Title: Electron beam generator
Inventor: TAKEGAWA ICHIRO
IPC: H01J37/248
Filed: 1988-05-31
Abstract: PURPOSE:To recover a trouble of a pulse beam generating circuit from the outside of a tank in a short time by disconnecting or connecting a continuous beam generating circuit and the pulse beam generating circuit with a circuit opening terminal and a circuit closing terminal. CONSTITUTION:A circuit closing circuit 24b is invariably connected to a bushing 23, a continuous beam generating circuit or a pulse beam generating circuit 21 can be freely selected. When the pulse beam generating circuit 21 fails, a circuit opening terminal 24a is connected to the bushing 23, thus the failed pulse beam generating circuit 21 is disconnected from the continuous beam generating circuit, the state that only a continuous beam can be generated is recovered. Or a state circuit closing terminal 24c is connected to the bushing 23, thus a spare pulse beam generating circuit 22 is connected, the original state that both a continuous beam and a pulse beam can be generated is recovered. Even if the pulse beam generating circuit fails, a continuous beam or a pulse beam can be generated in a short time by the operation outside a tank.

Title: Two-layer gate type semiconductor device and manufacture thereof
Inventor: MAARI KOUICHI
IPC: H01L29/788
Filed: 1992-04-23
Abstract: PURPOSE:To prevent the escape of electrons from a floating gate of a nonselected call at the time of writing without reducing erasing characteristics by increasing in thickness an end of a gate oxide film at the side of a drain between the gate and a channel. CONSTITUTION:A gate oxide film 4 between a channel and a floating gate is formed to be thicker at an end 4a of a drain side than the other part in a two-layer gate type semiconductor device. Accordingly, since the end 4a of the drain side is thicker than the other part, an electric field intensity of an end of the film 4 at the side of the drain 2 when nonselected at the time of writing is weakened. Therefore, electrons scarcely escape from a floating gate 5. That is, escape of the electrons from the gate of nonselected cell at the time of writing can be prevented without reducing erasing characteristics.

Title: Reference voltage generation circuit
Inventor: FUJII FUMIAKI
IPC: G11C11/4099
Filed: 1978-10-27
Abstract: PURPOSE:To simplify the reference voltage production circuit by applying the timing pulse in opposite phase with the word selection signal to the capacitance of dummy cell producing reference voltage. CONSTITUTION:In reading out the memory cell MC', at the precharge period of the data lines N, N', the capacitance Cds of the dummy cell DC is not charged with the timing pulse phio in opposite phase with the word selection signal phiw', and the pulse phiD is changed to 0 level at the same time when the readout of the memory content of the cell MC' is started. Thus, the data line N is the reference voltage potential intermediate to the high and low level read out from the cell MC' by the capacitance Cds of the cell DC, and the content of the cell MC' is read out via the sense amplifier SA. In reading out the memory cell MC, the reference voltage is similarly produced from the dummy cell DC', and two signal lines are unnecessary for the cells DC, DC' in MIS transistor to simplify the constitution, resulting in decreasing the occupied area of the reference voltage generating dummy cell.

Abstract: PURPOSE:To reduce the manufacturing cost of a product by eliminating common steel in the vicinity of an end face by a specific thickness, and subsequently, sealing up tightly both end part clad materials having a formed air-gap part, directly or through a packing material. CONSTITUTION:In the end face of three-layer stainless clad steel which has placed stainless steel 6 as a cladding material on both sides by placing common steel 2 between, the common steel 2 is removed by thickness of <=1/2 of plate thickness in the thickness direction by an acid dissolving method or cutting, etc. Subsequently, a cavity part 4 which has been formed is filled with a filling material 8 such as a resin, etc., and sealed up tightly by joining stainless steel 6, 6 by soldering or welding. Or said part is sealed up tightly by joining directly the stainless steel 6, 6. By using this method, a process of curling work, etc. becomes unnecessary, and generation of red rust of the common steel 2 can be prevented. Accordingly, the manufacturing cost of a product is reduced.

IPC: H04N1/00
Filed: 1984-06-28
Abstract: PURPOSE:To reduce the recording output time as the result of communication by providing a character image pattern generating section generating a character pattern of high and low quality to the same character. CONSTITUTION:A character image pattern generating section 5 and a control section 6 selecting a pattern are provided in a facsimile equipment having plural kinds of resolutions to the sub-scanning direction. When a control section 6 receives the information of the resolution at recording from an operating section, the resolution, character information and a character image pattern size are outputted to an image pattern generating section 5. The generating section transmits an abbreviated image pattern to a coding/decoding section 3 only for a complicated image pattern by the standard resolution and outputs an image pattern not abbreviated in other cases and the pattern is recorded on a recording section 2. Thus, when it is desired to recognize the result of communication earlier, the time is reduced by designating the standard resolution to the operating section 7.

Title: Optical head
Inventor: KONO HARUHIKO
IPC: G11B7/09
Filed: 1989-05-25
Abstract: PURPOSE:To simplify structure for supporting a light source and a condensing means by displacing the respectice light source and condensing means only in one direction of a tracking direction and a focusing direction. CONSTITUTION:When a defocus signal is outputted from a detector 8, the signal is processed by a signal processing circuit 9 and focusing is executed by exciting the coil of a drive part for focusing and displacing a driving circuit 10 for focusing in an optical axial direction. When a tracking shift signal is outputted from the detector 8, this signal is processed by a signal processing circuit 12 and tracking is executed by exciting the coil of a driving part 15 for tracking and displacing a driving circuit 13 for tracking in a direction orthogonal to the optical axial direction. Thus, since a semiconductor laser 1 and an objective lens 4 are respectively displaced only in one direction of the tracking direction or focusing direction, the supporting structure and driving part for the semicon ductor laser 1 and objective lens 4 can be simplified.
