Title: Image forming device
Inventor: OGATA TAKAO
IPC: G03G15/08
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To realize the stable replenishment of toner and to obtain an image with appropriate density by correcting the replenishment of toner by a video count system density control means in accordance with the detection output of the density of a patch image by a patch detecting system. SOLUTION: The specified patch image is formed in a non-image area on a photoreceptor drum(S5), and developer density T/C  toner weight/(toner weight + carrier weight)} is detected by detecting the density of the patch image by a sensor. Density variation ΔD1 is obtained from the detected developer density and a reference value so as to judge whether the variation ΔD1 is within ±1 wt.% of the reference value(S6). When the variation of T/C is within ±1.0 wt.%, it is fed back to the replenishment table of the video count system density controller and video count system density control is performed while changing the replenishment table. When the T/C is >=±1.0 wt.%, the video count system density control is stopped and the patch detecting system density control is performed (S7).

Title: Manufacture of piezo-electric polymer film
Inventor: KOBAYASHI TERUO
IPC: H01L41/45
Filed: 1980-11-10
Abstract: PURPOSE:To produce piezo-electric polymer films by a method wherein a lamination of several polymer films including at least a sheet of piezo-electric polymer travels between a pair of electrodes supplied respectively with positive and negative potentials for polarization. CONSTITUTION:Three films 1-3 are laminatedly fed in, one of the three a PVF2 film and the others pinhole-free films made of polyimide or the like. Units 8 and 9 generate high voltages of different polarity and emit electric charges of reverse polarity, the emitted charges of two types fixed upon the polymer films due to mutual attraction. High voltage impressing units 18-25 are provided within and without of a thermostatic oven 34 where electric fields generated by the electric charges and a pair of high voltage impressing units cause dipoles in the films to migrate causing polarization. Time needed for polarization is kept constant by adjusting the length of the thermostatic oven 34 and the number of high voltage impressing units, in view of the film feeding speed. The films begin to be polarized at room timperature and remain the same throughout the heating and cooling processes. This realizes a stable, uniform polarization of high piezo-electric effeciency.

Title: Differential pressure transmitter
Inventor: FUKAI WATARU
IPC: G01L27/00
Filed: 1990-06-19
Abstract: PURPOSE:To make a zero-point adjustment with a small error by providing a mechanism which closes a by-pass by a valve mechanism at the time of a differential pressure detection to lead diaphragm pressure to a detecting element and opens the bypass at the time of the zero-point adjustment to eliminate a pressure difference between both surfaces of the detecting element. CONSTITUTION:The valve mechanism 12 is provided at the center part of the by-pass 11 and closed at the time of the differential pressure detection to separate the high-pressure and low-pressure sides of a U-shaped pressure medium passage 9, thereby leading pressure Pa and Pb applied to respective diaphragms 7 to the surfaces of the differential pressure detecting element 10. When the zero-point adjustment is made, the valve mechanism 12 is put in operation to open the by-pass 11 for a short time and link the low-pressure side downstream part 9bb and high-pressure side downstream part 9ab of the passage 9 with each other, thereby applying equal pressure to the surfaces of the element 10. Consequently, the zero-point adjustment can be made with a small error only by external switch operation without operating a three-valve mechanism installed outside the differential pressure transmitter.

Filed: 1979-12-07
Abstract: PURPOSE:To reduce the expansion and the liquid leakage of button-type battery, by removing the copper of the rim of the cathode to make the stainless-steel which is hardly amalgamated to be exposed. CONSTITUTION:A clad plate as a material of a cathode can, which is constituted of a pure copper 1 and a stainless steel 2, undergoes a plastic working and is provided with a concave part. The copper surface of a rim 2a of the cathode can is removed by polishing or the like to make the stainless-steel of the rim 2a to be exposed, before the circular periphery is turned to form a surface 2a' making contact with the gasket 4. Following that, an amalgam layer 3 is produced over a bottom surface 1b of the cathode can, which is covered with copper, by means of a wet batch treatment. Owing to the above constitution, the gasket 4 is made to be in contact with the stainless-steel layer 2a' of the cathode can 2 which may not be amalgamated. Besides, the connecting of an anode can crook the gasket 4 and makes the gasket 4 closely touch a turned part 2c. Thus, no copper is interposed between the gasket 4 and the cathode can, and any expansion as well as liquid leakage of a button-type battery can be prevented.

Title: Gas vent valve
Inventor: ICHIKAWA MAKOTO
IPC: B65D33/01
Filed: 1989-06-20
Abstract: PURPOSE:To retain sufficient airtightness in a gas escape passage without using a liquid seal and smoothly and surely open a valve at the generation of gas so as to dissipate the gas to the outside by utilizing as the gas escape passage a clearance which is formed when an enclosing film is raised by the internal pressure of a packaging body, which pressure is raised by the gas generated. CONSTITUTION:When packed articles in a packaging bag generate gas and so the internal pressure of the packaging bag is converted to high pressure, then the high pressure gas is allowed to pass through the gas escape portion of the packaging bag and presses an enclosing film 3 from the circular hole 6 of a base film 2 against the pressing force of a valve 4 to form a clearance between the films 3 and 2. The clearance is utilized as a gas escape passage and the gas is dissipated to the outside from released, non-adhering portions 11, 11 at both ends of the film 3, so that the internal pressure of the packaging bag is prevented from rising abnormalily high. When the gas in the packaging bag is dissipated the clearance is closed directly by the recovering action of the film 3, the valve 4 and a control film 5, and the film 3 is stuck to the film 2 and so the passage is surely blocked without using a liquid sealing agent of silicon oil and the like in the clearance and fresh air entering the bag is blocked to prevent contents from being deteriorated.

Abstract: PURPOSE:To improve the liquid spill preventive property by applying a laminating process on the surface of the rubber plug of a medical care container in which a rubber plug presser foot is fitted on the upper side of a mouth main body and the rubber plug. CONSTITUTION:A rubber plug 3 is fitted to a mouth main body 2, and a rubber plug presser foot 4 is fitted on the upper side of the main body 2 and the rubber plug 3. In this case, a laminating process is applied to the surface of the rubber plug 3, and the rubber plug 3 of the mouth 1 is calking-fitted by an ultrasonic welder between the main body 2 and the rubber plug presser foot 4. A medical care container 32 is composed by installing the mouth 1 to a container 33 in which a medicinal liquid is filled. As a result, since the elasticity restoring force of the rubber plug 3 is rapid, a liquid spill from the penetration hole of a needle when the needle is removed after the needle is inserted to the rubber plug for a long time can be prevented surely. And, since the sealing property is maintained in a transporting condition or when the inside of the medical care container is in the pressurized condition, the liquid tight property is excellent, and a trouble such as a drop of the rubber plug in the container is never generated, and the medicinal liquid in the container 33 can be extracted safely.
