Title: Magnetic picture recording and reproducing device
Inventor: HASEGAWA KENICHI
IPC: H04N9/82
Filed: 1980-05-23
Abstract: PURPOSE:To ensure the high-speed elimination of jitter, by produding through a PLL a continuous signal synchronized in phase with a synchronous signal extracted out of a composite video signal to be reproduced and increasing the sensitivity of a phase comparator included in the PLL only when a head is switched. CONSTITUTION:A switch SW1 is made to conduct for a certain period of a corresponding synchronous signal by a horizontal synchronous signal which is as an output of a synchronous signal separating circuit 32. A constant current source I1 is connected to the common emitter of transistors (TR)Q1 and Q2 of a differential switching circuit. The n-division output given from a dividing circuit 36 turns on either TRQ1 or Q2. The current flows into or out of a low pass filter 38 through a phase comparator 35. Thus a variable frequency scillating circuit 37 is controlled, and a multivibrator 101 triggered by a jitter detection output changeovers a switch SW2. As a result, the detecting capacity of phase difference of a comparator 35 is increased to ensure a high-speed elimination of jitter.

Title: Precision shearing method
Inventor: HIRAYAMA TOKUYA
IPC: B21D28/16
Filed: 1979-06-06
Abstract: PURPOSE: To improve the surface properties and dimensional precision of blanked section, by laying a similar or soft material beneath the metal to be blanked, blanking them simultaneously.  
     CONSTITUTION: An auxiliary material 4 of soft or similar property as the material being blanked 3 is laminated at least one layer between the material being blanked 3 and a die 2, and the two materials are blanked simultaneously. At this time, the upper surface of the material being blanked 3 receives a blanking force from a punch 1, while the lower surface receives a reaction force from the auxiliary materail 4. Therefore, since the material 3 is compressed in the thicknesswise direction and the deformation strain is released in the circumferential direction, hydrostatic pressure acts in the vicinity of the punch biting area. That is, the tensile force acting on the material being blanked 3 is reduced until lower than the stress value enough to cause repture, so that occurrence of crack may be restrained. On the other hand, the blanking state becomes equivalent to that of the thickness combining the material being blanked 3 and the auxiliary material 4, and the ratio of clearance to the plate thickness becomes relatively smaller, so that precision shearing may be done easily.

Title: Paper sheet feeder
Inventor: KIKUCHI YUTAKA
IPC: G03B27/00
Filed: 1979-06-05
Abstract: PURPOSE: To conveniently improve the paper sheet feeding function of a sheet feeder and eliminate the erroneous operation thereof and double feeding of the sheets in an electronic copying machine or the like by laying an underlay having suitable weight corresponding to the copy sheet between the copy sheet and the bottom plate when feeding the sheet having various thickness and specific weight.  
     CONSTITUTION: An article having smaller weight per thickness thereof than a specified sheet such as, for example, an underlay 6 made of foamed styrol or the like is laid between a copy sheet 4' such as, for example, the second original having larger weight per thickness thereof than the specified sheet and the bottom plate 1. This means that a curve A 0 -E is a gradient of the weight per thickness of the underlay. By utilizing the underlay 6 it is improved to a curve A 0 -E-C from a curve A 0 -C 0  if the underlay 6 is not used. That is, the contact pressure between the feed sheet roll and the sheet can be set within allowable suitable range. According to this configuration, the sheet feeding performance can be simply improved to eliminate the missing of the fed sheet and the feeding of double sheets.

