Title: Preparation of column for chromatogram
Inventor: KURODA KOUJI
IPC: G01N30/52
Filed: 1980-11-29
Abstract: PURPOSE:To prepare a titled stable column having high packing density and high efficiency, by expanding the diameter of a tubular material made of cross- linked high molecular thermoplastics by heating and packed with the filler in it and after that, fixing the filler by carrying out the shrinking deformation. CONSTITUTION:A high molecular thermoplastic material such as ehtylene-vinyl acetate copolymer containing 15-40% vinyl acetate is formed in a tubular shape having a diameter (0.5mm.-50cm) smaller than a prescribed inner diameter, then cross-linked by irradiating 1-60 Mrad radioactive rays. Next, after this formed body is plasticized by heating and its diameter is expanded and cooled to a temperature losing the plasticity, the filler for chromatogram is packed in the formed body and packings for an entrance and exit are arranged on both ends of the formed body and shrinking deformation of the formed body is carried out by heating to fix the filler in the formed body. Hereby, the space is not left be tween the surface of a wall of a column and the filler and stable and highly efficient separation can be achieved because the filler and the surface of the wall of the column is stuck closely.

Filed: 1985-08-01
Abstract: PURPOSE:To improve blue color sensitivity by a method wherein ions are implanted in such a manner that the ratio dox/Rp of the thickness dox of an oxide film to the projected range Rp is controlled to be 0.9-1.5 in manufacture of an MOS-type image sensor. CONSTITUTION:A field oxide film 6, a gate oxide film 7 and a polycrystalline silicon layer 8 for a gate electrode are formed on a P-type substrate 1 and ion implantation is carried out to form a source region 10 and a drain region 11 with self-alignment.

Title: Charge controller for vehicle
Inventor: ATSUMI HISAYUKI
IPC: H02J7/16
Filed: 1987-07-08
Abstract: PURPOSE:To improve acceleration performance of a vehicle, by judging whether a vehicle is accelerated abruptly based on a negative pressure in an intake tube and stopping recharging of a battery through a generator if the vehicle is accelerated abruptly, thereby enabling judgement of abruptly accelerated state through a simple structure. CONSTITUTION:An alternator 10 is driven through an engine 12. Output voltage from a stator coil 18 is rectified through a main rectifier comprising diodes D1-D6 and employed for recharging a cell 16. During abrupt acceleration where a throttle valve 20 is fully opened, output from a negative pressure sensor 24 for detecting negative pressure in an intake tube lowers, and a judging circuit 26 outputs a recharge stopping signal having positive voltage. Consequently, a transistor C is turned OFF to stop generation of power through the alternator 10 so as to reduce engine 10 load to be born by the alternator 10.

Title: Synchronous mechanism of transmission
Inventor: HASEGAWA HIDEO
IPC: F16D23/06
Filed: 1980-11-28
Abstract: PURPOSE: To prevent generation of noises at the time of a car starting by providing the synchronized meshing mechanism with a energizing means to be in operation in idling and thereby eliminating backlash of the speed change gear at the time of idling.  
     CONSTITUTION: When a coupling sleeve 38 is shifted, a balkring 39 or 40 makes slide contact with a conical surface 42 and applies thereby a braking effect, and a further shift will consolidate the main shaft with a speed change gear 34 or 35. At this time a press pin 44 is set in a cup ring sleeve 38, and because this  pin 44 works at the time of idling to press the balk ring 40 against the cone 42 with the aid of a spring 47 and a ball 48, backlash is eliminated. Because the ball 48 is brought up outwards by centrifugal force while the main shaft is in rotation even through the speed change gear is set in the neutral position temporarily during running, no backlash elimination is made.

Filed: 1992-06-26
Abstract: PURPOSE:To minimize the effect on the entire system by counting the number of times of a fault in the loopback operation by a loopback diagnostic means, outputting an error signal when the count reaches a prescribed value and stopping the transmission reception function of itself. CONSTITUTION:When a receiver 22 is faulty and the reception is disable, a communication control means 10 commands the diagnosis of a transmission reception function of itself to a loopback diagnostic means 31. The means 31 sends a communication frame to a communication line BS to diagnose whether or not the frame is correctly received. When the frame cannot be received due to a fault of the receiver 22 as the result of diagnosis, a loopback error signal is outputted to a counter 32. When the count of the counter 32 reaches processing value, an error signal is outputted to a transmission reception operation stop means 33 and the means 33 commands the stop of the transmission reception to disconnect a communication controller CS from the line BS. Thus, the effect on the entire system is minimized.
