Title: Semiconductor device
Inventor: KOIKE RYOICHI
IPC: H01L21/822
Filed: 1988-03-25
Abstract: PURPOSE:To eliminate a change in avalanche breakdown voltage with time by forming a diffusion layer under a one-conductivity type diffusion layer, the former diffusion layer having higher concentration than an other-conductivity type substrate and having a concentration distribution peak located in the vicinity of a junction of both conductivity types. CONSTITUTION:A diode additionally includes a third diffusion region 4 which has an impurity concentration distribution peak located in the vicinity of a junction portion between a first conductivity type region 1 and a second conductivity type diffusion region 2 and which is formed on the inside of an active region not to make contact with an element isolation region 3. Hereby, avalanche breakdown is produced at a junction portion between the diffusion region 2 and the diffusion region 4. The avalanche breakdown is thereupon produced at the bottom of the diffusion layer 2 separated away from the element isolation film 3, so that electron-hole pairs produced upon the breakdown are prohibited from being caught by a trap of the element isolation SiO2 film.

Title: Heat accumulating device
Inventor: NAKAZAWA YUJI
IPC: F24F5/00
Filed: 1988-03-24
Abstract: PURPOSE:To perform high-efficient storage of a cold heat, by a method wherein raw water is allowed to flow through ice-making liquid, cooled to temperature lower than an ice temperature, to produce ice, produced ice is caused to effect reflux togetherwith circulating water to separate it from an ice-making part, and is stored in a tank for exclusive use. CONSTITUTION:Ice 3 is produced in a way that raw water 11b is iced while it is floated in a granular state in ice-making liquid 10 cooled to temperature lower than an ice temperature. Namely, water is not cooled by the boiling action of a refrigerant as in a conventional device, but the raw water 11b is directly cooled in a state in which the ice-making liquid 10 is functioned solely as a heat conduction medium. Thus, there is no need to form not only a heat accumulating tank 4 but also an ice-making tank 2 as a pressure container. Ice 3 produced in the ice-making tank 2 is fed to the heat accumulating tank 4 togetherwith water 11a effecting reflux from the ice-making tank 2 to the heat accumulating tank 4 and can be forcibly separated away from the ice- making tank 2. Thereby, the ice 3 can be high-efficiently stored by the heat accumulating tank 4 for exclusive use.

Title: Transfer mechanism for movie film
Inventor: ROJIYAA UEIKUFUIIRUDO FUENTON
IPC: G03B31/02
Filed: 1988-03-25
Abstract: PURPOSE: To obtain a sound signal in synchronism with a video signal by allowing a sound gate to treat films having at least two different size standards, allowing these films to pass a common film passing route and relating the sound signal to one of the film size standards by a delay means.  
     CONSTITUTION: Sound cells SC 1 , SC 2  are combined in two different size standards and arranged close to each other in a sound drum, but even when the films are passed through the same film passing route, distances from a picture gate are slightly different between both the films. Although a sound signal is sent to a sound signal processing circuit ASP through a preampliifer PA and a switch SW1, only one sound cell generates an output in each time, the switch SW1 is set up based upon the size standard of the used film, necessary delay is applied to the sound signal by a sound delay circuit AD, and the delayed sound signal is outputted in synchronism with its related video signal. When a film passing distance between the picture gate and the sound gate is selected as above, delay related to one film size standard can be made zero. Consequently suitable synchronism between a picture and a sound can be obtained.

Title: Production of cast iron gear
Inventor: FUJIWARA YASUYUKI
IPC: C21D9/32
Filed: 1995-03-29
Abstract: PURPOSE: To produce a cast iron gear at a low cost with high accuracy and without the degradation in strength, quenching crack and rolling crack by exposure of the graphite grains of cast iron and consequently with high strength and good productivity. CONSTITUTION: A heating stage for heating a blank 1 consisting of the cast iron to a temp. at which the gear forming part 10 of this blank attains at least an austenitization region and a hot rolling stage for generating tooth parts by strongly pressing the projecting tooth profile parts 64a, 65a of a rolling die to the tooth forming part 10 of the blank 1 of the hot state existing in the austenitization region during the cooling process of the heated blank 1 are successively executed. Since the tooth parts are generated by utilizing the hot rolling which is low in thermal deformation resistance, the rolling crack is prevented and there is substantially no exposure of the graphite grains on the tooth faces. Since the old γ grains are made finer by the hot rolling, higher tenacity is obtd. and the quenching crack sensitivity is lowered.  Working strains remain less in the hot rolling and, therefore, the degradation in the accuracy is lessened by releasing of the residual stresses at the time of reheating.

Abstract: PURPOSE:To improve the resolution of a standard-color cathode-ray tube by improving the balance of currents stimulating luminous picture elements by preparing a face panel from a glass containing neodymium, which has the property of absorbing light with specified wavelengths selectively. CONSTITUTION:Curve (A) represents the light transmission characteristic of a glass containing neodymium, and shows stronger absorption in the wavelength range of 570-600nm compared to the light transmission characteristic of a conventional face-panel glass represented by curve (B). Therefore, the use of the glass containing neodymium makes only the emission peaks in the wavelength range of 570-600nm of the emission spectrum of a Y2O3: Eu phosphor or a Y2O2S: Eu phosphor to be absorbed. In addition, since at least one of the widely used Y2O3: Eu phosphor and Y2O2S: Eu phosphor can be used, the brightness is improved by about 30% in comparison with a conventional standard-color cathode-ray tue even after taking into consideration the about 20% decrease of the transmittance caused by the glass containing neodymium.

Abstract: PURPOSE:To prevent the rolling of a reproduced picture at the time of slow action and to prevent the occurrence of color dislocation in the reproduced picture by making the phase difference in a phase error output into '0' in a next cycle when the speed control output of a cylinder motor at the time of operating slowly is corrected. CONSTITUTION:The title device is equipped with a speed control means 8 to control the rotating speed of a cylinder motor 3 so that the rotating speed can be constant, a phase setting means to set the phase of the reference phase signal of a reference phase signal generating means 9 to the phase of the rotational phase signal of the cylinder motor 3, etc. When the speed control output of the cylinder motor 3 at the time of the slow action is corrected, it is made difficult to receive the influence of phase control by making the output of a phase control means 10 into the one in which the phase error is 0 and changing the phase of the reference phase signal so that the phase difference between the rotational phase of the cylinder motor 3 and its reference phase can be a previously set phase difference. Thus, the rolling of the reproduced picture at the time of operating slowly can be corrected without the occurrence of the color dislocation in the reproduced picture.
