Title: Electromagnetic driving apparatus
Inventor: FURUKAWA AKIRA
IPC: F16K31/06
Filed: 1982-07-21
Abstract: PURPOSE:To improve response and to enable to execute linear control without use of an external compensating circuit, by using two pulses and driving an output shaft by the unbalance of the electromagnetic forces produced by a first and a second electromagnetic coils. CONSTITUTION:A voltage for driving a coil 13B is obtained at a point (b) by comparing a lamp wave form R with an analogue instruction voltage varied by a variable resistance R1 by means of an electromagnetic comparator A2. The voltage at the point (b) is inverted by a voltage comparator A3 for obtaining a voltage at a point (c) used for driving a coil 13A. The voltage signals at these points (b) and (c) are utterly antiphase. With such an arrangement, the position of a valve body is controlled by driving the coil 13B or 13A by impressing the voltage at the point (b) or (c) on the base of a driving transistor Q1 or Q2.

Title: Data detector and its method
Inventor: JEON JIN-KYU
IPC: G11B20/10
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To improve maximum likelihood decoding performance. SOLUTION: This detector 200 consists of a converter 202 for converting a reception signal into a digital signal data in response to a sampling clock signal, a maximum likelihood decoder 204 for performing maximum likelihood decording on the digital data and a generator 206 for generating a control signal for detecting a phase difference between a sampling point of the digital data and an optimum detecting point of the reception signal and changing a phase of the sampling clock signal to correspond to the detected phase difference. The phase of the sampling point as a data detecting point and the phase of the optimum detecting point are made to coincide with each other, so as to minimize an error caused by the phase difference, and hence the performance of the maximum likelihood detector, i.e. the detecting performance of the reproducing data is improved.

Title: Housing board
Inventor: HIJIKATA KENJI
IPC: H02B1/30
Filed: 1995-05-26
Abstract: PURPOSE: To prevent temperature rise in a housing board and to prevent visibility by using an incident-light control member, whose transparency is changed by current conduction, for the glass window of the housing board, switching transparence and opacity of the window glass by the change in brightness around the board and a touch sensor, and shielding the incident light through the window. CONSTITUTION: The switching of the transparence and opacity of a glass window 2 is controlled with a first control part 4 and a second control part 6. The first control part 4 turns on the current conduction to an incident-light control member when the surrounding part is bright in correspondence with the brightness of the surrounding part detected with a brightness detecting part 3, and the window 2 is made opaque. When the surrounding part is dark, the current conduction is turned off, and the window is made transparent. The second control part 6 touches a touch sensor 5 when the window 2 is made transparent, turns off the current conduction to the incident-light control member constituting the window 2 and switches the member to transparence.  When a person touches the touch sensor 5, the second control part 6 turns off the current conduction for the specified time by a timer, and the window 2 is made transparent. Thus, the rise of the inner temperature is prevented, and the inner part is readily inspected.

In that case, the cast film is dried by a predrying process wherein the solvent is evaporated until a content of the solvent becomes 5-25wt.% to form a predried film having a self-supporting property, and a postdrying process wherein the predried film, after peeled off from a base material, is dried by heating under a state capable of being shrunk in width direction.  Then, a drying temperature (T deg.C) is raised conforming to change of Tg' so as to satisfy Tg'-50<T<Tg' (where Tg' deg.C is a glass transition temperature of an aromatic polyether sulfone film containing a residual solvent).

Title: Cleaning sheet
Inventor: UCHIDA KOTA
IPC: B65H5/00
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To prevent a carrying roller from the adhesion of paper powder to deteriorate the carrying precision of a recording material slipped in carrying by using a synthetic resin elastic body as the material of a cleaning sheet. SOLUTION: This cleaning sheet CS is nipped and carried between a carrying roller 4 and a pinch roller 5, whereby the paper powder adhered to the surface of the carrying roller 4 is transferred to the cleaning sheet CS to remove the paper powder adhered to the surface of the carrying roller 4. Since the cleaning sheet CS is formed of a synthetic resin elastic material 12, the cleaning sheet CS can be deformed along the irregular form of the surface of the carrying roller 4 to adhere the paper powder fitted to the recessed part of the irregularities on the surface of the carrying roller 4 to the cleaning sheet CS side. Therefore, the paper powder fitted to the recessed part of the surface of the carrying roller 4 can be removed, and a recording material can be prevented from being slipped by the adhesion of paper powder to the carrying roller 4 to deteriorate the carrying precision.

Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device and its method capable of improving the operability by preventing a moloperation even in the case that an abnormality is caused at an automatic document feeder(ADF). SOLUTION: In the case that the ADF 2 is in a use-infeasible state (yes by step 401), the automatic selection function of copying paper is released (step 407), and the ADF 2 is set to be unable to be used (step 408), and the selection of the copying paper of a paper size which a user designates in a pressure plate mode is made possible. Thus, since the ADF is set to be unable to be used by releasing an automatic selecting means (= automatic selection function) in the case that the ADF is in the use-infeasible state, a whole device does not immediately stop operating and recording paper is selected by a designation selection means (= designation selection function) in the pressure plate mode. Thus, a moloperation can be prevented and also the operability can be improved.
