Patent JP-H02166308-A (JP)
Title: Combustion device
Inventor: YOSHIDA YUTAKA
IPC: F23N1/02
Filed: 1988-12-19
Abstract: PURPOSE:To always keep an aif-fuel ratio at a specified value and to maintain a complete combustion state by providing a detecting part to detect the number of revolutions of a fan for feeding hot air run by means of specified torque and a combustion control part to control the number of revolutions of a blower for combustion or the drive frequency of a pump according to the detected number of revolutions. CONSTITUTION:Based on a signals from a temperature set part 14 and a room temperature detecting part 15, commands S1 and S2 for high, medium and low are outputted to a combustion control part. Feedback is applied on a blower 4 for combustion by means of a number of revolutions detecting part 13A so that the number of revolutions equal to a value demanded by the command S1 from a combustion control part 12 is provided. The command S2 is outputted to a propeller fan 10 from the combustion control part 12 so that the rotation, e.g. high, medium, low is effected at constantly identical torque. The number of revolutions detected by a number of revolutions detecting part 13B is always reported to a deciding part 16. The deciding part 16 compares a signal S3 from the number of revolutions detecting part 13B with a signal S1 from the combustion control part 12 to output a correction command S4 to the combustion control part 12.

Title: Light dimming device
Inventor: ICHIKAWA TETSUO
IPC: F21S2/00
Filed: 1994-11-30
Abstract: PURPOSE: To easily make selective adjustment for the various states of illumination light with respect to an object by independently and electrically adjusting the light reflection factor or the light transparency of plural light dimming division surfaces compressing light dimming liquid crystal sheets. CONSTITUTION: Light from an illumination light source 2 is reflected by a light dimming plate 4 to irradiate an object 6 and the illumination light is adjusted by the light dimming plate 4. In this light dimming device, the light dimming plate 4 comprising an umbrella type reflecting plate is divided into a plurality of light dimming division surfaces A to H and respective light dimming liquid crystal sheets are stretchingly provided. The liquid crystal sheets are constituted by holding a resin layer in which a liquid crystal is dispersed between transparent conductive films and further covering it with a polyester film. Electrodes are provided in the transparent conductive films and a voltage is applied between the electrodes to control the arrangement of a liquid crystal molecule to change the transparency of the liquid crystal sheets.  The control is performed through a light dimming controller 8, thereby changing the reflection factor of the respective light dimming division surfaces A to H to adjust illumination light with respect to the object 6.

Title: Manufacture of wet multilayer ceramic circuit board
Inventor: WATABE TAKAYOSHI
IPC: H05K3/46
Filed: 1987-12-21
Abstract: PURPOSE:To eliminate a need for using gold and to enhance the reliability of a soldering operation by a method wherein the surface of a refractory metal conductor such as tungsten, molybdenum or the like is plated with nickel and substituted copper and is covered with a flux. CONSTITUTION:After a nickel plating operation by a conventional process, a carbon resistance 4 is printed on a circuit board where one part of a nickel plated film 3 has been removed; it is sintered; an overcoat 5 is printed on its surface. A copper plated film 6 is formed on the nickel surface not containing the overcoat by using a substituted copper plating liquid composed of copper sulfate: 0g/l, sulfuric acid: 25 ml and a polyxyethylene compound (e.g., containing a small amount of polyethylene glycol and stearyl amine in 1l). An imidazole-based flux 7 of an oxidation-preventive film is formed on the surface plated with substituted copper. The copper plated film forms an oxide film in the same manner as nickel; however, because it is the oxide film which can be removed by a soldering flux, it is possible to obtain a sufficient soldering characteristic without a gold-plating operation.

Title: Conductive film for printed circuit board and manufacture thereof
Inventor: ISONO MASAAKI
IPC: H05K1/09
Filed: 1988-12-20
Abstract: PURPOSE:To obtain a conductive film of high migration resistance by forming the film with three layers of electrolytically deposited copper, zinc and copper, and diffusing zinc in the copper layer. CONSTITUTION:The plating of copper, zinc and again copper applies in sequence, thereby forming the first, second and third layers. Each layer after formed is heated and annealed. As a result, the zinc layer is diffused from the second layer to the first and third layers, thereby introducing zinc into copper. Consequently, when a printed circuit board is constituted, zinc in the first and third layers is ionized earlier than copper and is eluted even if a vapor deposits between circuits, thereby restraining the elution of a copper ion. Eluted zinc is not easily deposited and the migration thereof is restrained. According to the aforesaid construction, the migration resistance of the conductive film as a whole is improved and the electrodeposition capability of the copper plated layer is alleviated, thereby improving the flexibility of the film.

Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To make walking easier and prevent a damage to a human body to a minimum even after falling down by utilizing, placing and fixing thinning lumber in a bridge box as a cover for a side-ditch along a road. SOLUTION: A plurality of boards 5 made from thinning lumber orderly arranged, placed in a bridge box 1 and fixed.

Also, hand holds 2 are made at both the ends of the box 1; even though the box 1 is orderly arranged on the side-ditch 6, holes 4 as hand holds are provided for use when removing several units of the bridges 5. Also, handles 2 are attached inside the hole. Thus, the bridge box can be easily removed partially for repairing if required. By doing this, the lightest side-ditch cover can be installed, on which people can walk for many hours and get tired little.  Partial repair can be performed easily even after the final arrangement and fixation.

Title: Method for detecting current for both ac and dc
Inventor: KATSUYAMA TERUSHI
IPC: G01R19/00
Filed: 1989-12-12
Abstract: PURPOSE:To make it possible to detect a current for both AC and DC over a broad range from small current to large current by exciting an iron core to a point larger than coercive force with high frequency, and detecting the change in high-frequency exciting current due to the magnetic field generated with a cuttent to be detected. CONSTITUTION:A high-frequency exciting coil 7 is wound around an iron core 1a characterized by excellent rectangurality of magnetic hysteresis and small coercive force. A detecting resistor 8 whose resistance is lower than the reactance of the iron core 1a and the coil 7 is connected to the coil in series. The coil is excited to a point where a magnetic field is stronger than the coercive force by using a high-frequency power supply. When the small magnetic field which is generated with a current to be detected flowing through a conductor 2a that is inserted into the central hole of the iron core 1a is applied under this state, the exciting range on the hysteresis curve of the iron core 1a is moved. Then, the value in the vicinity of the coercive force of the high-frequency exciting current and the maximum value are changed. The change in current is detected as the voltage drop in the resistor 8 or the change in voltage across the coil 7. The current in AC or DC is detected based on the difference in positive and negative absolute values of these values. The instantaneous large current can be detected based on the sum of the absolute values.
