Title: Knockout device for metallic mold
Inventor: TAKEDA KUNIO
IPC: B22D17/22
Filed: 1985-08-31
Abstract: PURPOSE:To divide a restraint to a work into a base part and a head part, and to execute easily the knockout by separating a projecting part of a part of a lower die forming surface into a base part and a head part, inserting a knockout pin through the base part, and attaching the head part to the tip. CONSTITUTION:After a forming work or a casting work has been executed, when a knockout pin 11 is pushed up together with a head part 9, a work A is brought to knockout. In this case, a projecting part for forming a part of a forming surface of a lower die is fitted into a recessed part of the work A, but since the projecting part 7 is divided into a base part 8 and the head part 9, a force required for separating the work A from the projecting part 7 is reduced by the quantity corresponding to height l' of the head part 9, it can be separated easily from the lower die. Also, since the work 7 is coupled with only the head part 9, it can be separated by a small external force.

Title: Magnetic recorder and reproducing device
Inventor: KOJIMA SUSUMU
IPC: G11B15/087
Filed: 1984-09-17
Abstract: PURPOSE:To perform program searching even when high-speed reproduction is made, by adopting a sound recording and reproducing system using FM modulation and temporarily omitting the carrier of FM modulation recording of sounds, and then, detecting the envelope. CONSTITUTION:A sound signal 20 is inputted into an FM modulator 21 where it is FM-modulated and recorded on a tape 7 through a recording amplifier 22 and head 15 which is exclusively used for sounds. When a program searching signal is recorded on the tape, a switching circuit 24 is turned on and the output of the recording amplifier 22 is shortcircuited, so that no FM carrier can be recorded on the tape 7. Accordigly, a signal of a waveform A is recorded on the tape 7 and a signal omitting period T becomes a program searching signal. At the time of high-speed reproduction, an omitted part of reproduced signals occurs in the reproduced output of the FM carrier. Since a reproduction designating signal 30 has no high-level signal section, the signal omitted part produced at the time of high-speed reproduction can be distinguished from the program searching signal.
