Title: Amplifier circuit with signal erasure function
Inventor: SATO HITOSHI
IPC: H03F1/00
Filed: 1990-05-25
Abstract: PURPOSE:To reduce the cost and to prevent the occurrence of an undesired voice signal or the disturbance on a video image by providing a signal erasing function preventing noise from being caused to an output signal arising from power ON/OFF or channel changeover. CONSTITUTION:With a voice erasing function set (Mute ON), since a transistor (TR) (Q1) as an electronic switch is turned on, a point (B) connects to ground in terms of AC component, and an AC component (voice signal) current (i1) flows to a ground point via the TR Q1 and a DC interrupt capacitor (C2). Thus, the AC component (voice signal) is not outputted to a point (C) and the voice signal is muted. On the other hand, with the voice erasing function reset (Mute OFF), since points (B) and (E) are equi-potential, even when the TR (Q1) is turned on (transit from OFF to ON), a DC level at the point (B) is not fluctuated.

Title: Power circuit
Inventor: NISHITANI TADATSUGU
IPC: G02F1/133
Filed: 1994-06-17
Abstract: PURPOSE:To provide the power circuit which is always constant in voltage and neither charged nor discharged by providing an auxiliary power source which outputs a voltage level having a nearly constant potential difference from the voltage level of the output of a power source. CONSTITUTION:A gradational power circuit consists of a gradational voltage generating circuit 1, an auxiliary voltage generating circuit 2, and a capacitor 3. The output of the gradational voltage generating circuit 1 becomes the output of the gradational power circuit to supply a gradational voltage, and is also connected to plus electrode terminal of the capacitor 3. The output of the auxiliary voltage generating circuit 2 is connected to the minus electrode terminal of the capacitor 3. Further, a polarity inversion signal POL is inputted to those gradation voltage generating circuit 1 and auxiliary voltage generating circuit 2. Then when the output of the power source varies in voltage level, the voltage level of the output of the auxiliary power source also varies following it and the voltage applied between the two terminals of the charge storage means becomes nearly constant. Therefore, even if the voltage level varies, the charge storage means is neither charged nor discharged.

Title: Controller
Inventor: KITAMURA FUMIHIDE
IPC: G06F9/22
Filed: 1988-06-01
Abstract: PURPOSE:To eliminate the overhead caused by an address decoding action by activating directly the address of a microprogram to be executed next without decoding the address. CONSTITUTION:When a microprogram is sequentially carried out, the reading action of a new instruction is inhibited by a control signal 12. At the same time, the output of a decoder 8 is inhibited by a control signal 17. Instead a product member line 9n of an address (n+1) is directly activated from the output of a latch 20 by control signal 16. Then a product member line (9n+1) of a ROM 6 storing the program of an address to be executed next is directly activated according to the contents of the latch 20. Thus it is not required to decode the address and therefore the overhead due to a decoding action is never caused. In addition, the production is not required either for the next address of the program.

Title: Active terminator
Inventor: TAKIZAWA NOBORU
IPC: G01R31/30
Filed: 1994-06-17
Abstract: PURPOSE:To easily recognize operation at high-temperature time by storing the state of an operation stop by a thermal shutdown means if detected temperature reaches specific high temperature. CONSTITUTION:The output of the thermal shutdown circuit 10 is supplied to an RS latch circuit 12. This RS latch circuit 12 receives the output of the thermal shutdown circuit 10 and stores its variation. Namely, when the thermal shutdown circuit 10 detects the active terminator being at high temperature sets a value (e.g. '1') indicating that in the RS latch circuit 12. The output of this RS latch circuit 12 is led to a THD terminal 16 through a buffer amplifier 14. For the purpose, it can be decided whether or not the active terminator is in a thermal shutdown state by checking the state of the THD terminal 16. A communication error can, therefore, be prevented by recognizing the operations top and lowering a data transmission speed.

Abstract: PURPOSE:To prevent warpage and twist after forming and to improve the accuracy of flatness, shape and size of a metal gasket by clamping the outside circumferential part of a blank, forming a prescribed rib and performing blanking while exerting tension on the inside of the blank to the yield point of the material. CONSTITUTION:When a plate holding ring 1 is risen under pressure P01, the small projection 1a of the ring 1 fits into the recess 2a of a ring receiver 2 and clamps the outside circumferential part of a blank 3. When the ring 1 is risen under the pressure P01, the bottom end of a stationary pad 4 fits onto the step 1b of the ring 1 and at the same time the trapezoidal projection 6a of a block 6 ascending under the pressure P01 fits into the recess 8a of the block 8. The blank 3 is pulled by the outside circumferential part and the middle part, by which the tension in the yield point region of the material is exerted thereon. The formation of a prescribed rib in this state is accomplished by rising a punch 5 under pressure PM. The punch 5 is further risen under pressure PM to blank the outside circumference and middle of the blank 3, by which a metal gasket 9 is formed.
