Title: Refrigerator
Inventor: ARAI KUNIO
IPC: F25D17/08
Filed: 1988-08-09
Abstract: PURPOSE:To utilize a portion of a dead space for laying a return duct, make the use of thick side walls unnecessary for the second cooling chamber, enlarge the effective content volume of the chamber, and improve the appearance of the refrigerator by passing a return duct at a position ranging with the damper. CONSTITUTION:The inside of a refrigerator 21 is divided, from the top downward, into a freezing chamber 22 as a first cooling chamber, a switching chamber 23 as a second cooling chamber, and a cold chamber 24 as a third cooling chamber with partitions 25a, 25b respectively for the separation. With use of a dead space at the sides of the damper taken into consideration a return duct 41 is passed at the position ranging with the damper 35. A dead space can thus be utilized effectively by forming a return duct therein. As a result, it becomes unnecessary for the side walls at the switching chamber 23 to be made thick and the effective content volume thereof becomes larger. The formation of the return duct 41 does not cause a decrease in the effective content volume of the switching chamber 23 but provides a large space, and moreover, resulting uniformity in wall thickness of the main body 21 lends itself to improvement in appearance of the refrigerator.

Title: Cassetteless quick photographing device
Inventor: IKETA YOSHIKAZU
IPC: G03B42/02
Filed: 1992-07-03
Abstract: PURPOSE:To easily take out X-ray film after photographing even when the degree of contact of the X-ray film is made high. CONSTITUTION:An upper plate 54 and a lower plate 51 are made of carbon fiber obtained by superposing plural pieces of cloth of carbon fiber and pressurizing them with adhesive. Rigidity is set higher in a film inserting direction than in a direction perpendicular to the filmy inserting direction on the upper plate 54, and it is set higher in a horizontal direction than in a vertical direction on the lower plate 51. By making the rigidity of the upper and the lower plates 54 and 51 interposing the X-ray film 7 between them strong, the plates 54 and 51 are curved and brought into contact with each other when space between the plates 54 and 51 is made a vacuum state, so that contact time is shortened. Since the lower plate 51 is largely curved in the case of taking out the X-ray film 7, the contact between the lower plate 51 and the X-ray film 7 is quickly released.

Title: Antistatic agent
Inventor: INOBE ATSUYOSHI
IPC: C09K3/16
Filed: 1982-11-15
Abstract: PURPOSE:To provide an antistatic agent containing anionic surfactants having univalent and divalent cations and exhibiting an excellent antistatic effect without detriment to the thermal stability. CONSTITUTION:The antisatic agent contains (A) anionic surfactant with a univalent cation (e.g. sodium alkanesulfonate) and (B) anionic surfactant with a divalent cation (e.g. calcium alkanesulfonate). The combined use of (A) which is a common antistatic agent and (B) which scarcely shows an antistatic effect by itself, gives a synergistic antistatic effect and can reduce the amount of the univalent metal salt which relatively impairs the thermal stability of plastics, to a great extent. Thus the thermal stability of plastics is not impaired and bleeding-out is also inhibited as a result of the improved compatibility of the agent with plastics increasing the durability of the antistatic effect.

Abstract: PURPOSE:To reduce the bonding area by arranging a slit at the front of a capillary as a bonding tool. CONSTITUTION:A slit 14 is arranged in a longitudinal direction of a capillary 12 and it shapes as if it divides the capillary in the longitudinal direction. Through this capillary 12, a wire 15 is inserted. Also, the capillary 12 is supported by a clamper 16. A driving part 34 is composed of, e.g., piezoelectric element. When no voltage is applied to the driving part 34, the clamper 16 is open and the degree of closing of the clamper 16 can be changed by intensity of the voltage applied to the driving part 34. By such constitution, there is no space between an internal diameter of a front end of the capillary 12 and a diameter of the wire 15 so that the area which the front end of capillary 12 pushes the ball formed at the front end of the wire 15 enhances and the pressure-contact property is improved. Accordingly, if the ball is formed to be small, the wire bonding with the desired strength of pressure contact can be done.
