of the engine speed NE and battery voltage VB (340). It is then determined whether or not the speed of the internal combustion engine is high (350), and when the engine speed is not high the power application time is shortened by using the correction factor, whereas when the engine speed is high the power application time is not corrected. Finally, the ignition timing and the power application time are set as power application control parameters for the ignition coil (370) and (310) is reentered. By the above process the power application time can be made to correspond to the discharge voltage of an ignition plug and the rate of consumption of the energy required for ignition can then be reduced.

IPC: H01L21/205
Filed: 1986-11-21
Abstract: PURPOSE:To be able to perform an impurity doping control without crystal distortion by vapor growing metal compound gas containing radioisotope of a crystal constituent element and transferring it to an impurity by the nuclear decay of the radioisotope. CONSTITUTION:When a semiconductor crystal layer is formed by a vapor growing method (MOCVD method) using metal compound gas, organic metal compound gas containing radioisotope of constituent element of a crystal to be grown is used, a crystal growth is executed, and it is transferred to an impurity by the nuclear decay of the radioisotope. Since the element of the semiconductor crystal and its radioisotope do not have difference in atomic radius and ion property. Accordingly, even if the crystal growth is performed with metal compound containing the isotope, no disorder occurs in a crystal lattice. When it is transferred to the impurity due to the nuclear decay of the isotope, it is not displaced from the lattice point, no crystal distortion occurs different from the case that the impurity is forcibly doped from externally. Thus, deep impurity level is not formed, n-type impurity doping can be easily controlled.
