Title: Manufacturing process for discharge lamp
Inventor: YAMAZAKI HITOSHI
IPC: H01J9/24
Filed: 1982-12-06
Abstract: PURPOSE:To enable a glass tube with the strength increased due to its configuration into U-shape to be produced irrespective of its curvature, by heating and softening two glass tubes each of which has its one end closed, thereafter pressurizing the insides of the tubes, forming opening parts in order to connect them to each other, putting them into a molding tool, and molding them into the predetermined shape. CONSTITUTION:The facing parts (parts to be connected) in the vicinity of the closed parts of two glass tubes 1 are locally heated with a gas burner 6, after that, when they are softened, air is fed into respective glass tubes 1 through air- feeding inlets 33. When the parts to be connected to each other project outward and the tips of the projecting parts are perforated by the pressure of air, a holder 22 is moved in order to connect the glass tubes 1 to each other. The vicinity of the connected part 1a is heated with the gas burner 6, the softened part is covered with a molding split die 55, and air is fed thereinto from the air- feeding inlets 33 in order to pressure-mold the inside of the glass tubes. By doing this, the wall-thickness of the curved part of glass can be controlled without difficulty, and consequently, a U-shaped fluorescent lamp having the sufficient strength can be easily produced.

Title: Nickel-chromium plating method
Inventor: ISHIGURO FUMIYASU
IPC: C25D5/12
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To obtain nickel-chromium plating showing an appearance similar or close to the case in which sexivalent chromium is used by using trivalent chromium. SOLUTION: The grain size in the surface of a nickel plating layer is regulated to the range of 10 to 1,000nm.

Title: Impeller molding made of fiber-reinforced resin and mold for forming impeller made of fiber-reinforced resin
Inventor: IIO HIKARI
IPC: B29L31/08
Filed: 1993-08-30
Abstract: PURPOSE:To prevent the generation of noise by setting the axial hole diameters of axial hole diameter control parts, provided at both end parts of the contact part, with a shaft, of the axial hole inner surface of an impeller, to the fixed dimensional tolerance to the diameter of the shaft to be fitted, and forming the impeller without the machining of the axial hole. CONSTITUTION:The axial hole diameters of a back face side hole control part A of 3mm or more and a boss side axial hole diameter control part B of 2mm or more provided at both ends of the contact part, with a shaft, of the axial hole inner surface of an impeller compact made of fiber-reinforced resin are set to -0.015-+0.020mm in relation to the diameter of the shaft to be fitted. As a result, the generation of noise is prevented without requiring the machining of the axial hole at the beginning, so that dimensional accuracy can be disregarded as to the axial hole diameters of the minimum required axial hole accuracy control parts and the axial hole diameter of a part unconcerned with noise. This results in dispensing with the pin diameter correction of a metal mold to the fluctuation of the axial hole diameter caused by the inter-lot dispersion of a material characteristic, for instance, optimizing the cut part dimension of the back plate side end face minimize the dispersion of the axial hole diameter, and the like, obtaining the inexpensive impeller and its mold.

Title: Speed controlling system of magnetic tape device
Inventor: KOYAMA YOSHIAKI
IPC: H02P29/00
Filed: 1981-12-29
Abstract: PURPOSE:To control the travelling speed of a magnetic tape by integrating and constant-multiplying the deviation information between the travelling speed information and the target speed information of the magnetic tape for a speed controlling system of a magnetic tape device of a reel-to-reel system, and generating a virtual error information, and adding it to the deviation information based on the added value. CONSTITUTION:The external fluctuation due to the tension, friction, etc. of a magnetic tape emerges to a deviation Ne, i.e., the output of a comparison arithmetic circuit 15. Such deviation fluctuation is absorbed by an integration circuit 16, and the integrated value is added to the deviation Ne by an adder circuit 18. Therefore the degree of deceleration compared with the target speed of a driving motor 11 is eliminated by an increment of the driving current due to the integrated value. On the contrary, if the motor 11 is accelerated excessively, the degree of acceleration is also eliminated by a decrement of the integrated value. As a result, the tachopulse period N produced by the revolution of the motor 11 is set closer to the target value No.
