Title: Semiconductor light-receiving device
Inventor: SUZUKI HIDEAKI
IPC: H01L27/146
Filed: 1981-03-10
Abstract: PURPOSE:To decrease the degree of sensitivity of an unnecessary sensitive section as well as to sharply reduce the crosstalk for the subject device by a method wherein a P-N junction region is formed at a part of the unnecessary sensitive section, and the P-N junction section is short-circuited or invertedly biased. CONSTITUTION:A P type regsion 10 is formed on the wafer having an N type epitaxial layer 9 grown on an N<+> substrate crystal. Then, light receiving sections 11 and 12 with two independent P-N junctions. Subsequently, electrodes 13-15 are formed. At this time, the electrode 15 is electrically connected to the region 10, and at the same time, it is connected to the layer 9. As a result, the P-N junction consisting of the region 10 and the layer 9 is self-short circuited. Accordingly, as the greater part of the carrier which generates unnecessary sensitivity and crosstalk is absorbed and discharged by the region 10, the generation of an unnecessary signal can be suppressed completely in a highly excellent light-receiving sensitive condition. Besides, the junction section of the region 10 and the layer 9 may be invertedly biased without performing short-circuiting on it.

IPC: F24F11/02
Filed: 1986-02-18
Abstract: PURPOSE:To improve the comfortable property of a living space employing an air- conditioning machine, upon starting the cooling operation thereof by a method wherein the blow-off air of the machine is concentrated downward, a compressor is driven in a high speed and the amount of ventilation is increased upon starting the cooling operation thereof. CONSTITUTION:The title air-conditioning machine drives an airflow deflecting vane 1 downward, the airflow deflecting vane 5a rightward and the airflow deflecting vane 5b leftward upon starting the cooling operation thereof. In this case, the blow-off air of the machine is concentrated downward to obtain room cooling effect without providing a human body with hot feeling immediately after starting the cooling operation. According to this method, uncomfortable feeling due to a temperature difference generated between a ceiling and a floor may be eliminated. In this case, a compressor and a fan motor are driven at high speed. When a room temperature has arrived at a set temperature, the compressor and fan motor are driven in low speed and the deflecting vanes 1, 5a, 5b are turned oppositely and stopped. In this case, the blow-off air is distributed horizontally to cool the whole of living space uniformly from the circumference of the same space whereby uniformized and mild cooling may be effected.

Inventor: NAKAJIMA MASAOMI
IPC: G06K9/34
Filed: 1993-02-24
Abstract: PURPOSE:To estimate a character position in a freely hand-written character string with high accuracy by using a synthetic variable found by applying weight to plural graphic features, and deciding the character position quantitatively. CONSTITUTION:A synthetic variable calculation circuit 11 calculates the synthetic variable by using feature quantity calculated by a calculation circuit 10 for circumscribing square unification decision, the weight of a linear discrimination function estimated in advance, and a constant term. A character position estimation processing circuit 12 calculates the minimum character position and the maximum character position at every circumscribing square based on the synthetic variable calculated at the synthetic variable calculation circuit 11. In such a case, the synthetic variable is classified to an area ought to unify a target square with an adjacent square clearly, the one to be separated from the adjacent area clearly, and the one where it is ambiguous to be unified or separated. The character position can be decided by deciding whether or not the estimate of the character position should be increased for each area.

Abstract: PURPOSE:To simplify the discrimination of the permitted number of pipes to be loaded such as steel pipes loaded on a ship by equipping a discrimination means comparing the distance between the center of a pipe and the inwall of a ship's hold with the radius of the pipe and finding the coordination data indicating the shape of the inwall of the ship's by an input device. CONSTITUTION:Coordination data for the inwall of a ship's hold and data for pipe diameter are inputted from an input device and stored in a data part 5. Horizontal and vertical counters in a processing part 3 are reset. Then a distance (d) and a radius (r) are squared respectively and d<2> and r<2> are compared. If d<2>>r<2>, the said horizontal counter is added (plus 1) and, in case of d<2r<2>, the vertical counter is added (plus 1). Whether the number of loaded pipes reaches a fixed upper limit or not is checked by the top of the inwall and, when the number is less than the upper limit, the said calculation and discrimination are continued. The permitted number of pipes to be loaded is displayed by outputting the obtaind calculation value (by the horizontal and vertical counters) through an output device 7.

Abstract: PURPOSE:To enable reduction of a projection which is generated in a wiring because of distortion of the remaining wiring due to thermal stress, etc., by making a partial region of a layer insulating film on a first wiring whereon a second wiring is not formed thinner than an insulating film excepting the partial region. CONSTITUTION:A partial region of a layer insulating film 12 on a first wiring 11 whereon a second wiring 13 is not formed is made thinner than an insulating film excepting the partial region. That is, a PSG film (interlayer insulating film) 12 is made thinner in a part B on the first wiring 11. Therefore, when distortion is generated in the connection wiring 11 because of a stress which is produced in the first wiring 11 itself or a stress of insulating films 10, 13 in a periphery after formation of the PSG film 12, most of the distortion of the connection wiring 1 in the part is freed. Accordingly, remaining distortion excepting the part is reduced, thereby restraining generation of projection in the connecting wiring 11.

Title: Seat belt device for automobile
Inventor: OTA KATSUHISA
IPC: B60R22/12
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent an occupant from being given an oppressive feeling without enlarging the retracting force of a retractor by providing a stitch crossing a webbing on the part passing the through ring of the webbing. SOLUTION: When an occupant sits on a set 6 and engages a tongue plate 4 with a buckle 5, a webbing 2 is delivered from a retractor 1 and passes a through ring 3. A foreign matter adhered there is removed by rubbing the periphery surface of downside of the webbing insertion hole of the through ring 3 by a stitch 7. In other words, as the foreign matter on the through ring 3 is removed at every time of the mounting of a seat belt, the foreign matter is scarcely adhered on the through ring 3 and it is not feared that the slide resistance of the webbing 2 becomes big. Therefore, it does not need to enlarge the retracting force of the retractor 1 and give an oppressive feeling to an occupant.

Abstract: PURPOSE:To correct drift even during measurement with high precision by utilizing a signal having temperature dependency outputted from a semiconductor strain gauge itself. CONSTITUTION:When the inphase components of earth voltages Vc and Vd developed at a couple of ouput terminals C and D of a bridge circuit 10 vary in  level with the temperature of semiconductor strain gauge elements R1-R4 while meausrement signals appearing at the terminals C and D have the same level, a signal V0' ouptutted between operational amplifiers OP1 and OP2 varies in level.
