IPC: H04N5/335
Filed: 1981-04-30
Abstract: PURPOSE:To increase the degree of horizontal integration of a picture by successively providng two outputs registers each having bits a half as many as transfer channels. CONSTITUTION:A solid-state image pickup element consists of a photodetection part 1 for obtaining a charge pattern which corresponds to an image pickup pattern, a storage part where the charge pattern from the photodetection part 1 is stored temporarily, and an output part 3 of CCD constitution which outputs signals from the storage part 2 successively.

Title: Receiving device
Inventor: OKAMURA CHIYUUJI
IPC: H04B3/46
Filed: 1981-04-30
Abstract: PURPOSE:To eliminate a malfunction caused by a commercial frequency current and to search well a fault of high resistance even in a section where the commercial frequency current flows, by setting a filter to eliminate the commercial frequency to a fault point orientating pulse signal receiver. CONSTITUTION:A receiving device 15 can greatly attenuate the commercial frequency component by the function of an active filter consisting of operational amplifiers P1 and P2, resistances R2-R7 plus capacitors C3-C5. Thus an effect of a large commercial current frequency current can be greatly reduced. On the other hand, the pulse current flowed from a high voltage pulse generator when the fault is searched has some fluctuation with its pass output waveform by the effect of the filter 16. However, the DC component has no attenuation with the direct passing properties. As a result, the searching performance is never  lowered for a perfect integral type receiving device.

Title: Burner
Inventor: OGINO TOSHIROU
IPC: F23D3/02
Filed: 1982-04-19
Abstract: PURPOSE:To improve a radiating efficiency through widening of a radiating area and to provide a burner which is beautifull in terms of visual feeling and is easy to operate, by a method wherein a upper cylindrical red-heating tube is located above a secondary combustion part, i.e., a secondary air feed part, and the upper red-heating tube has an opening rate per a unit area being lower than that of a lower cylindrical red-heating tube. CONSTITUTION:With a tip of a wick 1 being ignited, a fuel is gasified by the combustion heat and an air current fed by a natural draft through pores in lower parts of an inner flame tube 2 and an outer flame tube 3, and the gasified fuel is burnt while it is mixed with the air fed through all of the pores in the outer and inner flame tubes 2 and 3 and an opening of a lower red-heating tube 4. The lower red-heating tube 4 is red-heated by the combustion heat produced by combustion in a primary combustion chamber 12 formed with a gap between the lower red-heating tube 4 and the inner flame tube 2, and simultaneously, remaining gas is mixed with air fed through a final secondary air orifices 10 for the perfect combustion. High temperature exhaust gas so produced rises along the upper red-heating tube 8 and is exhausted to the outside through an air orifice 11 and the upper opening of the upper red-heating tube 8.

Title: Electronic watch movement
Inventor: UIRII KURUJITSUKUSU
IPC: G04G21/00
Filed: 1981-04-30
Abstract: An electronic timepiece movement includes a control stem slidably guided in a radial passage of a base plate. Pulling on this control stem brings a return spring acting on the stem into contact with a stud which is carried by the substrate of an electronic circuit module of the movement. This connects a conductive lead to ground, which controls an operation function of the timepiece. The pull-out control stem and associated return spring can be replaced by a push-in member and by a return coil spring located in said passage. The stud is then positioned in a hole of the substrate of the electronic circuit, which hole is situated opposite to the longitudinal axis of the passage. Pressure exerted on this push-in member places a portion thereof into electrical contact with the stud and this connects the lead to ground, as before. Thus, the movement can according to choice be completed for operation either by a push-in control movement or by a pull-out control stem movement.

Title: Infrared ray detector
Inventor: HIKITA SOICHIRO
IPC: H01L27/14
Filed: 1988-03-18
Abstract: PURPOSE:To prevent a crosstalk, to reduce the sheet resistance of an epitaxial layer for forming an element and to increase its S/N ratio, by laminating compound semiconductor crystalline layers having different energy band gaps on an insulating or semi-insulating board, forming a mesa stripe state until the crystalline layer reaches the surface of the substrate, and implanting an element forming impurity into the region. CONSTITUTION:Since elements are isolated until an element forming region 16 of a photodiode 15 arrives at a line-like board, no crosstalk is generated between the photodiodes 15 arranged in a line state. Since an infrared ray having a long wavelength band of 10mum band is transmitted even if the layer 12 of the lower layer is formed to be thick, the sensitivity of the element is not decreased. Since independent bias voltages are applied to crystalline layers 12, 13 for forming the element etched in a mesa stripe state to read the signals of line-like infrared ray detectors in a line address type, the reading speed of the photodiodes is improved to increase the signal storage time, thereby improving its S/N.

Filed: 1978-06-01
Abstract: PURPOSE: To efficiently suck in the dust collected in the depth of the floor by providing a slit-like hole extending from the side front face of a suction port main body to the suction passage in the suction port bottom face.  
     CONSTITUTION: There is provided a slit-like hole 9 communicating a suction port main body 1 with an opening in a warped portion 4 and with the front side of a suction passage. When cleaning is started with the suction port in contact with the floor, airflows flow in from the hole 9 and from the outer peripheral surface of the suction port. The two airflows collide with each other, to form a vortex flow. The dust present in the depth such as near sliding screens and sliding doors is readily sucked into the opening 5 by the function of the vortex flow and the flow penetrating into the depth. In the case of cleaning of a carpet, efficient suction effect is realized.

Title: Automatic printing position correction system of printer
Inventor: SHIRAKAWA MICHIYO
IPC: B41J13/26
Filed: 1990-03-19
Abstract: PURPOSE:To enable a printing position to be automatically corrected by calculation a misalignment between the position of a character printed and a position where the character should actually be located and correcting a transport distance over which a roller transports a medium to eliminate the misalignment. CONSTITUTION:The tip of a test medium 22 is detected by a medium detection sensor 45 and rollers 42, 43 are rotated so that the tip of a medium reaches a position to the left of a printing head 35 position by an initialized logic value X. Thus a logic time by which the tip 21 of the medium can be advanced ahead of the printing head by X is obtained. After printing a test character, the rollers 42, 43 are reversed to detect the half center of the printed test character using a printing position sensor 46. After that, the time spent for the tip 21 of the medium to advance by X is detected using a medium detection sensor 45 at the same time as the detection of the half center, and an actually measured value is stored in memory. Then the difference (d) between the actually measured value x (a distance between the half center of the test character and the tip of the medium) and the logic value x is obtained. Finally a roller 44 is driven by a specified correction value using a motor through a belt.
