Title: Connection structure of vacuum chamber in particle accelerator
Inventor: BIZEN TERUHIKO
IPC: H05H7/14
Filed: 1992-08-14
Abstract: PURPOSE:To prevent increase in the impedance at a connected part by preventing difference in steps that causes abrupt change in the cross section in the inner circumferential surface of the connected part. CONSTITUTION:A groove part 5 and a protruded part 6 that are fitted in with one another, are formed on the connected end part of vacuum chambers 1A and 1B that are to be connected together, and the groove part and the protruded part are fitted together, to connect the both vacuum chambers together. A taper surface 8, the inner diameter of which is gradually widened to the connected end side, and an expanded diameter surface 9 continuing to the taper surface 8, are formed on the inner circumferential surface of the connected end part of the both vacuum chambers. It is thus prevented that the both vacuum chambers are erroneously fitted together in a displaced state, due to the fitting between the groove part and the protruded part. The size error of the vacuum chamber is eliminated by forming the taper surface and the expanded diameter surface.

Title: Method and equipment for removing radioactive iodine
Inventor: FUKAZAWA TETSUO
IPC: G21F9/02
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To dispense with off-gas treatment equipment of a factory for manufacturing fuel for transmutation and to enable removal of radioactive iodine in a form suitable for a material of the fuel for transmutation by a method wherein the radioactive iodine is made to react with silver and removed from gas or a solution and then made into a compound with a metal element having a valence number of trivalence or above. SOLUTION: Radioactive I of a long half-life in spent atomic fuel is once dissolved in a nitric acid solution in a reprocessing dissolution process and then transfers into a vapor phase. The radioactive I existing in the fuel in the form of a solid cesium iodine CsI or the like transfers into a liquid phase in the form of a negative ion I-at the time of dissolution in a nitric acid and it is oxidized by the nitric acid or the like and transfers into the vapor phase in the form of I2. The I in the vapor phase is made to be absorbed by an alkali scrubber or adsorbed by a silver-series adsorbing material and removed. The I is removed by making it react with a metal element of at least trivalence being suitable for transmutation.  By providing equipment for making it react with cerium Ce, for instance, the I in off-gas from the dissolution process reacts with the Ce and becomes CeI3 and can be separated from other components and removed.

Title: Manufacture of semiconductor device
Inventor: FUJIMURA SHUZO
IPC: H01L21/31
Filed: 1985-09-30
Abstract: PURPOSE:To improve an oxidizing rate and to prevent a plasma oxidizing unit from deteriorating or the consumption of power to no avail by supplying power of a power source in a DC manner to a magnetron. CONSTITUTION:If power supplies from a magnetron power source 1 to a magnetron 2 is the same, the oxidizing rate increases as the duty is larger, and when DC is supplied, the maximum oxidizing rate is obtained. Since the oxidizing rate can be raised if the power supply to the magnetron is in a DC manner, it can prevent a plasma oxidizing unit from deteriorating due to the increase in the improper peak current like in the conventional one, an arc discharge from occurring and the consumption of power to no avail from occurring.

IPC: G10L25/00
Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To easily confirm and grasp the existence of sound data which has been copied illegally by embedding one of bit data of security data into plural Fourier transform coefficient units respectively. SOLUTION: A blocked Fourier transform coefficient generating means 5 executes Fourier transform of blocked sound data in each block and calculates a Fourier transform coefficient.

Title: Image recorder
Inventor: SHIBAKITA SHUNEI
IPC: B41J2/345
Filed: 1989-08-25
Abstract: PURPOSE:To record an image with arbitrary two types of linear densities using one thermal head by a method wherein two trains of heating elements of different gaps are adjacently disposed on one substrate of a thermal head, and a sheet of thermal recording paper is pressed down against each of the two trains by a platen roller. CONSTITUTION:On a heat resistant layer 106 of a thermal head 1, a train of heating resistors 1021a with a gap corresponding to 300 dpi and a train of heating resistors 1021b with a gap corresponding to 400 dpi are adjacently arranged. Recording paper 2 is pressed down against each of the heating resistors 1021a and 1021b by a platen roller 3. The heating resistors 1021a and 1021b are electrically conducted in a selective manner. In this manner, using the single thermal head 1, an image recording can be carried out with two types of linear densities 300 dip and 400 dip. Because the heating resistors 1021a and 1021b are allowed to be formed with a gap of a recording linear density, the production of a thermal head is facilitated. In addition, the heating resistors 1021a and 1021b are formed with a gap corresponding to 300 dpi and 400 dpi in this invention, but it is needless to say that each of them can be formed with an arbitrary gap.

Title: Semiconductor storage device
Inventor: TANAKA ISAO
IPC: G11C11/41
Filed: 1992-08-17
Abstract: PURPOSE:To prevent malfunction due to a noise on a bit line and to increase a speed for reading data. CONSTITUTION:Before starting reading operation, a bit line BL is pre-charged so that the margin of the relation of upper or lower level of the potential of the bit line BL to the circuit threshold of a sense amplifier 117 becomes large enough by means of a potential controlling means 100. Reading data from a memory cell 111 on the bit line BL is started by means of a signal on a word line WL controlling the output of the data. By synchronizing with the reading, the potential of the bit line BL is adjusted so that the margin of the relation of upper or lower level of the potential of the bit line BL to the circuit threshold of the sense amplifier 117 becomes minimum by means of the potential controlling means 100. Consequently, the output of erroneous data caused by the noise on the bit line BL at the starting time of reading is prevented and the speed for reading data is increased at the same time.
