Title: Automatic channel selection device in common use as manual operation
Inventor: OHASHI TAMAKI
IPC: H03J7/16
Filed: 1986-06-05
Abstract: PURPOSE:To prevent malfunction by depressing a knob provided to a manual shaft of a manual tuning mechanism so as to close a switch of a motor drive circuit thereby disconnecting the interlocking relation between the manual shaft and the drive system comprising a motor. CONSTITUTION:In applying the automatic tuning, the knob 57 is depressed. Then the manual shaft 18 is forwarded against its restoring spring 61, the meshing between a gear 19 of the manual shaft 18 and a gear 20 of the operating shaft 22 is released and the switch 52 is closed at the tip of the manual shaft 18. Thus, a motor 50 and an electromagnetic operation body 54 are energized respectively and a planetary gear mechanism 51 is rstricted in its drive delivery state. Thus, no automatic tuning is applied so long as the manual shaft of the manual operation tuning mechanism is not depressed and the drive of the manual shaft of the manual tuning mechanism is not driven.

Title: Speed detecting apparatus
Inventor: SAWAMURA MITSUJIRO
IPC: G01P3/481
Filed: 1990-05-21
Abstract: PURPOSE:To detect a speed correctly even if the phase difference is largely shifted from the specified phase difference by using either of the two-phase signals outputted from a rotary encoder, generating new two-phase signals having the frequencies which are 1/2 of the original frequency, using the two- phase signals for a pulse generating circuit, and detecting the speed. CONSTITUTION:The SELECT of a pulse-frequency dividing circuit is made to be '0' so as to compute a speed (f). When the speed becomes faster than a preset speed f0, the SELECT is made to be '1'. The outputs of AND gates 25 and 27 become '0'. Signals SA' and SB' whose frequencies are divided into 1/2 are outputted. A microcomputer 18' detects the speed (f) by the following expression: f = 21 N1/T1*SIGN(f) (wherein SIGN(f) is the speed (f) when the SELECT is '0'). The signals SA' and SB' are signals obtained by simply dividing the frequency of an A-phase pulse signal SA. Since the rotating direction is not considered at all, the rotating direction when the SELECT is '0' is used. When the speed becomes smaller than the preset speed f0, the SELECT becomes '0' again, and the speed is detected. The preset speed f0 is made to be located within a speed range wherein the two-phase signals SA and SB keep the phase difference of 90 deg..

Abstract: PURPOSE: To remove the occurrence of distortion by equipping a coil mold body with a projection-shaped engaging part to be engaged in specified direction and a tapered part in specified direction, and equipping a yoke with a slot to engage with the coil mold body, and a called part, being plastically deformed while abutting on the tapered part. CONSTITUTION: When a calking claw 11a is inserted into a mounting hole 15, the tip of the calking claw 11a comes out to the topside of the mounting hole 15. Next, when a pair of calking claws 11a inward calk by cutting pliers or the like, the calking claws 11a bends inward at the section of a groove 11b for calking after an engaging groove 11a abuts on the body 32. The calking claws 11a abuts on the tapered part 15a when bending inward, and shifts along the taper, and the whole of a yoke 11 shifts to the position of the calking claw 11a. By the yoke 11 shifting right, the engaging groove 11c engages with the projection-shaped engaging part 14, and the engaging hole 11e engages with the projection-shaped engaging part 12. Magnetic resistance can be reduced by this calking processing.

Title: Analog/digital signal converter
Inventor: NAKATSUKA TAKASHI
IPC: H03M1/38
Filed: 1989-05-24
Abstract: PURPOSE:To prevent the register circuit of an A/D converter from malfunctioning and to easily transfer data to and from an external equipment by using an AND circuit and a flip-flop circuit and generating a flip-flop network driving clock only during A/D conversion. CONSTITUTION:When a start signal (C, CMD) is inputted, a flip-flop network 310 starts operating. At this time, a signal (EOC) indicating that the conversion is in process varies from 'L' to 'H'. Consequently, the flip-flop driving clock is generated in synchronism with an external clock when the EOC is at 'H' since the EOC and external clock (EX, CK) are ANDed. Further, when the EOC varies from 'H' to 'L' after the conversion, the driving clock is not generated. Further, when the EOC is at 'L' during the conversion and at 'H' at other times, the inversion signal of the EOC is used for similar operation, thereby obtaining the A/D converter which generates an internal driving clock only during the conversion.
