Title: Multicolor thermal recording material
Inventor: WASHISU SHINTARO
IPC: B41M5/28
Filed: 1987-01-09
Abstract: PURPOSE:To obtain a multicolor thermal recording material not requiring excessive performance of a thermal head, by providing at least one color forming unit layer on each side of a transparent base while making the unit layers be substantially transparent and be capable of forming colors with different hues. CONSTITUTION:A thermal color forming layer 4 is provided on one side of a transparent base 3 by coating, a thermal color forming layer 1 is provided on the back side of the base 3, and an electrically energized color forming layer 2 is provided thereon. The order of providing the layer 1 and the layer 2 may be arbitrarily set. The color forming layer 2 is conductive, and is capable of forming a color when Joule heat is generated by passing an electric current therein. Each of the thermal color forming layers 1, 4 is capable of forming a color under thermal energy supplied directly thereto from the surface thereof. For independent color development of the color forming layers, a system of a coupling color forming reaction of a diazo compound and a photo-fixation reaction is adopted. After the first thermal recording with lower thermal energy, photo-fixation is conducted by use of a light source emitting rays of a specified wavelength for selectively photolyzing only the diazo compound in the color forming layer. Then, a higher-temperature color forming layer disposed on the inner side and having a lower thermal sensitivity is subjected to thermal recording with thermal energy relatively lower than that used for the first thermal recording, whereby the colors can be independently developed on the base.

Title: Acrylic rubber composition
Inventor: FURUSAWA RYUICHI
IPC: C08L33/04
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To obtain an acrylic rubber composition whose vulcanized product is hard to stick fast to metals and does not cause corrosion or discoloration of metals by adding MgO in a specified amount range to a chlorine-containing acrylic rubber. SOLUTION: Into 100 pts.wt. chlorine-containing acrylic rubber is incorporated 0.01 to 10 pts.wt. MgO to obtain an acrylic rubber composition. Conventionally, chlorine-containing acrylic rubbers are vulcanized and molded to be used for a variety of sealing applications. They are accompanied by a problem that chlorine atoms contained in the polymer are separated from the polymer in the crosslinking reaction to cause the partner metal to be corroded or to be stuck to the rubber. Further, when they are used for sliding members, there arises a problem that the resistance is increased and the slidability is lowered. The present acrylic rubber composition containing MgO in a specified amount range is hard to stick fast to metals and does not cause corrosion or discoloration of metals.

Title: Oxide cathode
Inventor: SUMI KOICHIRO
IPC: H01J1/14
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To provide an oxide cathode capable of increasing the donor density and extending the service life for emission. SOLUTION: A cup 2 is formed like a cap, and a base metallic wire 1 made of a fine linear base metal is irregularly bent and housed in the whole of space made of the recessed upper side of the cup 2. A gap between each section of the base metallic wire 1 is filled with particles of carbonate 3 in a dispersed state. As a result, a contact area between the base metallic wire 1 and the carbonate 3 increases, and the volume of free barium generated due to reaction between a reducer contained in the base metallic wire 1 and the carbonate 3 increases as well. Consequently, high current density can be obtained. Also, as the high current density is obtained, the electric resistance of an intermediate later resulting from reaction between the reducer and the carbonate 3 becomes low. According to this construction, sintering can be prevented and a service life for emission can be extended.

Title: Main shaft stand for measurement device

IPC: B23Q17/20
Filed: 1980-01-18
Abstract: PURPOSE:To automatically carry out operation, keep a tightening force on a tapered shank always at constant value and improve measurement precision by driving a draw bar hydraulically and fixing the tapered shank. CONSTITUTION:If a pedal for a change-over valve is stepped on, a pressure is introduced into a pressure chamber A of a drawing device, causing a draw bar to move backward. Because of the relative backward movement of a cylindrical holder 28 toward a guide sleeve 29, a steel ball 27 for a holder 28 is squeezed into the inner side of a radius direction by means of an internal circumferential surface 29a on the small diameter side of a guide sleeve 29, and is fitted to a tapered neck part 3b of a pull stud bolt 3. As a result, a tapered shank 1 is pulled backward through the intermediary of the pull stud bolt 3, and is fixed on the front side end surface of a spindle 17 through a gauge adaper 2. At that time, workability is improved and prearranged tightening force is maintained on account of automatic draw bar 24 drive through the intermediary of a pressure fluid controlled at a prearranged pressure.

Title: Automatic switching device of vehicle temporarily usable as four-wheeled vehicle
Inventor: OOKAMI MASAAKI
IPC: B60K23/08
Filed: 1982-01-13
Abstract: PURPOSE:To avoid previously the occurrence of slip by following method in which the occurrence of slip is estimated by catching the abnormal elevation of engine-revolution number in running state, thereby switching over the device automatically to four wheel-drive. CONSTITUTION:Pulse width is read by the signal from the sensor 18 for engine- revolution, and the first detection for engine revolution number carried out is stored in a resistor 23-A. Next, the second detection is stored in a resistor 23-B. Then, the subtraction between the detected value PA and PB is achieved. When the second pulse-width PB becomes remarkably small, and the engine-revolution number is elevated abnormally, the slip is judged to occur probably and said result is stored in a resister 23-D. The existence of the position of speed changing has been stored in a resister 23-C by the signal from a neutral switch 19 by way of a circuit 30. If the slip is estimated to occur probably, a solenoid valve 16 is switched over to four-wheeled drive.
