Title: Oxide hot cathode
Inventor: OGAWA SHINJI
IPC: H01J1/20
Filed: 1989-02-13
Abstract: PURPOSE:To improve longevity of a cathode in operation at high current density by adding at least one species among Gd oxide, Sn oxide, Ta carbide, Ti carbide, and Li, to an oxide layer. CONSTITUTION:For an oxide hot cathode having an oxide layer composed of an oxide hot cathode, especially of an oxide alkali earth metal, at least one species among Gd oxide, Sn oxide, Ta carbide, Ti carbide, and Li is added to the oxide layer. Temperature change in the oxide when current density is enhanced, or increase in temperature by Joule heat, can thereby sufficiently suppressed. Longevity of the cathode can thus be achieved.

Title: Video tape recorder
Inventor: MIZUKAMI MINEO
IPC: G11B20/06
Filed: 1983-02-28
Abstract: PURPOSE:To eliminate the interference to the sound signal by increasing the recording level of the sound signal which works synchronously with the vertical blanking pulse of the luminance signal and receives the modulation of frequency during a working period. CONSTITUTION:A pulse generating circuit 16 is connected to a vertical synchronizing separator 17 and produces a pulse synchronous with a vertical blanking pulse. This pulse is supplied to a changeover switch 15c of a pre-emphasizing circuit 15, and buffer circuit 13 and 14 are connected via a signal line 15a during a vertical blanking period. Therefore the sound signal produces a difference of amplitude equivalent to a gain drop set at an attenuator 15d between the blanking period and other periods. Thus it is possible to avoid the S/N reduction due to the interference of the leaked signal even though the video sweep signal, etc. are partially leaked into the band of the sound signal.

Title: Method and apparatus for stone dressing
Inventor: SAEKI YASUTERU
IPC: B28D1/00
Filed: 1991-02-01
Abstract: PURPOSE:To dress stone automatically and accurately by measuring in advance the shape and size of the vicinity of a dressed part of predressed stone and processing the stone while moving a dressing tool along the measured shape. CONSTITUTION:In the case where rounding-off work is performed to a head part of rectangular stone by utilizing a stone dressing apparatus 1, a base material fixed onto a pallet 6 is mounted on a dressing table 15 to measure an outer shape of a dressed part. Then, a probe is removed, and grinding is done by using a diamond grindstone 20 whose dressing surface is formed into a curved concave surface. Since the rounding-off at the head part is done along the outer shape of the base material, the fine appearance of the dressed stone thus obtained is not spoiled even in the case where the base material has slight strain. Furthermore, since it is not necessary to pregrind a base material into an accurately rectangular shape, any losses of labor are not required. Moreover, the size of a finished product can be made as large as possible, and it is possible to furnish the finished product with a beautiful appearance.

Title: Testing circuit for wiring continuity
Inventor: YOSHINO SUMIYOSHI
IPC: G01R31/02
Filed: 1984-02-24
Abstract: PURPOSE:To lower a pulse voltage and to reduce the size of a receiver, and also to reduce noise by connecting electric equipment to each earth line between output terminals of a resistance switching circuit and a constant voltage output circuit. CONSTITUTION:A relay switch 11 for control is normally open and values of respective elements are so set that the voltage VT at a terminal V is as shown by an expression (ZD1, ZD2, and ZD3; Zener voltage and RZ; composite impedance of terminal equipment 13-); and the transistor (TR) 17 of a terminator (resistance switching circuit) 21 turns off and a TR20 turns on, so the output terminal 6a of a comparing circuit 6 is still at a low level. If there is a break of wiring to terminal equipment 13, the voltage VA at a point A is VA>VT> VR and the comparing circuit 6 outputs an abnormal conduction signal. When terminal equipment is put in operation, the switch 11 is closed to apply 24V to the terminator 21, and the TR17 turns on while the TR20 turns off, so a power line 24 is held at 24V and the terminal equipment 13 operates as specified.
