Title: Load cell scale
Inventor: NISHIYAMA YOSHIHISA
IPC: G01G3/142
Filed: 1989-11-30
Abstract: PURPOSE:To attain a high-accuracy measurement by providing a computing element which increases the resolution of A/D converters by N<1/2> times or above when the number of the A/D converters is N and divides the sum of their digital outputs by the multiple. CONSTITUTION:The outputs of respective load cells 2a - 2d are amplified by operational amplifiers 11a - 11d and A/D-converted 12a - 12d. The results are added 14, the sum is divided by the resolution through a divider 15, and the load value is stored 16. Further, the cells 2a - 2d which are A/D-converted 12a - 12d are put in relation between the load and digital outputs based upon the load. Further, the quantization error of the A/D converters is constant regardless of whether the resolution is large or small, so when the number of the A/D converters in use is N, the error of the load generated by the addition becomes N<1/2> times by a variance adding method, so the digital outputs are added while the resolution of the individual A/D converters is set >=N<1/2> times as large as necessary irreducible resolution. The value after the addition is equalized to the sum of values divided by the multiple of the resolution and the quantization error can be improved to the value where one A/D converter is used.

Title: Stroboscopic device
Inventor: TANAKA KAZUO
IPC: H05B41/32
Filed: 1991-11-27
Abstract: PURPOSE:To ensure a stroboscopic device to emit light by applying the charging voltage of a voltage multiplying capacitor superposed on the charging voltage of a main capacitor, across the main electrodes of a flash discharge lamp, when an insulation gate type bipolar transistor IGBT is turned on. CONSTITUTION:Even when a flash discharge lamp 5 is in ionized state, and the cathode potential thereof is low, a voltage multiplying capacitor 17 and a trigger capacitor 33 are so charged that the terminals thereof connected to the cathode of the lamp 5 have high potential. As a result, charging operation progresses without any trouble, from the time when the lamp 5 is ionized. In other words, the charging operation starts concurrently with the power interruption of IGBT. Thus, even when the supply of a light emission signal to a drive control circuit 13 is interrupted, and a light emission start signal is supplied to a silicon controlled rectifier SCR 18 in a very short time for performing repeated light emitting operation, the capacitor 17 is already charged at the start of the deenergizing operation of the IGBT. Charging voltage or the like, therefore, can be applied to the capacitor 17, when the SCR 18 is turned on, and the discontinuity of light emission from the lamp 5 can be prevented.

Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To facilitate wiring and execution by arranging ultrasonic sensor units facing in the direction of the entering and leaving of a vehicle at a boundary in the direction of the depth of the parking space. SOLUTION: The ultrasonic sensor units 2A to 2N are arranged facing in the direction of the entering and leaving of vehicles 34 and 35 at the boundary 36 in the direction of the depth of the parking space 30. As the vehicles 34 and 35 are detected by ultrasonic through the use of the ultrasonic sensor units 2A to 2N, the detecting sensitivity of the vehicles 34 and 35 are not affected by the color of the vehicle, the shape of a bumper grill and the weather. In addition, as the ultrasonic sensor units 2A to 2N are horizontally arranged at the boundary 36 of the parking space.  In the case of installing a management device for the number of vehicles in an existing parking area, without spraying, in the case of near one, the ultrasonic sensor units 2A to 2N are easily installed not only to a new parking space but also to an old parking space and wiring needs only crawling on a floor near the boundary 36 in the direction of the depth of the parking space 30.

Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To obtain the adjusting technique of the corner conduction in a field effect transistor having no connection with a channel conduction by a method wherein a gate oxide, extending along a part of the side face of a conductive channel, and a part of a gate electrode are provided on the boundary surface of a conductive channel and a trench structure. SOLUTION: A transistor has a conductive channel 10' having a relatively wide width, in the substrate 10 located between each shallow type trench isolation structure 12 and under a gate oxide 14 and a gate electrode 16. When the gate electrode voltage Vt, which is sufficient to turn off the main channel conduction, is applied to the gate electrode 16, the electric field in the conductive channel 10' is made uniform as an equipotential line 18. Corner conduction can be made possible on a part of a narrow width channel where the cross section of the conductive channel is relatively made larger. Accordingly, the degree of contribution of the corner conduction to transistor conduction becomes relatively larger, or on the contrary, larger Vt is required.

Title: Method for separating and removing water from hydrous soil
Inventor: HATANO HITOSHI
IPC: C02F11/12
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To perform optional dewatering widely in a short period by releasing gas such as compressed air heated in hydrous soil and pressure steam or liquid/ fluid into soil. SOLUTION: Compressed air 5 is released from an ejection opening 7 into a soft mud layer 1 containing water through an air sending pipe 6. The air 5 expands in the opening 7 and generates weak vibration in the layer 1 when it makes surrounding earth explode, and makes heated air generate a temperature difference between it and water in earth. In this way, a temperature transfer by convection is generated in the layer 1, water in the layer 1 is facilitated to evaporate and to ascend, cracking from a lower part in earth which can not be obtained by surface drying is made to occur so that evaporation drying over a wide range is made possible together with natural surface drying. In this way, the implementation of large scale dewatering in a reclamation- development site and others is made easy, and optional dewatering can be preformed for a short period.

Abstract: PURPOSE:To make the diameter of a coated optical fiber small without lowering transmission characteristic and mechanical strength by setting the Young's modulus and the thickness of a secondry coat equal to or above a specified value and setting the Young's modulus of a primary coat equal to or under a specified value and the thickness thereof equal to or above a specified value so that the diameter of the coated optical fiber may be equal to or under a specified value. CONSTITUTION:The coated optical fiber 1 is constituted by providing the primary coat 3 on a bare optical fiber 2 whose diameter is 125mum and further providing the secondary coat 4 on the coat 3, and the outside diameter of the coat 4 is set at <=210mum. The Young's modulus and the thickness of the secondary coat 4 are set at >=40kg/mm<2> and >=20mum, respectively. Then, the Young's modulus and the thickness of the primary coat 3 are set at <=1kg/mm<2> and >=10mum, respectively. Thus, the diameter of the coated optical fiber is made small without changing an in-use optical communication system. The sufficient mechanical strength of the coated optical fiber is obtained and the coat is not damaged at the time of producing or handling. When a temperature is low, the contracting stress of the primary coat in a longitudinal direction directly acts on the bare optical fiber, so that a failure that the microbend occurs in the coated optical fiber is prevented and the diameter of the coated optical fiber is made small.
