Title: Cooling structure for air cooled electronic device
Inventor: YAMAZAKI SUSUMU
IPC: H01L23/467
Filed: 1988-11-11
Abstract: PURPOSE:To effectively cool heat generators such as IC, LSI for forming an electronic device, to reduce and simplify the cooling structure of the device, and to reduce its noise by providing a gap at the side faces of board group, blocking the flow at the downstream side of the gap, and feeding air fed at the upstream side of the gap between the boards. CONSTITUTION:Passages S1, S2 are provided outside a board 2 in an electronic device, and air control plates 11, 12 are provided in the passages S1, S2 in the direction of the board group. A case 4 has an air intake opening plate 5 and a cooling fan 3. When the fan 3 is operated, cooling air 6a is fed from the opening 5 as designated by 6b. The air is then fed between the board as designated by 6d, and since air velocity 6d is small due to the draft resistance of the array of semiconductors between the boards. No resistance exists in the passages S1, S2 out of the boards, and air velocity vs is large. The flow 6f outside the boards is gathered to the position of a hole 13 by the plate 11, the flow 6f' through the hole 13 is fed as designated by 6f'' between the boards to increase the windage at the boards. Thus, IC, LSI, etc., can be effectively cooled.

Abstract: PROBLEM TO BE SOLVED: To make prints of plural widths without exchanging magazines, applying a load on a development processing means and taking time to switch the width of the print by cutting off a developed photosensitive material for the print with a prescribed width. SOLUTION: A photographic printing paper after being exposed passes through a paper development processing part 4, to be developed and then, is fed to a post-processing part 550. In this post-processing part 550, the position in a width direction of the print is placed in a fixed position by a guide provided between a roller 559 and a counter roller and the photographic printing paper is cut off with the prescribed width by a prescribed width cutter 563. Concretely, the prescribed width cutter 563 cuts a cut/fed postal card size print of A5-size into two postal card size prints of the prescribed width. The counter roller facing the prescribed width counter 563 is used as a table for holding the photographic printing paper with respect to the prescribed width counter 563. Further, pressing rollers press the photographic printing paper on both sides of the cutter 563.

Title: Surface mounting type piezoelectric oscillator
Inventor: NAKAMURA JUNICHIRO
IPC: H03H9/19
Filed: 1989-10-31
Abstract: PURPOSE:To improve the impact resistance, the resonance characteristic and the aging characteristic by folding a metallic plate in two to stick it to a holding electrode formed on the plate surface of a base made of an insulating material and holding a crystal piece provided with an electrode on the plate surface and airtightly enclosing this base with a cover together with the crystal piece. CONSTITUTION:A holding electrode 12 is formed on the upper face of a base 11 made of an insulating material, and a metallic plate 14 folded in two is stuck on the holding electrode 12, and the end part of a crystal piece 15 is placed and stuck on the metallic plate 14. The upper face of the base 12 is covered with a cover 16 and is airtightly enclosed. Though an impact from the external acts on the base or the base 11 is thermally expanded by the change of temperature, its stress does not directly reach the crystal piece 15 because the metallic plate 14 folded in two functions as a buffer material. Thus, a piezoelectric oscillator is obtained which is superior in impact resistance and has a satisfactory resonance characteristic and is superior in aging characteristic.

Title: Liquid crystal display device
Inventor: KIMURA AKIRA
IPC: G12B11/00
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration in visibility of a liquid crystal display even when external light is reflected in by converting transmission light to a display color with a liquid crystal protection filter arranged in front of a liquid crystal display element, coloring the reflected light from the outside and making it visible with its color difference. SOLUTION: Amber color light 15 from a light bulb 12 transmits through a diffusion plate 13 to be diffused (15'). In such a case, since the diffusion plate 13 is transparent, its color isn't converted, and is the amber color as it is. Then, the amber color light 15' makes the display of a character and a figure visible by passing through the liquid crystal display element 11, and thereafter, though it transmits through the liquid crystal protection filter 14 (15", 15'''), and it arrives at the eye 16 of a viewer, in such a case, since the liquid crystal protection filter 14 is colored to a blue color, the amber color light 15'' is converted to the white color light 15''', and thus, the character and the figure are liquid crystal displayed by the white color.

Title: Optical card device
Inventor: HORIGUCHI TOSHIO
IPC: B42D15/10
Filed: 1991-10-30
Abstract: PURPOSE:To make it possible to set optimum waiting time by detecting the point when a relative transfer speed of an optical card and an optical head comes to zero and then allowing a tracking state to detect the arrival of a specified state and jumping an optical spot. CONSTITUTION:After the completion of seek, an optical card 11 moves to an optical head 12 relatively and linearly where the record and reproduction of the card 11 to an objective track are carried out and a status signal is read by a drive controller 21 by way of a second VCM drive circuit 26. The movement of the shuttle 23 within a fixed time is decided and detected by a relative speed 'zero' of the head 12 and the shuttle 23 based on a specified distance and below about the movement of the shuttle. After this detection is over, the controller 21 waits until the detected signal turns to the specified value and below from a tracking-state detection signal equivalent to vibration or the like from a track deviation detection circuit 20 and then outputs a detection signal and carries a track jump of an optical spot. This construction makes it possible to set an optimum waiting time which varies with a device and carry out definite track jump in the shortest time.
