Title: Optical functional membrane
Inventor: WAKUMOTO MASANOBU
IPC: G01N27/12
Filed: 1987-03-26
Abstract: PURPOSE:To form a convenient optical functional membrane, by integrating the membrane having an optical function taking out a necessary wavelength component from a radiation component with a membrane having a gas detecting function. CONSTITUTION:An optical functional membrane is provided to the glass bulb of a halogen lamp 1. This optical functional membrane is formed by a membrane composed of at least one kind of a component selected from a metal, metal oxide, metal fluoride and metal sulfide, for example, a membrane having an optical function obtained by the vacuum vapor deposition of TiO2 or SiO2 and providing a gas detection layer detecting O2, CO and H2 thereon. Only the necessary wavelength component in the radiation component from the halogen lamp 1 is taken out by the membrane having the optical function to irradiate the gas to be detected outside the lamp. The concn. of the gas is detected from the resistance between the electrodes 8, 9 of the gas detection layer corresponding to the concn. of the gas. Since the membrane having the optical function taking out only the necessary wavelength component and the gas detection layer are integrated, the lamp can be used as the heat source for the gas detection layer and the structure of the apparatus can be simplified.

Title: Photosensitive material and image forming method
Inventor: YAMADA MASATO
IPC: G03F7/004
Filed: 1989-03-24
Abstract: PURPOSE:To allow stopping of development in correct development time and to improve preservable stability by incorporating a specific restrainer precursor into a photosensitive layer. CONSTITUTION:The development restrainer precursor expressed by the formula I is incorporated into the photosensitive layer. In the formula, A denotes the development restrainer bonded via a hetero atom or a group which can release the development restrainer by succeeding reaction after elimination; Y denotes an arbitrary atom or group; Z denotes an atom group necessary for forming a carbon ring or heterocycle. The excess progression of the development is suppressed in this way and the generation of unequal images, etc., probably generated by a slight fluctuation in developing temp. is averted even if such fluctuation arises. The good image is thus obtd. Further, the stable image is obtd. as the stability with age is high.

Title: Control method for electric motor vehicle
Inventor: JIZOU YOSHIHIRO
IPC: B60L7/12
Filed: 1979-06-08
Abstract: PURPOSE: To permit smooth control from a high speed to an extremely low speed by operating rectifiers after the operation of a thyristor type semi-bridge rectifier and inverter wherein the vehicle speed is reduced and a motor current is controlled constantly by setting the rectifier voltage at zero.  
     CONSTITUTION: Firstly, as shown in 1 in figures, regeneration control is performed by the inverter operation of rectifiers under the condition of DC no load voltage Edo<0, namely, under the condition that a thyristor control lagging angle γ in the rectifiers MRf is larger than a thyristor control leading angle β. Next, as shown in 2, after the condition of γ=β and Edo=0, the condition of Edo>0 is maintained by consecutively proceeding the rectifiers to the rectifier operation as shown in 3W5. Then, on detecting that the vehicle speed has reduced and become below a predetermined final step reference speed, the rectifying voltage Edo is gradually decreased to reduce a main motor current. Finally, the vehicle is smoothly stopped by operating a pneumatic brake or the like.

Title: Bearing cooling ventilation structure of dynamo electric machine
Inventor: YAMATO ATSUSHI
IPC: H02K5/20
Filed: 1995-03-30
Abstract: PURPOSE: To increase the volume cooling air which passes an air-cooling oil cooler and to minimize the volume cooling air passing through a cooing fin by providing a bypass wind tunnel for guiding cool air after passing through an air-cooled oil cooler from the other side of a bearing to a rotor or a stator. CONSTITUTION: The lower edge part of a generator shaft 10 is supported at a lower bracket 13 so that it can freely rotate and a cooling fin 14 is formed at the outer periphery of a lower guide bearing oil bath 6. Therefore, by rotating a cooling fan 3 along with a rotor 5, cooling air is guided from outdoors to the inside of a power station as shown by an arrow for cooling a stator 4 and a rotor 5 and is delivered outdoors through an exhaust wind tunnel 7. One portion of the cooling air which passed through an air cooled oil cooler 2 and cooled a thrust bearing oil bath 1, passes from upper to lower part in a bypass wind guide 8, passes near the cooling fin 14, and is guided to the stator 4 and the rotor 5.  However, the cooling air passing through the bypass wind tunnel 8 is not guided to the lower guide bearing oil bath 6 and should be the minimum air volume required for passing the cooling fin 14 as conventionally.

Title: Sheet material transport device
Inventor: OKAMURA SHIGERU
IPC: B41J11/00
Filed: 1988-03-29
Abstract: PURPOSE:To uniformize each single transport value to a specified degree with high accuracy by constituting each gear composing a gear train in such a manner that the quotient obtained by dividing the rotating angle of the gear for transporting sheet material by a specified single transport value by a rotating angle corresponding to the single tooth pitch of said gear is an integer. CONSTITUTION:The rotary drive of a paper feed roller 6 is carried out by transmitting the rotary driving force of the paper feed motor to the paper feed roller 6 through a reduction gear mechanism consisting of four gears G1-G4. The gears G2, G3 rotate by rotational drive of the gear G1 by the paper feed motor, then the gear G4 rotates to a direction B and the paper feed roller 6 is driven by rotation to the same direction. After this, if each gear G1-G4 is set in such a way that th quotient obtained by dividing the rotating angle of the gear by a rotating angle phi deg. corresponding to a single pitch PO of gear tooth is an integer, a single transport enables the gear to rotate at a rotating angle equal to the integral multiple of the rotating angle phi deg. of a tooth pitch. Therefore, the gear is set to the same stop phase at every transport stop. Consequently, each gear is engaged in the same condition and thus each transport value can be uniformized to a specified degree with high accuracy.

Title: Adhesive composition
Inventor: FUJII ICHIROU
IPC: C08K3/16
Filed: 1983-04-26
Abstract: PURPOSE:To provide an adhesive composition which has a relatively long pot life but cures quickly under high frequency heating to form an adhesive layer with excellent durability, prepared by adding AlCl3 as hardener to a precondensate of phenol-modified urea resin. CONSTITUTION:The adhesive composition is prepared by adding 0.5-3pts.wt. AlCl3 as hardener to 100pts.wt. precondensate of phenol-modified urea resin. Urea resin adhesive has an extensive use in bonding of wood and, when high frequency heating is employed, a filler such as wood flour and a hardener such as citric acid are added to improve the durability of the adhesive, but the adhesive has disadvantages in that it has a short pot life after addition of the hardener and does not cure in a short time under application of high frequency. When AlCl3 is added as hardener, the adhesive has a relatively long pot life and cures quickly by high frequency heating to form an adhesive film with excellent durability.
