Title: Etching device
Inventor: IWASHITA KATSUHIRO
IPC: C23F4/00
Filed: 1986-05-30
Abstract: PURPOSE:To surely reduce an auto-bias voltage by surrounding a substrate electrode arranged in a vacuum chamber and loaded with a substrate, a counter electrode opposed to the substrate electrode, and the space between both electrodes by a cylindrical body to confine plasma between both electrodes. CONSTITUTION:The substrate electrode 7 and the counter electrode 8 are provided in a cover 10 communicating with the inside of a vacuum vessel 1, and an insulator is interposed between the bottom face of the electrode 7 and the cover 10. A cylindrical body 11 formed with an insulator such as quartz is furnished in the cover 10, and the electrodes 6 and 17 and the space 15 between both electrodes are surrounded by the cylinder. The inside of the vessel 1 is firstly evacuated, then an etching gas is introduced into the electrode 6 and injected into the space 15 to keep the space 15 in a specified pressure atmosphere. A high-frequency power is impressed on the electrode 7 by a high-frequency power source 12 to generate plasma in the space 15, and the substrate is etched. At this time, the diffusion of plasma into the vessel 1 is prevented by the cylindrical body 11, hence the plasma density is increased, and the auto- bias voltage on the substrate 8 can be reduced.

Filed: 1990-05-16
Abstract: PURPOSE:To keep the ratio of water and rice to the optimum level and to improve the rice-cooking accuracy with a compact apparatus by putting a rice-cooking part and a dry rice-polishing part in the same main body and providing a weight-measuring part, a computing element and a controller. CONSTITUTION:For example, a rice-polishing part 3 and a rice-cooking part 7 are placed in a main body 1. A necessary amount of water 17 is roughly measured and poured into the cooking pot 70 while inspecting the scale 71 and the number 72 of the pot. The amount of water measured by a weight- measuring apparatus 72 is transmitted to a computing element to calculate the optimum amount of rice. At the same time, the rice polisher is driven and the rice polished in dry state is charged into the rice-cooking pot while measuring the weight of the rice with a weight-measuring apparatus 73. When the charged amount coincides with the value calculated by the computing element, a controller 80 stops the motion of the rice-polishing part 3 and closes an opening 10. A rice-cooking heater 74 is electrified to start the cooking of rice. The heating temperature of the rice is controlled at a prescribed level with a temperature detector 75 and the controller 80 to enable the cooking of rice in high accuracy.

Title: Film forming device
Inventor: HIURA YUKO
IPC: H01L21/205
Filed: 1989-05-19
Abstract: PURPOSE:To evaporate and dissipate a thin film and prevent the window from blurring by irradiating light having wavelength where the absorption coefficient for the window material is sufficiently small and the coefficient for the thin film is sufficiently large, to the irradiated light transmitting part of the window surface with a specific strength. CONSTITUTION:The emitted light of an ArF laser 1 is split with a beam splitter 2, and the transmitted light having passed through an attenuator 4 and a synthetic quartz window 5 irradiates the board 7 in a CVD(Chemical Vapor Deposition) chamber 6 with an intensity of 1MW/cm<2> or less, for example. And, amorphous silicon 8 accumulates on the irradiated part by photochemically decomposing disilane guided into the CVD chamber 6 by the beam of the ArF laser 1. While, the reflected light is further reflected by a total reflection mirror 3 and irradiates the transmitted light irradiating position of the synthetic quartz window 5 with an intensity of 10MW/cm<2> or more. When amorphous silicon 8a accumulated on the synthetic quartz window 5 becomes to have a specified thickness, it absorbs the reflected light by the beam splitter 2 of the ArF laser 1. This makes it evaporate and dissipate by temperature rise reaching the sublimating or boiling point or higher, and prevents the window from blurring.

Title: Semiconductor laser
Inventor: IKUWA YOSHITO
IPC: H01S5/00
Filed: 1988-05-19
Abstract: PURPOSE:To lower operation current and perform mode control easily to obtain high light output by providing a pair of ferromagnetic bodies which give opposite magnetic fields in the length direction of an oscillator at both sides of an active area. CONSTITUTION:Magnetic field is applied in -z direction at the right side of an active area 13 and in +z direction at the left side of the active area 13. In this kind of magnetic field, positive holes and electrons flowing toward the right side of the active area 13 receive a force in the left (-y) direction from the magnetic field toward -z direction so that diffusion in horizontal direction is controlled. Similarly, positive holes and electrons spreading toward the left side of the active area 13 receive a force in right direction by a magnetic field toward +z direction and diffusion in horizontal direction is controlled. Thus, current which does not contribute to laser oscillation is controlled and the threshold current and operation current can be minimized. It allows a basic mode to be maintained even if the width of active area is enlarged for increasing output.

Title: Frame synchronizing circuit
Inventor: FURUBAYASHI MASAO
IPC: H04L7/08
Filed: 1980-09-08
Abstract: PURPOSE:To prevent the missynchronization distortion and to keep the phase of main frame timing, by inhibiting the phase set of the main frame timing, when an auxiliary frame synchronizing circuit is not synchronized to a received data. CONSTITUTION:A received data 1 and an auxiliary frame pattern from an auxiliary fram pattern generator 23 are compared with each other and synchronism is made with a count output of a coincidence pulse and dissidence pulse. When the auxiliary frame shows asynchronism at the count output, the advancement of the auxiliary frame pattern is stopped until the auxiliary fram pattern coincides with the received data to move the auxiliary frame pattern into a drawing operation, and the phase set of a main frame timing generator 27 is inhibited with the auxiliary frame timing signal during the auxiliary frame synchronism to keep the phase. Thus, the missynchronizing distortion can be prevented and the synchronizing restoring time can be shortened even if the synchronizing distortion is produced.

Abstract: PURPOSE:To enable a ribbon feed quantity to be switched simply and easily, by providing an intermediate gear between a take-up driving shaft and a toothed roller, and switching the feed quantity of an ink ribbon through changing the reduction gear ratio. CONSTITUTION:When an intermediate gear 36 is fitted into a first shaft support hole 40A with a boss 38 on the upper side, rotation of a take-up driving shaft 31 is transmitted to a toothed roller 27 through a large diameter gear 33 and the intermediate gear 36. When the intermediate gear 36 is fitted into a second shaft hole 40B with the boss 38 on the lower side, it is engaged with a small diameter gear 34 in a two-stage gear part 35 through a height adjustment, so that the rotation of the shaft 31 is transmitted to the toothed roller 27 through the small diameter roller 34 and the intermediate gear 36. By changing a shaft support position for the intermediate gear 36 in this manner, the reduction gear ratio in transmission of the rotation from the take-up driving shaft 31 to the toothed roller 27 can be changed.
