Title: Carrier wave reproducing device
Inventor: SUGIYAMA FUMIO
IPC: H04L27/227
Filed: 1978-06-30
Abstract: PURPOSE:To always ensure the steady reproduction of the carrier wave by preventing the shift of the stability point of the loop in the period of a small carrier-noise ratio C/N, and thus to reduce the bit error rate of the demodulation data in the coherent detection. CONSTITUTION:With application of digital phase modulation signal PSK wave (a), AM detection circuit 19 detects the envelope curve of the PSK wave. And gate control circuit 12 delivers control signal (b). This control signal features the L level while the envelope curve keeps the low level, i.e., the C/N corresponding to the narrow part of the PSK wave. Gate circuit 13a and 13b are closed regardless of the state of digital phase frequency comparator circuit PFC11, and charge pump circuit 14 receives the OFF control. Thus, the fluctuation like (c) of PFC11 occurring for that period can be prevented via circuit 13a and 13b, and the output of LPF15 under the steady state is given to voltage control type oscillator VCO16 like (d) after stabilization.

Title: Developer detector
Inventor: TAKAHASHI YUJI
IPC: G03G15/08
Filed: 1990-03-28
Abstract: PURPOSE:To allow the stable and sure detection of the remaining amt. of a developer by providing a means for setting the conditions for announcing the replenishment of the developer again after the announcing of the developer replenishment is executed. CONSTITUTION:A detecting sensor 101 oscillates at a certain frequency when the developer sticks to an oscillation surface. The sensor generates an output voltage of a specified level when the developer is not stuck to the oscillation surface. The digital signal corresponding to the output conditions of the sensor is outputted from a sensor interface circuit 102 and is taken into a CPU 104. The CPU 104 decides the content of a digital value and decides 'developer absent' if the value is below a specified value. The CPU stores this information into an EEPROM 105. The announcement to change the conditions set heretofore to the 'developer replenished' after the 'developer absent' state to the conditions different from the 'developer absent', i.e. the request for replenishing the developer, is executed for 0.3 second each and 3 times the number of continuous detection. The remaining amt. of the developer is stably and surely executed in this way.

Abstract: PURPOSE:To prevent the corrosion and change of properties of a wiring metal by removing an insulating film or a metallic thin-film applied onto a semiconductor substrate through reactive ion etching and conducting the high-frequency sputtering etching of an inert gas without exposure into atmospheric air. CONSTITUTION:A photoresist 14 is formed to a wiring section on the laminate of an silicon substrate 11, an silicon oxide film 12 and an aluminum film 13. When the film 13 is removed selectively through a reactive ion etching RIE method, using the resist 14 as a mask, a reaction product 16 adheres onto a side face. The substrate 11 is not exposed to atmospheric air, transferred into a sputtering etching chamber separate from a reaction chamber in which RIE is performed, and etched through the high-frequency sputtering of an inert gas in environment in which an PIE gas and the reaction product are not mixed. Consequently, the product 16 adhering on a section to be etched is gotten rid of. Accordingly, the corrosion and change of properties of an aluminum wiring can be obviated.

Filed: 1992-04-02
Abstract: PURPOSE:To make a disk device thin structive and to enhance the reliability by enabling a chucking lever to turn by a prescribed angle in a plane direction of a rotary plate by a spring property. CONSTITUTION:Centering is performed with a spindle 120 by engaging with a center hole 2a of a disk hub 2 made of a metal bonded to the center of the disk housed in a jacket. Then, a driving pin 121e provided on one end of the chucking lever 121 is engaged with a driving hole 2b in an approximately quadrangular shape provided in an eccentric position from the rotary plate fixed to the spindle 120 and the center of the hub 2. Then, the other end of the lever 121 is fixed by the spring property to the rotary plate, so that the lever 121 is capable of turning in the plane direction of the rotary plate by the prescribed angle. Consequently, a moving amt. of the pin 121e in the axial direction is almost eliminated, allowing only the plane direction to move, so that a space in the thicknesswise direction of a motor can be secured. Therefore, the number of parts is reduced, and enhancement of the reliability and thin formation and miniaturization of the motor can be achieved.
