Title: Buffer structure for holding electronic implement or the like in game machine
Inventor: KUREOKA TSUTOMU
IPC: A63F7/02
Filed: 1992-05-14
Abstract: PURPOSE:To prevent electronic implements or the like from the degradation of performance, defective operation, etc. CONSTITUTION:Planar U-shaped slits 38 are formed in four corners of a bottom plate in a receiving case C so that approximately U-shaped buffer pieces 39 preferably elastically deformable in the inward and outward directions are molded. Projecting boss parts 40 are provided integrally on the inner surface of the respective buffer pieces 39 at the free end side. Drive circuit base board 25 of a pattern device D is fixed to the four boss parts 40 by screws. Mounting pieces 33 are molded respectively integrally with both left and right sides of an opening surface of the receiving case C. The receiving case C is fixed to the rear surface of a game board by screws while the mounting pieces 33 abut against the rear surface. As a result, when the external vibration and impact act on the game board, the impact or the like is effectively attenuated and absorbed by the cushion action of a buffer holding part 37 so that the pattern device D has the motion restrained and reduced to faint motion without being largely fluctuated.

IPC: C07C63/26
Filed: 1977-12-13
Abstract: PURPOSE: High-purity terephthalic acid is produced through simple procedures by oxidizing p-tolualdehyde in an aqueous medium by oxygen gas, purifying the resulting crude terephthalic acid by treating with hydrogen and recycling and reusing the remaining mother liquor as the solvent.  
     CONSTITUTION: p-Tolualdehyde is continuously oxidized by an oxygen-containing gas in an aqueous medium in the presence of bromine ion such as hydrobromic acid and the resulting crude terephthalic acid is separated from the reaction mixture. Then the terephthalic acid is dissolved in water and catalytically treated with hydrogen in a temperature range from 200 to 330°C and the aqueous solution is cooled to precipitate purified terephthalic acid, which is separated. 4-CBA, a by- product, is converted to p-toluic acid by hydrogen reduction and remains in the mother liquor in the form of p-toluic acid which will be later converted to terephthalic acid. The mother liquor is recycled and reused as a solvent for the oxidation.  
     EFFECT: The total yield of terephthalic acid increases.

Abstract: PURPOSE:To improve analytical accuracy by preventing the fluctuation of the temp. of a reaction line by using the radiation heat from a light source. CONSTITUTION:The light source device 20 having a light source lamp 33 is disposed in the position apart from a reaction line which is a path for conveying a reaction tube 8, i.e., on the rear of a base 32 to prevent the temp. of the reaction line maintained at a constant value from being affected by the heat generated from the device 20 in order to measure the absorbancy of the liquid to be tested formed by the reaction between the sample and reagent dispensed into the tube 8. The radiation light of the lamp 33 is projected through a filter device 21 and a branch fiber bundle 22 to the tube 8 existing in the photometric position. The light transmitted through the tube 8 is detected by a photodetector 23g and is analyzed by an amplifier 40g. Since the photodetector and amplifier are disposed in the constant temp. space existing above a jacket 29, the temp. drift is decreased and the analytical accuracy is improved.

The class B current amplifier 3 is energized by a high voltage DC power supply whose neutral point potential connects to ground and amplifies an input signal in the efficient class B operation. On the other hand, the class A current amplifier 4 is energized by a low voltage power supply whose neutral point potential is inolated form ground and driven while receiving an idle current being a half of a peak value at non-signal. In this case, an output of the class B current amplifier 3 is supplementarily injected to the neutral potential of the low voltage power supply, and the class A current amplifier 4 amplifies the input signal in the class A operation with a minute low loss. Thus, the current amplifier circuit used singly with a low loss and a high efficiency with comparatively inexpensive constitution whose output distortion characteristic is excellent is realized.
