Title: Method of covering inner surface or inner and outer surfaces with plastic film
Inventor: OZAKI SHIGEO
IPC: B65D81/24
Filed: 1979-04-09
Abstract: PURPOSE: To cover an inner surface of a container with a film and simultaneously cover inner and outer surfaces of a container with a film irrespective of the presence of permeability, by a method wherein a plastic film is stretched in a chamber wherein a container is placed, and gas is fed into from a film side under a decompressing condition.  
     CONSTITUTION: A container 2 is placed on a container rest 3 in a chamber 1, and a plastic film 4 is stretched over the container 2. The chamber 1 is then closed with a cover 9 lowered. And thereby the chamber is sealed in such a condition as causes the plastic film 4 to be positioned between the nip formed by the cover 9 of the chamber and a packing 8 situated at the end of the chamber 1. The pressure in the chamber 1 is reduced by letting air out of the chamber through vacuum holes 6 and 7, and simultaneously, the plastic film 4 is softened by heating by means of a heating plate 5. When gas is supplied from the film (4) side, the container is simultaneously pressed enoughly against the plastic film 4 by pushing upward the container rest 3. Since the plastic film 4 is softened, it is adhered in correspondence with the configuration of the container 2 by the gas pressure and the force of the container 2 pushed upward.

Abstract: PROBLEM TO BE SOLVED: To induce charges directly in a film coating the outer circumference of a drum by arranging a drum to be applied with a bias voltage, a semiconductive film having a specified volume resistivity coating the outer circumference of the drum, means for printing on a recording medium, and the like. SOLUTION: When a recording medium 9 is carried to a predetermined position, a conductive charging roller 22 made of urethane, rubber, or the like, having volume resistivity of 10<4> -10<6> Ω.cm is brought into contact with the surface of a recording medium 9 and the potential from a bias power supply 25 is applied to the recording medium 9 through the charging roller 22. For example, a potential of -200V is applied to the recording medium 9 and a predetermined voltage is applied from a predetermined bias power supply 21 to a drum 8. Consequently, charges are transported through a semiconductive film 18 (volume resistivity is 10<9> -10<14> Ω.cm) applied to the outer circumference of the drum 8 to the surface thereof and the potential on the surface of the drum 8 is equalized to the potential on the surface of the film 18.

Abstract: PURPOSE:To provide a constantly favorable closely-fit condition b energizing the part of a seat which is closely fit to a valve body by means of a metal spring whose characteristic is less apt to be varied with variation in temperature so as to force the seat onto a valve body at a certain pressure. CONSTITUTION:A closely fitting part F having a cantilever-like section is disposed on the inside of a ring-like seat 1. A base of the closely fitting part F is located at a larger diameter side of a valve body 3 having truncated conical section. This base is also equipped with a hinge H while, the end of the closely fitting part F is energized by a metallic spring 5 so that an internal periphery 1a and an external periphery 3a are closely fit throughout those circumferences and the widths. In case said members are used for a fluid pipe of an extremely low temperature, a leakage which is caused by a loss in elasticity of the seat 1,  which is made of high molecular materials may be prevented because the hinge  H provided for the closely fitting part F can provide said closely fitting part F  with the susceptibility to deflection in response to a load of the spring 5.

Title: Engine control device
Inventor: MIKI MASAYUKI
IPC: F02D41/00
Filed: 1988-02-27
Abstract: PURPOSE:To carry out an air-fuel ratio control in the whole operational area containing the area of immediately after the engine starting, for a prescribed period elapsed from engine starting, by carrying out an air-fuel ratio control based on data for expressing the experience of the air-fuel ratio on the last operation. CONSTITUTION:When an engine is started, a CPU 5 carries out firstly an initial process, while starting a timer at the same time. And then, a real air-fuel ratio obtained on the last starting at the same water temperature, is read out of a memory 6, so that a fuel amount with a correction added to a set air-fuel ratio, is supplied into the engine. This action is repeated for a period until an air-fuel ratio senser 1 exhibits a normal output value, namely, for a period until the timer is less than a prescribed value. In addition, when the timer exceeds the prescribed value or more, the CPU 5 judges that the airfuel ratio senser 1 is in an operationable condition so as to take in the output from the air-fuel ratio senser 1. This value is converted into the value of the air-fuel ratio so as to be stored in an address corresponding to a water temperature at the time of starting of a memory 6 as a new air-fuel ratio information. Thereby, when the engine is operated, it is possible to obtain always pertinent air-fuel ratio control.

Title: Flow control valve and air conditioner
Inventor: SARUHASHI KOICHI
IPC: F16K31/66
Filed: 1995-03-03
Abstract: PURPOSE: To simplify flow control and reduce facility cost by providing a thermal expansion member capable of expansion and contraction depending on a temperature change for displacing an operation member, as well as a heating means for the expansion member, and adjusting the open/close degree of a valve via the operation member under the control of a heating variable. CONSTITUTION: When a thermal expansion member 116 is heated with a heater 108 and subsequently expands under the supply of electric power, a shaft 112 moves in an arrow A direction. Thus, a valve fitting 120 secured to the shaft 112 as well moves in the same direction, and a gap between the fitting 120 and a valve 122 expands. As a result, a larger volume of hot water stagnating in a zone 53A passes space between the fitting 120 and the valve 122 under the prescribed pressure in an arrow B direction. Then, the hot water passes a zone 53B and reaches a zone 53C. When power supply is interrupted, the heater 108 stops heating the member 116, and this member 116 contracts, thereby causing the shaft 112 and the fitting 120 to move in a direction opposite to the arrow A. In addition, the gap between the fitting 120 and the valve 122 narrows, and a hot water flowrate in piping 53 drops.  According to this construction, flow control can be simplified and facility cost can be reduced.
