Title: Diode for protecting breakdown by surge
Inventor: KUBO HIROSHI
IPC: H01L29/861
Filed: 1984-11-27
Abstract: PURPOSE:To prevent the breakdown of a junction by reducing currents flowing from a diffusion region surrounded even through the application of an inverse voltage surge is made by contacts formed at each corner section. CONSTITUTION:Contacts 11 represent contacts with metallic wirings 5 shaped at several corner sectionn of a P<+> diffusion region 3. The arrows (a), (b) represent the directions that currents flow when an inverse voltage surge is applied. Currents by the arrow (b) are reduced because of a resistance section in the P<+> diffusion region 3, and currents by the arrow (a) are also minimized because of a large distance L between an N<+> diffusion region 2 in theresistance section and the P<+> diffusion region 3. Accordingly, a calorific value by currents is also decreased, thus easily preventing the generation of the breakdown of a junction.

Title: Reel for tape cassette
Inventor: SHINOHARA KAZUYOSHI
IPC: G11B23/087
Filed: 1985-11-08
Abstract: PURPOSE:To improve the accuracy on the cylindrical face of the outer periphery of a core and check piece by constituting so that the tape is fixed by being pinched in the radial direction of the core between the projecting part and gap and that no compression force in the peripheral direction is applied on the tape by the notch part and check piece as well. CONSTITUTION:The length in the peripheral direction of a check piece 14 is slightly shorter than that of a notch part 12 so that a tape 13 is not compressed in the peripheral direction. The pair of leg parts 14a, 14b extending toward the bottom part of the notch part 12 and the projecting parts 14c, 14d projecting to the external direction from these tips are provided on the check piece 14. The tape 13 is fixed to a core 11 receiving the compression force in the radial direction of the core 11 between the projecting parts 14c, 14d at the tip of the leg parts 14a, 14b of the check piece 14 and the gaps 12a, 12b of the notch part 12 which receives the projecting parts thereof. The thickness of the projecting parts 14c, 14d is set slightly larger than the value subtracting the thickness for two sheets part of the tape 13 from the width of the gaps 12a, 12b, therefore. In this way no step on the cylindrical face is caused due to the deflection because of the check piece receiving no positive force in the peripheral direction.

Title: Adaptive filter system before coding of picture data
Inventor: ONO MITSUNORI
IPC: H04N19/136
Filed: 1990-09-20
Abstract: PURPOSE:To reduce the produced information quantity or to improve the picture quality under the condition of constant transmission speed by deciding a moving picture degree or a still picture degree of a picture and changing a band width of a filter adaptively in response to the moving picture degree or the still picture degree. CONSTITUTION:Since a moving area is enough to have lower resolution than that of a still picture area depending on the human visual sense characteristic, when a deciding circuit 2 decides and area to be a moving picture area, a band width revision means 3 revises a band width of a filter 1 marrow (selection of a filter having a narrow band width) to reduce the production information quantity. On the other hand, when the deciding circuit 2 decides an area to be a still picture area, the band width of the filter 1 is revised to be width (selection of a filter having a wide band width) to limit the band. Since the band width of the filter is adaptively changed in response to the moving picture degree or the still picture degree in this way, the filtering processing is applied in response to the still picture area and the moving picture area, then the production information quantity is reduced and the picture quality is improved under the condition of constant transmission speed.

Title: Air bleed for carburetter
Inventor: OGAWARA YASUYUKI
IPC: F02M19/06
Filed: 1993-09-13
Abstract: PURPOSE:To obtain minute particulates of fuel in an air bleed of a carburetter by reducing a size of each bubble mixed with the fuel. CONSTITUTION:A bleed pipe 36 is inserted into a fuel passage for supplying the fuel to a discharge port inside a venturi. A breed port 39 having a drop-like shape formed with a sharp portion is formed on a downstream side of the fuel passage, for communicating the fuel passage with an air passage 38 inside the bleed pipe 36. Air bubbles are mixed with the fuel suctioned by the venturi negative pressure and passing the fuel passage, which air is supplied from the air passage through the bleed port 39. The bubbles are cut by large shearing force applied by the sharp portion 39a of the bleed port 39. The size of each bubble is thus reduced and minute particulates of fuel are obtained.

Title: Temperature controller for electric heater
Inventor: KATAYAMA HISAYASU
IPC: H05B3/00
Filed: 1985-11-08
Abstract: PURPOSE:To vary the temperature of a heating element in response to a room temperature and to always secure a pleasant level of temperature, by generating the temperature setting voltage with serial connection of plural diodes and resistances and varying said temperature setting voltage according to the change of the forward voltage of the diode produced by the change of the room temperature as well as the number of conductive diodes. CONSTITUTION:The temperature setting voltage VS is minimum at the position 1 of a changeover switch 41 and diodes 36-40 all conduct at the position 1 of the switch 41. Then the diodes 37-40 conduct at the position 2 of the switch 41. In such a way, the number of conductive diodes are successively reduced. Then the forward voltage is increased with diodes 36-40 as the room temperature is reduced. While the voltage VS is reduced with the temperature of a heating element 2 is increased. Thus the temperature of the element 2 is varied in response to the room temperature. Therefore it is no required for an operator to increase the setting level of temperature in response to the drop of the room temperature.

Title: Variable displacement swash plate type compressor
Inventor: OTA MASAKI
IPC: F04B27/10
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To restrain looseness of a fitting part by a thermal expansion difference from a rotation transmitting part composed of iron metal, and improve reliability together with productivity and functionality by fitting a swash plate main body and a swash plate guide by press-in, and arranging a relative rotation preventive means between both. SOLUTION: A swash plate element 20 is composed of a swash plate main body 21 composed of aluminium metal and a swash plate guide 22 composed of iron metal. Since the swash plate main body 21 and the swash plate guide 22 are formed as separate bodies, not only work of both is facilitated but also an optimal base material uninfluenced by heat in a crank chamber 5 can be combined. A fitting projection part 22a of the swash plate guide 22 is pressed and fitted to a fitting hole 21b of the swash plate main body 21 with a prescribed fastening margin.  In a severe operation condition, powerful torque also acts on a press-in fitting part of the swash plate main body 21 and the swash plate guide 22, but since the swash plate main body 21 and the swash plate guide 22 are co-fastened by a small screw 26 together with a counterweight installed on these, looseness of the press-in fitting part can be completely and reliably prevented.
