Abstract: PURPOSE:To reduce grain diameter growth of a polycrystalline silicon crystal used for a gate electrode and to prevent polycrystalline silicon punch-through of injected ion during ion implantation. CONSTITUTION:Ion 6 such as oxygen is injected to a polycrystalline silicon film 5a which becomes a gate electrode for preventing grain diameter growth thereof when an MOS transistor is manufactured. Thereafter, ions 8, 10 are injected for forming source/drain regions 9 or 11 using the polycrystalline silicon film 5a as a mask. Thereby, it is possible to prevent grain diameter growth of polycrystalline silicon during heat treatment and to prevent punch-through of a gate caused by ion implantation during source drain formation.

Title: Liquid crystal display element
Inventor: ONO KOICHI
IPC: G02F1/1339
Filed: 1994-02-10
Abstract: PURPOSE:To prevent a liquid crystal material to be used in places of a low temp. from shrinking and deteriorating display characteristics by arranging spacers only in the spacing of a display region without arranging these spacers in the spacing of a non-display region, then continuously encapsulating the liquid crystal material into both spacings. CONSTITUTION:This liquid crystal display device is segmented to the display region A and the non-display region B by a partition wall 11. The spacers 3 are interposed in the display region A and the spacers 3 are not disposed in the non-display region B. The spacing between two sheets of the transparent substrates 1a, 1b of the display region A is, therefore, maintained always at the specified spacing. This spacing does not change and the specified spacing is obtd. even if the climatic temp. is low and the volume of the liquid crystal material shrinks. On the other hand, the liquid crystal material of the non- display region B is replenished through communicating holes 12 by as much as the shrunk component of the liquid crystal material. The generation of air bubbles between the liquid crystal phase 2 of the display region A and the transparent substrate 1b is obviated and the degradation of the display quality is prevented.

Filed: 1989-01-26
Abstract: PURPOSE:To quantitatively decide the state of mistakes in chucking by detecting the quantity of the change of a focusing error signal or a displacement signal and deciding that an optical disk is placed at a tilt when the detected value exceeds a specified value. CONSTITUTION:A CPU 22 turns a turntable 1 at about 360 deg. at low speed with the aid of a control signal SP. When the optical disk 4 is chucked obliquely to the turntable 1 in such a case, the focusing error signal FE varies with fine vibration just like large waviness, and a signal FS1 obtained by removing high frequency component from the signal FE by an LPF 16 varies just like large waviness between a maximum value and a minimum signal. The CPU 22 incorporates the maximum value of the signal FS1 held in a maximum value hold circuit 18 and the minimum value of the signal FS1 held in a minimum value hold circuit 19 and obtains the quantity of the change of the signal. When the quantity of change is larger than the previously set value, it is decided that the optical disk 4 is in the obliquely chucked state.

Title: Dressing of grindstone consisting of superhard abrasive grain
Inventor: IMAI TOMOYASU
IPC: B24B53/00
Filed: 1986-01-29
Abstract: PURPOSE:To permit the speedy reduction of the grinding resistance immediately after trueing by activating the breakage of abrasive grains by increasing the damage applied onto an abrasive wheel by grinding-working a dressing roll in the state where the peripheral speed is reduced below that in the normal grinding, immediately after the trueing of the abrasive wheel. CONSTITUTION:After the truing for an abrasive wheel 12 is completed, the revolution speed of a motor 13 for driving a grindstone is reduced by controlling a motor speed control circuit 40, and the peripheral speed of the abrasive wheel 12 is reduced below the normal speed. Then the cutting-in grinding work is carried out for a dressing roll at a constant speed. If the detection value of a grinding resistance detector 35 is larger than a standard value at this time, the grinding work for the dressing roll is continued, and if the detection value is less than the standard value, the grinding work is completed. Thus, the grinding work is carried out by reducing the peripheral speed of the abrasive wheel, and the damage of the grindstone 12 is increased by increasing the load per piece of the superhard abrasive grain, and the breakage of the abrasive grains is activated, and the formation of acute cutting edge is accelerated. Therefore, the rate of the reduction of the grinding resistance is increased, and the speedy restoration to the ordinary grinding resistance is permitted.

Title: Radioactive concentration measuring device
Inventor: SUZUKI YASUO
IPC: G01T1/167
Filed: 1992-02-03
Abstract: PURPOSE:To improve measuring accuracy by supplying sweep gas to lead enriched sample gas into a detector, thereby enabling positive measurement even in the case of the concentration of the sample gas being low. CONSTITUTION:Sample gas from radioactive material handling facilities flows into a dehumidifying tower 11A from a sample gas inlet through a valve 10A, and the ordinary temperature tower 11A removes moisture. An adsorption tower 13A adsorbs object gas from the sample gas dried at the tower 11A. In this case, the adsorption tower 13A is cooled by a temperature regulator 14A to increase the adsorption of the object gas. The passage time can be thereby enlarged to increase an enrichment ratio. After adsorbing the object gas for the fixed time, the valve 10A is closed and a valve 15A is opened, and the adsorption tower 13A is heated by the regulator 14A for the desorption of the adsorbed object gas. Sweep gas is then let flow from the valve 15A to lead the enriched sample gas into a radiation detector 17 through a valve 16A. A measuring appratus 18 then measures the radiation concentration from a detected (17) output signal.

Title: Scintillation detector
Inventor: OKAMURA MICHIO
IPC: G01T1/208
Filed: 1982-02-09
Abstract: PURPOSE:To make the titled detector cnduct a wide range of measurement by using a switch which is turned ON in accordance with the time of incidence of a radiation, by cutting most of unnecessary dark current inputted from a photomultiplier tube to a microammeter, and by improving thereby the lower limit of measurement given by the dark current. CONSTITUTION:When receiving an H-level signal as an input, a monomultivibrator 92 delivers a pulse signal 11 from its rise over to a time tp. It is needless to say that the pulse width of the pulse signal 11 is enlarged correspondingly when a radiation reaches in close vicinity in time to another and the monomultivibrator 92 is triggered again within the time tp. When the pulse signal 11 reaches, a switch 7 is turned ON only for a time equivalent to the pulse width of the signal and supplies a current 4' in this time to a microammeter 5. The microammeter 5 integrates a current value and calculates a radiation dose.