Title: Refrigerating plant
Inventor: TAKEMASA KAZUO
IPC: F25B7/00
Filed: 1988-03-24
Abstract: PURPOSE:To secure a minimum level of cooling effect by the evaporator by avoiding the suspension of the cooling action by supplying the evaporator, through separate decompressors, with a cooling medium having a low boiling point which was separated and condensed by a cooling medium leaving the evaporator and a cooling medium having a high boiling point which was condensed and separated. CONSTITUTION:When a cooling medium having a low boiling point is used, clogging tends to occur in the first capillary tube 9 which is smaller in diameter because of the freezing of moisture mixed in the cooling medium as it was cooled down to a substantially low temperature in the heat exchanger 8. While clogged, the cooling medium cannot be supplied to the evaporator 11 from the first capillary tube 9. If the liquid cooling medium from the gas/liquid separator 5 is supplied directly to the heat exchanger 8 through the second capillary tube 10 as conventionally conducted, the cooling medium cannot be supplied to the evaporator 11 at the time of the clogging of the first capillary tube 9. But, as the cooling medium having a high boiling point is supplied from the second capillary tube 10 to the evaporator 11, at least the cooling effect by the evaporation of said cooling medium can be secured, and so, the temperature rise of the evaporator 11 can be controlled to a minimum level.

Title: Glow plug conduction controller
Inventor: YAMAMIYA OSAMU
IPC: F02P19/02
Filed: 1983-04-20
Abstract: PURPOSE:To maintain the glow plug temperature constant under stable heating as well as under quick heating, by feeding power to the glow plug upon dropping of capacitor terminal voltage below predetermined level while stopping power feed upon exceeding over predetermined level. CONSTITUTION:Through continuous power feed after closing of a key switch 2, the temperature will reach to approximately constant level of 900 deg. under the applied voltage in the range of 5-12V, then it is transferred to continual power feed to stabilize the temperature near to 800 deg.. After closing of the switch 2, a capacitor 9 is charged to drop the minus side terminal voltage thus to invert the outputs from a comparator 12 and another comparator 30 which is delayed through a delay circuit 15 to low level and to stop the continuous power feed to the glow plugs 3a-3d thus to remove voltage from the plus terminal 5. Consequently the capacitor 9 is discharged with the time constant similar with the natural cooling time of plug to increase the minus side terminal voltage of the capacitor 9 thus to feed power to the plug and to charge the capacitor 9 with constant current resulting in stabilization of the plug temperature.

Abstract: PURPOSE: To provide a handling apparatus, for inspection, whose production costs are reduced and whose adjusting and maintenance operability can be enhanced by a method wherein both driving mechanisms for rotation and for raising and lowering are installed on ground parts. CONSTITUTION: Regarding the inspection of a fuel rod N, the gripped and held fuel rod N is inserted into a hole inside a measuring unit S in which various measuring systems have been built. While the fuel rod N is being turned and raised and lowered simultaneously by a motor 8 for rotation and by a motor 7 for raising and lowering, various pieces of data are gathered. At this time, the rotational speed and the position in the circumferential direction of the fuel rod N are confirmed by a photosensor, and its raising and lowering speed and its position in the axial direction are checked by an encoder 9 or the like.  Since both the motor 7, for raising and lowering, which raises and lowers the nuclear fuel N and the motor 8, for rotation, which turns the fuel rod are situated on ground parts, it is possible to obtain a handling apparatus in which waterproof measures or the like are not required, whose production costs can be reduced and whose adjusting and maintenance operation becomes easy.

IPC: H01L21/3065
Filed: 1992-03-27
Abstract: PURPOSE:To improve yield of semiconductor devices and reliability by relaxing damages to semiconductor substrates caused by charge-up and radioactive ray. CONSTITUTION:A silicon oxide film 2, a charge trap layer 6 and a silicon nitride film 3 are formed on a silicon substrate 1. A resist 4 is formed on the silicon nitride film 3, and the silicon nitride film 3 is etched with etching gas 5. A positive trap is formed on the charge trap layer 6. Charge 9 possessed by the etching gas 5 disappears when it couples with the positive charge formed in the charge trap layer 6. So, charge will not take place at the boundary between the silicon substrate 1 and the silicon oxide film 2, resulting in no coupling destruction at the boundary or damage to the silicon substrate 1.
