Filed: 1979-12-14
Abstract: PURPOSE:To compensate a temperature extending over a very wide range, by changing the effective electrode area of a piezoelectric oscillator by a duty pulse to be varied. CONSTITUTION:The oxcillation frequency of a ring oscillator RG consisting of odd number of C-MOS invertors is linearly varied by a temperature. This output and the output of the frequency dividing circuit D are provided to the mixer MR, and when the difference of both the frequencies is converted to a digital data by the data converting circuit DT and it is provided to the counter CT, a pulse of duty corresponding to an output data of the converting circuit DT is generated from the counter CT.

Title: Self-refresh period adjusting circuit for semiconductor memory
Inventor: KURUMA KIGEN
IPC: G11C11/406
Filed: 1994-07-14
Abstract: PURPOSE: To obtain a self refreshing period control circuit of a semiconductor memory device capable of actively optimizing the refreshing period in accordance with the variation of a power source voltage and peripheral temperature and also reducing the consumption of an electric current. CONSTITUTION: This circuit is provided with a temperature detecting part 40 detecting the variation of the peripheral temperature to a pre-set detecting temperature and a voltage detecting part 42 detecting the variation of the power source voltage to a pre-set detecting voltage. Either of a dividing pulse string outputted from a frequency divider 38 or either of many combined pulse strings generated by logically combining a dividing pulse string is selected with a pulse selecting part 44 in accordance with detected signals from both detecting part, whereby a master clock signal ϕRd is generated. Therefore, a reference value or above and below of the peripheral temperature/the power source voltage are sensed, the refreshing period is actively varied, and then the optimal period is obtained.  Also, since the optimal period near the longest data holding time of a memory cell is more precisely selected, unnecessary refreshing operation is restrained and the consumption of the electric current is reduced.

Title: Electronic still camera
Inventor: KUBO HIROAKI
IPC: H04N9/07
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To make it easily to observe a preview image outputted onto a monitor, to more quickly process image data and to output them on the monitor by varying at least one of exposure setting, pixel interpolating means and gradation characteristics to be used for an exposure control part, pixel interrelation part and gamma correction part at the time of preview image photographing and recording image photographing. SOLUTION: After the diaphragm operating of a CCD 8 at the time of preview image photographing is set larger than for recording image photographing, the shutter speed at the time of preview image photographing is set lower than at for recording image photographing so as to attain over exposure while keeping the diaphragm the constant. Thus, a more natural image in the case of outputting a preview image on the built-in monitor is enabled and focusing is facilitated. At the time of interpolating processing to the preview image, preview image data are more quickly processed at a pixel interpolation part 13, while using an interpolating means at high processing speed and through a monitor 20, a user can immediately confirm the image.

Title: Fault diagnosis method of picture processor
Inventor: OOHAYASHI ISAO
IPC: G16H10/60
Filed: 1979-12-14
Abstract: PURPOSE: To realize a diagnosis for the fault or the like in a simple way, by detecting the standard detection subject to obtain the difference between the original data obtained newly and the standard original data and then displaying directly the data on the difference of the original data in the form of the gradation information.  
     CONSTITUTION: For a diagnosis via CT (computer tomogram) device, the phantom as the prescribed standard detection subject is set at the fixed position of the scanner main body 2. Then the data equivalent to a scanning are converged to be stored in the original data holding area CE of the auxiliary memory 4 in the form of the unprocessed raw data. The raw data are collected under the same conditions as the original data collecting moment in an appropriate period right after the working of the CT device starts to be recorded at the holding area NE of the memory 4. Here the difference is obtained between the two corresponding data to be displayed on the display unit 5 as a gradation picture. At the same time, a statistic process is carried out for the obtained picture to deliver a numerical output. Thus a quantitative decision is possible for the aging or the like. In such way, the fault of the device can be detected without adding any new device to the conventional CT device.

Title: Etching method for quartz substrate
Inventor: SHIROTA TOSHIMITSU
IPC: H01L21/3065
Filed: 1980-11-21
Abstract: PURPOSE: To provide selectivity and to enable the multiple working of a quartz substrate by specifying a resist material and a reactive gas in a reactive dry etching method for the substrate.  
     CONSTITUTION: When a quartz substrate is etched by a reactive ion beam etching method or a reactive RF sputter etching method, a thin Ti film is used as a resist material, and CF 4  as a principal component is mixed with CCl 4 , CBr 4  or CI 4  as a gaseous additive and used as a reactive gas. The Ti film has superior selectivity to the quartz substrate and is applicable to all of said methods. The etching speed ratio of the quartz substrate to the Ti film, that is, the selection ratio is enhanced by adding such carbon halide to gaseous CF 4 . The reason is unknown, yet it is considered that the added gas is decomposed more easily on the surface of the Ti film in plasma than CF 4  and protects the interior.

Filed: 1982-09-20
Abstract: PURPOSE:To maintain cleanly an optical transmission part without providing any pressure regulator in a working machine which scans the laser light irradiation nozzle in a head part by carrying the head part in the intermediate part of a bellows body of which both ends are fixed to the stationary duct in the optical transmission part and a fixing part. CONSTITUTION:Bellows bodies 50, 52 of which the ends are fixed in the laser light 100 outlet of a duct 32 and a fixing part 54 maintain an optical transmission part 38 in a hermetic state together with a head part 12 and ducts 30, 32. Clean gas is packed in such hermetic chamber. The laser light 100 is conducted to an irradiation nozzle 14, and the head part 12 is driven in an arrow direction by a driving mechanism 16, by which the work 10 is worked. The juncture of the bellows bodies 50, 52 permits the transfer of the gas between both of them. Therefore if it is assumed that the part 12 is moved, for example, to the left, the volume in a bellows chamber 51 decreases and the pressure in the chamber 56 tries to increase but since the gas moves from the chamber 56 into the bellows chamber 58, the gaseous pressure in the hermetic chamber is maintained constant.

Abstract: PURPOSE:To restrain a magnetostrictive vibration noise without using any permanent magnet or yoke by air-tightly sealing members having a relative permeability of 1 at a room temperature in end plates on the stationary and movable sides of an insulative cylinder with brazing metals including silver having a high melting point. CONSTITUTION:Sealing fittings 2a-2d made of non-magnetic metal of high nickel- chrome steel are air-tightly sealed in an end plate 4a on a stationary side and an end plate 4b on a movable side with brazing metals 3a-3d including silver having a melting point of 600 deg.C or more. Accordingly, all component parts of a vacuum container are made of non-magnetic substances having a relative permeability of muSapprox.=1. The other component parts are non-magnetic, that is, no ferromagnetic substance is used for the component parts of a vacuum breaker. The sealing fittings 2a-2d are made of non-magnetic substances having a relative permeability of muSapprox.=1 so that a density of a flux passing through the fittings 2a-2d is the same as that in the vacuum or atmosphere in the vicinity of the fittings. Therefore, any magnetostrictive vibration cannot be generated in the fitting 2a-2d.
