Abstract: PURPOSE:To reduce the size of a player cabinet by simplifying control mechanism by stopping a crank, driving a driving plate, at the same position when a slide base having an installed turntable, etc., is at a accommodate or play position. CONSTITUTION:Through the clockwise turning of a rack gear 15, a slide base 9 having an installed turntable 44, etc., moves from a record-disk replacement position to a play position together with a rack 16 and then stops. Then, a driving plate 28 coupling with the gear 15 through a crank 43 and a lead-in latch 29 nip a pin 24 implanted in a pickup plate 23 to rotate a tone arm 5 to a play start position. When the gear 15 further rotates and drives the driving plate 28, the latch 29 is inverted to disengage from the pin 24. Therefore, the crank 43 at this time is at the closest position to a cabinet 1 and the base 9 is therefore considered to be stored in the cabinet 1. Conxequently, the crank 43 is stopped at the same positin in both the side states, simplifying the control mechanism.

Title: Charge transfer device
Inventor: SUZUKI NOBUO
IPC: H01L29/768
Filed: 1982-06-30
Abstract: PURPOSE:To obtain a large voltage gain by utilizing the analog-signal period and the reference-voltage period of an output voltage of a floating junction type charge detecting member, and by changing into a voltage a signal charge proportional to the difference in voltage between the two periods. CONSTITUTION:A capacity C1 between a storage electrode 43 and a substrate 10, the junction capacity C2 of an n<+> layer 45 and the gate capacity C3 of FET51 are determined to be C1>>(C2+C3). An input voltage V0 from a detecting member to a floating gate 43 is an induced noise voltage during the period (TR) between times t1 and t2. Next, it is maintained as a DC bias voltage VB during the period T0 to time t3, and as an analog signal voltage VS during the subsequent period TS. When a pulse phi1 is given to an input source 41 and a pulse phiR to a reset gate 46 during these periods, an excessive charge during the period TR flows out into an n<+> layer 47, and in the subsequent periods T0 and TS, Q1- Q2=C1VS is stored in the layer 45. By this charge, the gate voltage of FET51 is changed by (C1/C2+C3)VS=VS'. Since C1>>(C2+C3), in addition, VS'=VS'', if a gain is 1 approximately, and thus the output VS'' can be obtained by sharply amplifying the detected analog signal VS irrespective of induced noise.

IPC: B22F1/00
Filed: 1978-09-14
Abstract: PURPOSE: To produce the captioned powder of superior performance with grey cast iron machining debris as raw material inexpensively by controlling and roasting the powder having been removed of excess graphite through grinding and separation with a cyclone to the specific oxygen amount in an oxidative atmosphere and subjecting the same to graphitization in a non-oxidative atmosphere.  
     CONSTITUTION: Grey cast iron machining debris is ground by impact action, after which the fine powder particles containing the graphite, etc. having been produced are separated with a cyclone and the powder having been removed of the fine particles is roasted in an oxidative atmosphere to allow oxide films be formed on the surface and control the oxygen amount thereof to 0.5W2.5wt%. Next, the carbon therein is graphitized in a non-oxidative or reducing atmosphere. The roasting reaction considerably stabilizes the later graphitization reaction, thereby yielding the powder for powder metallurgy of superior characteristics. Even more, high economy and stability of performance may be obtained because both processes are readily executed in the continuous integral furnace.
