Title: Tape recorder
Inventor: ASAMI ETSUJI
IPC: G11B15/02
Filed: 1979-05-18
Abstract: PURPOSE: To secure the operation of the program searching of a tape by cutting off an electric power supply to a motor by operating a switch controlled by an intermusic detection signal by making use of the position shift of a connecting plate between a slide plate and head substrate.  
     CONSTITUTION: Between slide plate 13 moved forward by fast traversing rod 5 and head substrate 10 moved forward by reproduction rod 4, the backward motion of substrate 10 can be locked at the intermediate position between the stop position and reproduction position when rod 5 in reproduction mode is operated by connecting plate 15. In addition, when rod 5 in reproduction mode is operated, rod 5 maintaining the reproduction mode is released from being locked and the backward motion of substrate 10 is locked with rod 5 locked to maintain fast traverse state for the program searching of a tape. Further, switch 24 controlled by an intermusic detection signal is operated by making use of the position shift of connecting plate 15, thereby cutting off an electric power supplying circuit of motor M.

Abstract: PURPOSE:To produce efficiently sintered parts having high quality by erecting plate-shaped green compact moldings, changing properly the direction thereof, lining up plural pieces in tight contact with each other in the thickness direction and pressing both ends thereof with large-sized heat-resistant plates then sintering the moldings. CONSTITUTION:Plural pieces of the plate-shaped green compact moldings 4 are erected on a tray 7 and are brought into tight contact with the thickness direction. These moldings are lined up while the moldings of which the direction is properly changed are grasped. Both ends of the lined-up moldings 4 are grasped and fixed by retaining materials 6 via the heat-resistant plates 5 consisting of ceramics, etc. at the size to cover both ends. The moldings 4 on the tray 7 are put into a furnace and are sintered. The sticking of the moldings 4 to each other is thus prevented without the generation of camber to the moldings 4 at both ends and the sintered parts having high quality are obtd. with high productivity without receiving the limitation of the height in the furnace port.

Title: Automatic gain control circuit
Inventor: AKAGIRI KENZOU
IPC: H03G3/30
Filed: 1980-05-13
Abstract: PURPOSE:To enable automatic gain control depending on the input level of an audio signal, by changing the time constant of a time constant circuit depending whether or not the gain control by a variable gain amplifier is made. CONSTITUTION:A variable gain amplifier 3 is inserted and connected between an input terminal 1 and an output terminal 2. A control circuit 5 controls the gain of the amplifier 3 based on the input/output of the amplifier 3 or a signal of sum and difference of the input and output. When the output level from a time constant circuit 23 is a reference voltage or more, a transistor Tr17 is off by the output from a comparison circuit 27 and the time constant of a time constant circuit 13 is longer. Further, when the output level from the circuit 23 is less than the reference voltage, the gain control for level compression or the like is not made, and the time constant of the circuit 13 can be short only by a capacitor 16 and a resistor 14 with a Tr17 on. Thus, the gain can be changed automatically depending on the input level of an audio signal, allowing to compress and expand the signal level.
