Filed: 1988-06-27
Abstract: PURPOSE:To obtain a MOS transistor where the occurrence of short-channel effect and punch through are restricted by cladding a platinum layer on a single- crystal silicon substrate selectively and allowing it to be subject to heat treating within an environment containing no oxygen. CONSTITUTION:When an oxide film at the gate area is eliminated after a thermally oxidated film 12 which is 200Angstrom  in thickness is formed on the surface of a silicon substrate 11, a platinum layer 13 is clad on it to a thickness of 400-600Angstrom  by sputtering, and heat treatment is performed within an environment with a ratio of argon 7 and oxygen 1, a platinum silicide layer 14 which is 800-1200Angstrom  in thickness is formed and an SiO2 film 15 which is approximately 100Angstrom  in thickness is formed between a layer and a substrate silicon. Then, it is boiled in an etching solution of nitric acid and hydrochloric acid to eliminate non-reacted platinum and ion implantation for forming an S/D area is performed. Implantation energy is selected to allow an S/D area 16 which has nearly the same depth as that of the gate insulation film 15 to be formed after activation processing. As a result, with a simple processing, gate structure can be formed in embedded type so that a MOS transistor where occurrence of short-channel effect and punch through are restricted can be easily obtained.

Abstract: PURPOSE:To reduce the hysteresis of a step motor and to improve the positional precision by stopping the motor after it is reciprocatingly driven with the target stop position as the center and within the limits not too large. CONSTITUTION:When no STEP signals are inputted, two phase signals in total, i.e., either phiA or phiC and either phiB or phiD, are fixed as the signals to be driven finally.

Title: Energization-controlling circuit for thermal head
Inventor: UMEHARA NORIO
IPC: B41J2/36
Filed: 1986-07-07
Abstract: PURPOSE:To constantly obtain a uniform printed density, by controlling the width of energizing pulses according to the number of heat generating resistor elements energized. CONSTITUTION:The period of time required for an output from a comparator 10 to become high after an energizing signal 6 becomes high is inversely proportional to the number of resistors 14 for discharging a capacitor 12. The number of the resistors 14 is equal to the number of heat generating resistor elements 1 simultaneously supplied with energizing pulses. Therefore, when the period of time for which the energizing signal 6 is high is maintained to be constant, the width of the energizing pulses is longer as the number of the heat generating resistor elements 1 simultaneously supplied with the energizing pulses is greater. The lowering in a printed density due to a lowering in the voltage of the energizing pulses with an increase in the number of the heat generating resistor elements 1 simultaneously supplied with the pulses is corrected by the control of the width of the pulses, and a uniform printed density can be obtained.

Abstract: PURPOSE:To obtain a method and an apparatus for general-purpose packing which can pack easily by applying vibration to a table with a flexible heavy object mounted, moving it in a certain direction and moving a sheet packing material in the reverse direction. CONSTITUTION:An object 1a to be packed is mounted on a table 10, and with a cylindrical packing material 20 made of resin wound around a beam 21 prepared on an end of the table, air is supplied to open its opening. A next object 1b to be packed is carried by using a heavy object carrier 30 or the like to the other end. When a vibrator 11 is driven, vibration is applied to the table 10 and the object 1a, so that the object momentarily comes off a surface of the table 10 to float. Since the table surface 10 is gradient, the object gradually goes forward toward an arrow A. When a tip 20a of the packing material 20 is inserted between the object 1a and the table 10 surface, the material 20 naturally goes in the reverse direction to the object 1a. A heat-fusing mechanism is used to fuse both ends of the object.
