Title: Automatic if gain control system of time-division multidirectional multiplex communication system
Inventor: OOTOMO DENSUKE
IPC: H04B7/24
Filed: 1979-02-27
Abstract: PURPOSE: To exercise batch gain control over received signals, differing in incoming level, from subordinate stations by inputting input signals to a variable gain amplifier after delaying by a delay unit.  
     CONSTITUTION: By way of constant gain amplifier 6, detector 7 and integrator 8, an input signal is outputted as a gain signal to variable gain amplifier 4. Further, the input signal is delayed by delay unit 5 as long as the signal processing time of amplifier 6, detector 7 and integrator 8. As its input level increases, the output of detector 8 also increases to reduce the gain of amplifier 4. Therefore, batch gain control over received signals differing in incoming level can be exercised by inputting the input signal to variable gain amplifier 4 after delaying by the delay unit, so that automatic gain control can economically be exercised through the simple circuit.

Title: Timekeeper structure having wheel train
Inventor: OMURO MAKOTO
IPC: G04B29/02
Filed: 1991-01-23
Abstract: PURPOSE:To heighten an SN ratio of signal light and conduct a roughness check of a plurality of gears different in height without any adjustment by performing non-reflection treatment on a plate part on which a beam of light shines in regard to timepiece move having a plate and wheel train. CONSTITUTION:Measurement target parts 2-4 for inspecting a plurality of wheel train for each motor are provided in regard to a timepiece having a plurality of motors for timepiece move 1. The edge 5 of a gear is passed and a non- reflection treatment part (for instance, black paint is used) 7 for absorbing and attenuating a beam of light on the surface of a plate 8 on which the beam 6 is emitted. Thereby, because modulated light from a plate part is lost, the difference between it and the other modulated light from the edge 5 of the gear becomes clearer. In order words, since the SN ratio of a signal light is heightened, focusing need not be performed each time even if the measurement parts are changed over and the height of individual gears is a little different. As a result, the time of a roughness check process can be reduced.

Title: Solid-state image pickup device
Inventor: IWASAKI SHUNJI
IPC: H04N5/376
Filed: 1988-02-03
Abstract: PURPOSE:To prevent the error action of a diaphragm device even when an intensive light suddenly hits by sampling and clamping at a timing when no picture element exists at all. CONSTITUTION:A timing pulse is generated at a second timing generation circuit 8 while none of the picture elements such as an optical black and an effective picture element, etc., a picture signal is clamped with the use of this timing pulse at a first clamping circuit 4 and the influence of the intensive light is prevented. The influence of a dark current is prevented by clamping the picture signal of the period of the optical black at a second clamping circuit 7. A diaphragm controller 6 executes the opening/closing action of the diaphragm so that the average image level of the picture signal clamped at the first clamping circuit 4 may equalize with a reference level. Thus, even when the strong light suddenly makes an incidence, the optical diaphragm device does not malfunction and a light quantity can be diaphragmed.

Abstract: PURPOSE:To judge the quantity of clothes, etc., accommodated in a wash trough quickly by furnishing a water supply sensing means to sense the water supply by a water supply means into the wash trough which suits the accommodated clothes, and judging the quantity of the clothes from the sensing result. CONSTITUTION:A water level sensor 17 senses the water level from change in the oscillation frequency resulting from rise of the air pressure in an air trap 12 when water stagnates in a wash trough 4, and the water supplied to the wash trough 4 only splashes first over the clothes and permeates, and does not stagnate, which however takes place after being saturated with the clothes. The time until the supplied water stagnates, i.e., the time until a certain change in the oscillation frequency appears in the water level sensor 17, depends upon the quantity of the clothes, being shorter with smaller quantity and longer with a greater quantity. Therefore, judgement of the quantity is conducted on the way of first run of water supplying. Thus, the quantity of clothes can be judged quickly without awaiting finish of water supply and accordingly the start of the agitation.
