Filed: 1989-06-20
Abstract: PURPOSE:To prevent the occurrence of air (bubbles) in resin by passing the resin in a hot blast furnace at a specific temperature before the process hardening the resin by ultraviolet-ray radiation. CONSTITUTION:In the manufacture of a battery filled with ultraviolet-ray hardening type resin 1 as an insulating member in a recess portion B formed between end sections exposed on the same plane of the positive electrode terminal 2 and the negative electrode terminal 3 of the battery, a process passing the resin 1 in a hot blast furnace kept at the temperature 120-150 deg.C is provided before the process hardening the resin 1 by ultraviolet-ways. The temperature is set to 120 deg.C or above, because the volume expansion required to scatter the air in generated bubbles from the resin 1 is not obtained at 120 deg.C or below. The temperature is set to 150 deg.C or below, because an insulating packing material 4 is thermoplastic resin and distortion may occur in the sealing state to reduce the airtightness of a seal section. The occurrence of bubbles is prevented, and long-term reliability can be improved.

Title: Paper feeder
Inventor: TOKUNAGA MITSUHIRO
IPC: H02N2/00
Filed: 1990-06-19
Abstract: PURPOSE:To afford drive force to a paper sheet through friction force so as to contrive miniaturization of a device by forming a paper feed surface of a vibration plate into a saw tooth shape cross section and also a lower surface of a paper retaining member into a shape almost corresponding to the paper feed surface of the vibration plate, in an ultrasonic motor which serves as a driving power supply of a paper feeder for a copying machine or the like. CONSTITUTION:Piezoelectric ceramics 21, 22, 23, 24 are fixed to a reverse surface of a vibration plate 11, and a paper feed surface 11a of saw tooth-shaped cross section is formed in an upper surface of the plate 11. An elliptic motion is generated in each mass point of the vibration plate 11 by applying phase-shifted sinusoidal voltage to specific combination of the piezoelectric ceramics 21 to 24. A paper retaining surface 13a of saw tooth-shaped cross section, agreeing with the paper feed surface 11a of the vibration plate 11, is formed in a lower surface of a fixed plate 13. When the vibration plate 11 is vibrated by interposing paper 12 between the vibration plate 11 and the fixed plate 13, the paper 12, obtaining drive force through friction force, is conveyed in the direction A. Since the paper 12 can be thus fed by the relatively thin plate-shaped fixed plate 13 in a condition that the paper is pressed to the vibration plate 11, a thin type device can be obtained without necessity for a large height member of rollers or the like.

Title: Powdery composition for tablet
Inventor: KOYAMA TAKAHIRO
IPC: A61K47/00
Filed: 1983-08-29
Abstract: PURPOSE:To provide the titled composition having excellent fluidity in the form of powder and giving a tablet having uniform weight and hardness, by compounding a drug component, a diluent and other additive with a disintegrant comprising a calcium cellulose glycolate having a specific bulk density. CONSTITUTION:A calcium cellulose glycolate having a bulk density of 550- 900g/l is used as a disintegrant for a powdery composition composed of a drug component, a diluent, a disintegrant and arbitrary additives. Although calcium cellulose glycolate is the most popular disintegrant for medicine, however, it has relatively poor fluidity in powdery composition, resulting in the lowering of the constant rate feed of the powder. It has been found that the use of a cellulose glycolate having high bulk density is effective to improve the powder fluidity and the constant rate feeding of the powdery composition to a tableting machine, and gives tablets having uniform weight.
