Title: Stone grinding machine using bit
Inventor: INOUE KOUTAROU
IPC: B28D1/08
Filed: 1979-08-11
Abstract: PURPOSE: To prevent dust and perform low-power and quiet cutting and grinding, by rotating both end portions of a straight or cross cutter bit used in a rotating machine drill to scrape off a stone and pouring water through the central bores of the bit and its bit rod.  
     CONSTITUTION: A main body A is lifted by an up-and-down rod 22 which is raised by rotation of a handle mounted on a pinion shaft. The up-and down rod 22 is lowered to the position where a stone is to be ground and clamped and fixed. It is required for a group of bits to grind always a stone face that an advancing supporting rod is first attracted by a manget piece 25 of induction ferrite on one side to contact a guide rail 24 on one side, and then a nut is turned back by its abutting in advacing a ferrite magnet 26 for rotation and the main body A descends through supporting rods. By the way bits are supplied with water through bit shafts.

Title: Tuning detector of radio receiver
Inventor: GOMI SHINTAROU
IPC: H03J7/28
Filed: 1984-05-23
Abstract: PURPOSE:To secure the extremely exact synchronism between a radio receiver and a center frequency by using a PLL consisting of a voltage control crystal oscillator which oscillates with an intermediate frequency and detecting a tuning point from an AND obtained between the output of a reception level detector and the output obtained when the PLL is locked. CONSTITUTION:A certain frequency is received in a sweep mode by a receiver and put into the characteristics of an intermediate frequency band filter 6. In such a case, a level detector 25 is actuated. Then a VCXO22 is locked when a local oscillator 4 is swept and synchronized with a frequency fo, and a search stop signal is delivered to a terminal 27 owing to an AND obtained between the output of the detector 24 and the output of the detector 25. If the fo is set at 10.7MHz, the VCXO22 is locked only when the intermediate frequency is set within fo+ or -1kHz. Thus it is possible to deliver the search stop signal at an exact tuning point.
