Abstract: PURPOSE:To display a REC review picture so as to distinguish a through picture from the REC review picture clearly when the REC review function is employed in an electronic still camera. CONSTITUTION:A signal subject to FM modulation by a recording processing circuit 1 is recorded on a prescribed track of a video floppy 3 by a recording/ reproduction circuit 2. When the mode is set to the REC review mode, a picture recorded is read from the track succeedingly. Simultaneously, a character pattern representing the REC review picture is sent to a mixer circuit 6 by a character generator 12. A video signal to be read and the character pattern are mixed in the mixer circuit 6 and the mixed signal is displayed on a video finder. Thus, a photographer recognizes it that the displayed picture is a REC review picture.

Title: Optical video disk recorder
Inventor: HIOKI TOSHIAKI
IPC: H04N5/92
Filed: 1988-04-07
Abstract: PURPOSE:To cancel noise generated in an FM video signal by separating an FM video signal equivalent band from an output of amplitude limiting of a frequency multiplex output and amplitude-limiting its low band signal again after processing of subtraction. CONSTITUTION:An MUSE signal is FM-modulated in an FM modulator circuit 1 and inputted with a pilot signal to an adder circuit A. An added output is inputted to a 1st limiter 2, where an amplitude limiting is carried out, and passed through a BPF (band pass filter) 3, where high frequency components and their side components of the pilot signal and the FM video signal carrier are removed, so that disused components are only side components on both sides. On the other hand, the pilot signal is conformed with a delay amt. of the output of the BPF 3 by a delay circuit 4 and inputted together with the output of the BPF 3 to a subtractor circuit S. By this method, the FM video signal comprising the disused components and the negative-phase pilot signal are frequency-multiplexed, and the disused components generated on the side of high band are removed via a 2nd limiter 5 and an LPF 6. Consequently, the noise generated in the FM video signal can thus be cancelled.

Title: Castel lated nut fastening split cotter pin positioning detecting socket
Inventor: AMASAKA TADAO
IPC: B23P19/06
Filed: 1988-04-08
Abstract: PURPOSE:To prevent increase of size and to prevent the occurrence of poor contact to a slide part by a method wherein a power source mounted on the case side and an emission element are electrically interconnected through bearings, and a signal output part disposed on the case side and a collection element are electrically interconnected through the bearings. CONSTITUTION:A power from a power source 13 is fed to an emission element 81 through bearings 21 and 23 and the emission element 81 emits light. Meanwhile, light emitted from the emission element 81 through coincidence of the split cotter pin groove of a castellated nut with the through-hole of a bolt is inputted to a collecting element 82 to photoelectrically convert it, and an electrical signal therefrom is fed to a signal output part 12 on the case 10 side through the bearings 21 and 23. This constitution eliminates the need to mount a new slide part for tie-in of an electrical signal between the rotation side and the fixed side, and prevents complication of a device and increase the size of the device, and in turn reduces limitation on a space. Besides, the bearings 21 and 23 are used for tie-in of the electric signal between the rotation side and the fixed side, resulting in suppression of wear.

Abstract: PURPOSE:To reduce the number of parts and apply a brake power on a reel by a simple structure by allowing the side surface of an edge plate of a reel to press contact a brake member when a supporting body is put into a sideway- fall-down state where a supporting shaft is directed in the vertical direction, in a taking-up device for a cord, etc. CONSTITUTION:When a cord 14 wound on a reel 11 is pulled out, a supporting body 1 is installed in sideway-fall-down state on an installation surface A so that a supporting shaft 6 is directed in the vertical direction. In this case, the whole is supported on the installation surface A by the contact of the top edge part of a cord rack 7 and the bent part 2a of the leg part 2 of a supporting member 4, and the side surface of a rear edge plate 13 is press-attached with the edge surface 23a of a brake member 23 by the dead weight of the reel 11. If the cord 14 is pulled out in this state, the inertial revolution of the reel 11 is suppressed, since a brake power acts by the press contact between the side surface of the rear edge plate 13 of the reel 11 and the edge surface 23a of the brake member 23, and the drive-out of the cord 14 over necessity is prevented.

Title: Signal processing circuit of magnetic detection type rotary angle detecting sensor
Inventor: FUJIMOTO MASAHIKO
IPC: G01D5/245
Filed: 1984-04-28
Abstract: PURPOSE:To prevent the output loss at the time of high speed rotation and to prevent erroneous operation due to noise at the time of low speed rotation, by reducing an attenuation time constant at the time of high speed rotation and enhancing threshold voltage at the time of low speed rotation. CONSTITUTION:The analogue input A from a magnetic detection type rotary angle (MPU) sensor is compared with threshold voltage VTH2 by a comparator 4 and digital data D is outputted. In a peak hold circuit 5, the peak value VPK of the analogue input A is held by capacitor C to output voltage VTH1. A variable gain amplifier 6 converts voltage VTH1 to VTH2 and the gain adjusting resistor VR thereof is electronically controlled by a frequency/voltage (F/V) converter circuit 7 which in turn converts the repeated frequency (proportional to the number F of rotations) of the output D of the comparator 4 to adjust the gain of the variable gain amplifier 6. By this method, the output loss at the time of high speed rotation is prevented and erroneous operation due to noise at the time of low speed rotation is prevented and this sensor is suitable for an engine.
