Title: Cooling device of projection type crt
Inventor: ICHIJIYOU TAKASHI
IPC: H01J7/24
Filed: 1984-02-14
Abstract: PURPOSE:To cool a fluorescent screen and a face plate more effectively and improve the quality of a projected image by providing the first closed space sealed with a refrigerant in front of the face plate and providing the second closed space for cooling the refrigerant inside or outside the first space to form a double structure. CONSTITUTION:The heat generated on a fluorescent screen 2 is absorbed by the first refrigerant in the first closed space 12 via a face plate 3. The temperature distribution of the face plate 3, i.e., fluorescent screen, is made uniform by the thermal conduction of the first refrigerant and the thermal conduction of natural convection. In addition, the heat of the first refrigerant in the first closed space 12 is absorbed by the second refrigerant in the second closed space 16 located inside or outside the first closed space 12, thereby the cooling effct of the face plate 3 and fluorescent screen 2 is improved. Accordingly, the fluorescent efficiency is largely improved depending on the types of phosphors used, and the brightness of a projected image can be widely increased.

Title: Supply unit for solder in automatic soldering device
Inventor: ATOBE TAKASHI
IPC: B23K3/06
Filed: 1982-02-19
Abstract: PURPOSE:To prevent defective soldering in an automatic soldering device, by providing a means for detecting the clogging of the device with solder. CONSTITUTION:Wire solder 2 wound around a roll 1 is fed from the spacing between a gear 3 and a gear 4 and is supplied to a tube 5 when both gears are rotated by a motor. When the solder 2 delivered from the tube 5 is melted insufficiently on account of oxidation of an iron tip 6 or the like upon contacting the iron tip 6, the wire 3 bends between the gears 3, 4 and the inlet of the tube 5 and contacts detecting plates 7 and 8. As a result, electric current flows from the plate 7 to the plate 8 and operates a buzzer 11, thereby announcing  the abnormality that the solder 2 fails to come out from the tube 5.

Title: Power transmission mechanism having pinion and rack
Inventor: TOUKAWA YOUICHI
IPC: F16H55/26
Filed: 1983-02-18
Abstract: PURPOSE:To prevent the pi (pi) from entering in the feed amount of a rack so that the difficulty in selecting the number of teeth is eliminated, by setting the moving amount of the rack corresponding to one tooth pitch rotation of a pinion, and as well by forming a rack with a pressure angle corresponding to the afore-mentioned moving amount. CONSTITUTION:A rack tooth surface (ab) which is meshed with an involute curve (aAc) having a base circle (Dg) moves, when the curve (aAc) rotates in the direction E and reaches a curve (a''b'B'), to a rack tooth surface (a''b'B') in the direction F which corresponds to the movement of the curve (aAc). By estimating that the involute curves (aAc), (a''b'B') are the adjacent tooth shapes of a pinion of standard gear type, the moving distance of the rack changes as such bb', BB' when the pinion gear rotates by one tooth pitch, and therefore, the moving distance may have an arbitrary value by changing the pressure angle of the meshed rack tooth surfaces. With this arrangement the pressure angle is changed while the normal pitch of the rack is maintained, and, as a result, the meshed pitch circle diameter of the pinion is changed to prevent the affection of pi (pi).
