Title: Manufacture of mos transistor
Inventor: YAMAKAWA MASAKI
IPC: H01L21/265
Filed: 1988-09-21
Abstract: PURPOSE:To form an offset region without damaging source/drain regions by forming a thermal oxide film on a polysilicon gate electrode and by forming the offset region utilizing this thermal oxide film. CONSTITUTION:After forming a polysilicon gate electrode 4, a resist film 11 is eliminated and thermal oxidation is performed for forming a thermal oxide film 13 on the gate electrode 4. With this thermal oxide film 13 as a mask, doping in high concentration with an N-type dopant (normally arsenic) is performed, the thermal oxide film 13 on the gate electrode 4 is eliminated, and doping in low concentration with an N-type dopant (phosphor) is performed for providing a low-concentration region 6. Thus, only the processes for thermal oxidation and elimination of the thermal oxide film 13 are added for forming an offset region without making the process to be complex, thus preventing the source/drain regions from being damaged.

Title: Microcomputer device
Inventor: NAKAGAWA SEIJI
IPC: G06F11/28
Filed: 1990-09-04
Abstract: PURPOSE:To eliminate a load when a system is made abnormal by providing a reset counter circuit to count reset signal outputs and a two input OR circuit. CONSTITUTION:A reset counter circuit 6 is provided to count the number of computer reset signals outputted by a counter circuit 2 and to output the signal of '0' or '1' according to whether the number exceeds a prescribed number or not. On the other hand, a two input OR circuit 5 is provided to input the output signal of the reset counter circuit and an oscillation signal from an oscillation circuit and to output an OR logic result to the counter circuit 2. Therefore, when the run-away of a program is generated, a reset signal generation circuit 3 loses the reset function of resetting a count value to the counter circuit 2 before turning to a set value, and the counter circuit is not reset but continues counting so that the count value can exceed the set value to generate the computer reset signal. Thus, since the microcomputer is eternally turned to a reset state when the program runs away, the abnormal-time load to parts constituting a system is eliminated.

Title: Reader for optical recording medium
Inventor: HORIE KIYOSHI
IPC: H04N5/84
Filed: 1988-09-20
Abstract: PURPOSE:To identify the erasing condition of a block and to increase the efficiency of the reading by dividing a belt-shaped data track into plural blocks and discriminating whether the counted value of a data reading signal from a block is higher or lower than a prescribed value. CONSTITUTION:At the time of the file writing of a card type optical recording body, a file is divided for a block 20, written, checked and when the writing error occurs, the data of the block 20 are erased. The erasing of the data is executed by writing to the belt shape over the range of the writing of a data bit 21. Thus, at the identifying circuit, the counting for four bits of the data bit 21 is executed at the block 2 where the correct writing is executed, and at the erased block, the counting is not executed and therefore, it can be identified by the difference in the counted value. Since the block with a writing error can be identified while the block is read, the writing and reading efficiency can be drastically improved.

Title: Device for vapor deposition of thin film
Inventor: YAMANISHI KENICHIROU
IPC: C23C14/22
Filed: 1983-12-12
Abstract: PURPOSE:To achieve vapor deposition of the high-quality thin film by preventing clogging of a nozzle and the increase in temperature of a substrate with an extremely less electric power by heating the periphery of the nozzle of a crucible locally by irradiation with a beam such as a laser beam. CONSTITUTION:A substrate 18 is held 22 and the air in a tank 1 is exhausted to about 10<-6>Torr. The substance to be deposited in a crucible 4 is heated 6 and a vapor pressure in the crucible is kept at about 0.1-10Torr. A laser beam 31 from an oscillator 30 irradiates a periphery of a nozzle 4a to keep high temperature locally. Accordingly, vaporized substance 5 does not become droplets and is jetted into a vacuum. A part of clusters become cluster ions 16 by thermions 13 by means 12 and are accelerated by an electric field between electrodes 14 and thermion attracting electrodes 10 to be vapor-deposited on the substrate 18. Neutral clusters 15 are also deposited on the substrate 18 by the kinetic energy of jetting from the crucible. By this constitution, liquefaction of the substance to be deposited can be prevented with less electric power and dispersion of heat upward of the crucible is also prevented. The increase in temperature of the substrate 18 can be prevented and adverse conditions at fabrication of thin films are eliminated.

Title: X-ray spectroscope
Inventor: ARAI TOMOYA
IPC: G21K1/06
Filed: 1989-09-13
Abstract: PURPOSE:To reduce absorption by an X-ray tube target itself and to increase an effective range of an apparatus by a construction wherein a spectroscopic crystal is disposed along a straight line passing an incident part of X-rays separated into its spectral components is made to oppose the target. CONSTITUTION:A guide track 8 of a spectroscopic crystal 7 is so provided as to be directed to the direction of an X-rays which enters an observing device 5 through a window 6 of incidence thereof. In other words, the crystal 7 can be moved along the track 8 and, at the same time, the incident angle theta of the X-rays can be set arbitrarily by rotating the crystal within the plane of paper. When the X-rays of relatively long wavelengthes are made to enter the device 5, accordingly, the X-rays emitted at a large takeout angle alpha from a target face of an X-ray tube is used, and when the X-rays of relatively short wavelengthes are made to enter, the X-rays of a small takeout angle is used. In other words, the takeout angle on the target face is increased as the absorption of the X-rays by the target becomes large, the absorption by the target itself is thereby reduced, and thus an effective wavelength range of the apparatus can be enlarged.
