Title: Disk attachment and detachment mechanism
Inventor: NAKADAI TSUTOMU
IPC: G11B17/032
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To allow only the moving speed of a disk supporting means during detachment of a disk to be slowed down by performing attachment and detachment of the disk while changing the moving speed of the disk supporting means at a predetermined position of a spindle. SOLUTION: A rack 6 is moved by allowing respective projections 4A (4B) on an eccentric plate 4 to be sequentially engaged with notches 6A (6B-6D) of the rack 6. With the rotation speed of the eccentric plate 4 at around 180 deg., by allowing a disk tray to be positioned at a relative position where a disk is about to be attached to a spindle adaptor, the moving speed of the disk tray can be reduced to the slowest level at the time when the disk is attached to, i.e., transferred to, the spindle adaptor from the disk tray. Thus, the disk can be slowly and surely attached to the spindle adaptor.

Title: Image sensor
Inventor: YAMAMOTO YASUNAGA
IPC: H04N5/335
Filed: 1987-05-07
Abstract: PURPOSE:To obtain a sensor high in resolution by a method wherein an optical information is directed through an optical waveguide provided on a sensor chip to a photoelectric converting element provided apart from the incident position and also the cut end. CONSTITUTION:A sensor comprises a scanning circuit 1, a photoelectric converting element 6 (2a-2i), an optical waveguide 5 (3a-3i), and pixels 4a-4i which are provided at the cut end face of a chip almost perpendicular to the surface of this paper. And, a reflective layer 8 and a dielectric layer 14 lower in a refractive index than the optical waveguide 5 are provided, an incident position 12 of the optical information represents the position of the read-in pixels, and the incident light passes through the optical waveguide with comparatively small attenuation and reaches the upper part of the photoelectric converting element 6. The reflective layer 8 serves so as to prevent the light rays reaching the terminal end of the optical waveguide 5 from passing upwardly through the optical waveguide 5 if the light rays are not satisfied with the total reflection condition when these are reflected by the surface of the element 6 or the terminal end of the optical waveguide, and direct the rays to the photoelectric converting element 6 as efficiently as possible. By these processes, a sensor high in resolution can be obtained.

Title: Evacuating type vapor growth device with gas dispersing mechanism
Inventor: YAMAZAKI KEN
IPC: C23C16/455
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To break the vacuum state in a reaction chamber in a short time without causing film peeling or diffusion of products or the like in the reaction chamber by dispersedly reducing the kinetic energy of an inert gas injected from an injector and introducing a large flow rate of the inert gas into the reaction chamber. SOLUTION: The gas discharging side of an injector 3 is set to the inside of a reaction chamber 5, and plural gas discharging ports 3a are opened at the tube walls thereof. The opening positions of the plural gas discharging ports 3a are made different so as to prevent their overlapping. Moreover, the aperture and shape of the gas discharging ports 3a in the injector 3 are changed, and the conductance is changed to control the amt. of the gas to be discharged from each gas discharging port 3a. Inert gas is introduced into the reaction chamber 5 as being branched from each gas discharging port 3a while it reaches from the base part of the injector 3 to the gas discharging side, and the kinetic energy of the gas is reduced. Thus, a large flow rate of gas can be introduced without causing peeling and whirling.

Abstract: PURPOSE:To contrive improvement in transfer efficiency by a method wherein the concavity of a potential well is removed in to such a manner that one side wall of a transfer channel is brought in contact with the threshold voltage controlling impurity region of a transfer gate over the overall length of the side wall. CONSTITUTION:The right side wall of a transfer channel 3 (transfer channel impurity introduction region 33) comes in contact with the impurity diffusion layer 32, to be used for element isolation, and also its left side wall comes in contact with a p-type impurity introduction region 40, to be used for control of transfer gate threshold voltage, irrespective of the state whether a transfer gate 26 is connected or not. Therefore, the effect (narrow-channel effect) which the transfer channel 3 receives from the impurity diffusion layer 32 does not vary between the part containing the transfer gate 26 and the part not containing it, and almost equal effect is inflicted on the entire length of the transfer channel 3. Accordingly, the transfer efficiency of the transfer channel 3 can be improved.

Title: Semiconductor integrated circuit
Inventor: YOSHIDA MASAKO
IPC: H01L27/088
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To speed up the circuit operation, without increasing the current consumption, by changing the threshold of a MOSFET such that this threshold is low, its gate is on, the threshold is high after a specified time const. elapsed, the gate is off, and the threshold returns to the original level after a specified time const. elapsed. SOLUTION: A laminate film having SiO2 films 4 on the upper and lower surfaces of a SiN film 5 beneath gate electrodes 1. In the case of an nMOS, the voltage applied to the gate electrode 1 is changed from L(low level) to H(high level) to flow a current between a source 2 and a drain 3 to trap electrons at an SiN film 5 interfaces between the oxide film 4 to raise the threshold enough according to the trapped amt. of the electrons after a specified time. While the gate is H, the threshold is kept high. When turning from H to L, the trapped electrons are discharged to return the threshold to original level. Since the threshold is different when turning on and off, the circuit operation can be performed at high speed.
