Title: Trouble shooting method for automobile
Inventor: MASUDA YUTAKA
IPC: G07C5/08
Filed: 1980-09-06
Abstract: PURPOSE: To provide possibility of knowing before commencing car drive if any trouble exists in the mechanism by furnishing the car with a trouble diagnosis system which judges the conditions of every part one after another with the aid of a builtin computer after the engine is started and emits a necessary alarm automatically if it senses any part being out of order.  
     CONSTITUTION: Turning on the main switch 30 will permit the CPU14 to light up an alarm lamp 22 and all indicator lamps 20aW20h and also to check itself how it is in condition. When the engine is started and the output voltage of an AC generator 24 continues for the period a in sends or longer, the system is put into the scanning process, that is to extinguish the indicator lamp after the time b in seconds one after another if the parts are in good condition and keep the corresponding lamp lighting if any part is out of order until the switch 30 is turned off, and also to allow the alarm lamp 22 to twinkle. When the whole scanning process is completed, the system is turned into normal monitoring, but turning on the check switch 28 can let the system repeat the scanning process as above whenever the driver wants.

Title: Lens mount mechanism
Inventor: ISHIKAWA KENSAKU
IPC: G03B17/14
Filed: 1987-05-22
Abstract: PURPOSE:To quickly replace the prescribed lens by providing on a camera main body side with an automatically turnable and resettable mounting member which is press-turned by a fan-shaped projecting claw on a lens side. CONSTITUTION:When a lens main body 1 is pushed in toward its optical axis P to fit an engagement regulating groove 6 provided on the law 4 of the lens main body 1 into a pin 16 studded on the side of the camera main body 11, a slope 5 and a moved slope 15 which abut on and closely contact with each other enable the pushing-in force to act as component force on the turnable mounting member 12. The moved slope 15 smoothly moves on the slope 5. As soon as the slope 15 passes through their contact area, the lens main body 1 is further put into the side of the camera main body 11. Then, returns and turns the mounting member 12 under the energizing and returning force of a coil spring 18, and each locking projection part 24 alone stays in front of each claw 4 of the lens main body 1, which is held. Thus the single operation that the lens main body is pressed into the camera main body enables the quick replacement and loading of the prescribed lens.

Title: Surface treatment of aluminum or alloy thereof
Inventor: HIRAI MASATOSHI
IPC: C25D11/12
Filed: 1982-07-15
Abstract: PURPOSE:To form a colored film having vitreous deep gloss feeling on the surface of Al (alloy), by a method wherein Al (alloy) is subjected to primary electrolytic treatment in a sulfuric acid bath and the treated one is further subjected to secondary electrolytic treatment in a chromic acid bath to the subsequently dyed with a dye. CONSTITUTION:Al or an Al alloy is subjected to primary electrolytic treatment in a sulfuric acid bath. The treated one is subsequently subjected to secondary electrolytic treatment in a chromic acid bath to form a chromic acid film to the interfacial layer of the sulfuric acid film and Al. In this case, chromic acid erodes the sulfuric acid film to enlarge the pore gap of the film. Therefore, in dyeing the treated Al or the Al alloy with a dye, the precipitation amount of the dye is increased and a colored film having vitreous deep gloss feeling is obtained.

Title: Preparation of silicon single crystal
Inventor: ENOKI SHIGEO
IPC: C30B29/06
Filed: 1982-07-16
Abstract: PURPOSE:To obtain a single crystal whose carbon impurity concentration is accurately limited to a given value, by melting a polycrystalline raw material in an inert gas atmosphere, reacting it with a carbon-containing gas before it is completely melted, melting it completely, pulling up a single crystal rod. CONSTITUTION:A polycrystalline silicon raw material is put in the quartz crucible 2 in the furnace 1, electricity is applied to the graphite heater 4 while an inert gas is introduced from the inlet 7 at the top of the furnace to it, and the polycrystalline silicon is melted under heating. Before the silicon raw material is completely melted, a fixed amount (flow rate X time) of a carbon-containing gas such as CO gas is introduced from the inlet 8 at the top of the furnace to it, and it is reacted with the silicon raw material melt 9. After the reaction is over, the silicon raw material is completely melted, the temperature of the melt is lowered to the seed contact temperature, and a single crystal rod is pulled up by the seed crystal 5. Consequently, the carbon impurity concentration in the silicon single crystal can be securely controlled.

Title: Analyzing method for hydrogen atom contained in semiconductor crystal
Inventor: MOCHIZUKI YASUNORI
IPC: G01N21/63
Filed: 1992-05-18
Abstract: PURPOSE:To nondestructively measure the charged state of hydrogen atoms when they are diffused in a semiconductor crystal and determine the concentration by analyzing the luminescence intensity change for various pairs having different separation distances after making the donor/acceptor pair luminescence spectrum measurement. CONSTITUTION:The donor/acceptor pair luminescence spectrum measurement is made before and after hydrogen is introduced, thus the charged state of hydrogen in the crystal is nondestructively determined, and the concentration is measured in the analyzing method of the hydrogen atoms contained in the semiconductor crystal. A laser having the absorption coefficient of as large as 10<5>cm<-1> or above at the oscillation wavelength as an exciting light source is used, and only the vicinity of the semiconductor surface where hydrogen is diffused is set to the measurement object area. The distance (r) at which an abrupt change occurs in the pair separation dependency of the luminescence intensity change due to the introduction of hydrogen is measured. This abrupt change occurs when the distance between a donor and an acceptor coincides with the average distance between purities and hydrogen atoms, and the hydrogen atom concentration N can be calculated from the relation of N=1/(2pir<3>).
