IPC: H04N1/00
Filed: 1985-07-11
Abstract: PURPOSE:To correctly reproduce a frame picture by reading including an area between adjacent frame picture continuously and recording in the second recording medium when recording a set of succeeding frame pictures. CONSTITUTION:A reader control circuit 66 gives a reading start signal S to a picture processing part 67, starts the reading of a film by a CCD 39 and outputs the reading picture information to an optical disk device control circuit 70. The optical disk control circuit 70 sets a low order memory counter of the cartridge unit information of an index information memory in the control circuit 70 to '1' by a mark detecting signal M and records successively the picture information successively fed in an optical disk. At this time, a recording address K on the disk of a scanning line fed initially immediately after the input of the signal M is stored in the index information memory as the address information of the index information and as the first frame of the index information, 'N, I, K' is registered. Thereby, the frame is prevented from failing to read and a correct information reproduction can be executed.

Title: A/d converter
Inventor: YAMADA HARUYASU
IPC: H03M3/02
Filed: 1988-06-21
Abstract: PURPOSE:To realize A/D conversion with high accuracy even if the accuracy of the component is low by devising the A/D converter in such a way that an output of an integration device connecting to the output of the D/A converter is varied proportioning to the output of the D/A converter. CONSTITUTION:A comparator 2-2 gives a logic 0 when the input voltage is lower and a comparator 2-3 gives a logic 1 output when the analog input signal is smaller and its differential part is further smaller than a constant value, the inverse of K. The digital signal is retarded during one sample period by a register 3, the digital signal is given to a D/A converter 4 and the output of the D/A converter reduces slightly the output voltage of the integrator 2. When the differential output of an adder 1 is smaller further than the level of the inverse of K, the output voltage reduction in the integrator 2 is large. Thus, the output of the integrator 5 varies with the analog input signal and a digital output signal of the comparator 2-2 is obtained in following thereto. Thus, even with the accuracy of components in use, the A/D conversion with high speed and high accuracy is enabled.

Title: Acceleration tube
Inventor: SHIODA MASARU
IPC: H05H9/00
Filed: 1988-06-23
Abstract: PURPOSE:To obtain an acceleration tube of a good energy efficiency and a high electric field by using a substance of the boiling point of 0 deg.C or lower at the atmospheric pressure such as liquefied nitrogen as a refrigerant. CONSTITUTION:A refrigerant 4 of the boiling point of 0 deg.C or lower at the atmospheric pressure is passed through a refrigerant jacket 3 attached to an acceleration tube 1 of a normal conductive material. In the case of the main body 1 of the acceleration tube is copper and the refrigerant is liquefied nitrogen, the boiling point of nitrogen is 77 deg.K and the specific resistant rho1 of copper at the corresponding time is 0.2muOMEGA/cm<2>. The specific resistance rho2 of copper in the case the refrigerant is water is 1.72muOMEGA/cm<2>. In this way, the electric resistance of the acceleration tube body 1 with liquefied nitrogen decreases by the ratio K=rho1/rho2 and the ohmic loss becomes 1/K. As the electric field intensity of the acceleration tube is proportional to K<1/2>, the acceleration of charged particles becomes about K<1/2>. Thus, the energy efficiency is increased and high electric field acceleration is made possible.

IPC: H01L21/66
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To highly reliably evaluate the presence of heavy metal contamination over the whole surface of a silicon wafer and the lowering of life time, etc., by etching the silicon wafer with an aqueous solution of alkali and then observing the surface state of the silicon wafer. SOLUTION: A silicon wafer is immersed in an alkali aqueous solution to carry out alkali etching. After the alkali etching is terminated, the silicon wafer is cleaned and dried, as required, and the surface state of the silicon wafer is observed. If there is heavy metal contamination, etc., due to the alkali etching, clouding is generated on the wafer with high sensitivity, so that simple visual observation is performed under an illumination of a fluorescent lamp or a light converging lamp. In this case, the heavy metal contamination part is verified by visual observation under the illumination of the fluorescent lamp. Etch-pits, etc., due to slip dislocation, etc., are verified by visual observation under the illumination of the light converging lamp. Furthermore, detects such as OSEs, etc., are verified through microscope observation.  Thus, highly reliable, safe, simple, low cost, and quick evaluation can be performed for the entire surface of the wafer.

Title: Positioning device
Inventor: TAKANO TOSHIO
IPC: G05D3/12
Filed: 1986-06-30
Abstract: PURPOSE:To eliminate the unstableness of a servo system and to present the occurrence of noise by securing synchronism between the control of a positioning device done for fixed time and the detecting cycle of the absolute position of an absolute position detector. CONSTITUTION:The timing with which the present position of a movable stage 10 via an absolute position detector C is controlled accurately to a 2ms cycle by a real time clock RTC20. Thus the interruption signal S2 to be applied to an MPU1 is also set accurately at 2ms and the control timing with which the MPU1 calculates the following deviation and outputs the speed signal S1 is set accurately at 2ms. This control timing has a delay just by a constant time to the detection timing. Therefore the follow-up deviation is fixed when the interpolated control target value has its change at a fixed speed. Thus the speed of the stage 10 is also fixed and therefore the unstableness of a servo system is improved.

Patent JP-H0319340-A (JP)
Title: Manufacture of semiconductor device
Inventor: KUNII MASABUMI
IPC: H01L21/336
Filed: 1989-06-16
Abstract: PURPOSE:To make it possible to form a high-efficiency TFT at a high throughput using a low-temperature process by a method wherein in a method of forming an insulating film on the surface of a semiconductor by a chemical vapor growth method, the concentration of diluent gas, such as helium, neon, argon and xenon gases or the like, is changed to a film-forming time. CONSTITUTION:An SiO2 thin film 203 which is used as a gate insulating film is formed on a polycrystalline silicon thin film 202 made to perform a solid phase growth. In case a PCVD method is used for the film formation of the SiO2 thin film 203, inert gas, such as He gas or the like, is added to the mixed gas of SiH4 gas and N2O gas for reducing damage to the film 203. In the PCVD method, in case He gas is used as diluent gas in the gas flow rate ratio of low-temperature gas, the flow rate of the He gas is changed to a film-forming time. When the flow rate of the He gas is changed, the He gas is brought into a state that its amount of dilution is large in the vicinity of an Si/SiO2 interface, that is, though the damage to the film 203 is very small, the film formation progresses in a state that a film forming speed is slow and as the film formation becomes more distant from the Si/SiO2 interface, the film-forming speed becomes first. By adopting such a film-forming method, a good Si/SiO2 interface is realized as the film-forming time is kept short.
