Title: Disc device
Inventor: YAMAMOTO MASANOBU
IPC: G11B7/007
Filed: 1984-10-22
Abstract: PURPOSE:To separate and reproduce a clock signal and an information signal by detecting an intensity-modulated reflected light to reproduce the clock signal and detecting differentially reflected lights in the first and the second directions as rotation directions of the plane of polarization to reproduce the information signal. CONSTITUTION:A photomagnetic disc device inverts the magnetization direction of a vertically magnetized film on an optical disc to record signals. The reflected light from the magnetic film is divided into two by a half mirror, and divided reflected lights are detected by individual photodetectors after passing individual detectors provided for upward magnetization and downward magnetization, and signals are reproduced by the differential output. A pregroup 1 of the photomagnetic disc consists of address bits 2 having lambda/4 depth and a group 3, and the information signal is recorded on the group 3 with an amplitude sufficiently shorter than lambda/8 with lambda/8 depth as the center. Thus, the rotation of the disc is controlled to a certain linear speed by the clock signal formed on the group 3 to reproduce the information signal by the differential detection method.

Title: Dehumidifying membrane and production of dehumidifying membrane
Inventor: SAITO TOMONARI
IPC: B01D71/10
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To improve the tolerance and film strength of a dehumidifying membrane, to suppress permeation of air and to maintain excellent removing performance of water vapor by laminating a hydrophilic organic polymer material in a thin film state on the surface of a porous base body having micropores. SOLUTION: The dehumidifying membrane 1 is produced by laminating a chitosan thin film 3 as a hydrophilic organic polymer material on the surface of a porous alumina hollow fiber 2. The chitosan thin film 3 is formed as a homogeneous and dense thin film layer on the surface of the porous alumina hollow fiber 2 so as to use such a phenomenon that the thin film layer in contact with water vapor dissolves and diffuse moisture to separate as well as to secondarily use the capillary condensation phenomenon of moisture in the pores of the thin film. The pore diameter of the micropore is specified to <=5 μm. Thereby, the tolerance and film strength of the dehumidifying membrane 1 against a mist component such as oil in air can be improved and permeation of air is suppressed to maintain excellent removing performance for water vapor.

IPC: B41J35/16
Filed: 1986-09-22
Abstract: PURPOSE:To reduce a printing cost by storing a range corresponding to a region of a transfer sheet to be transferred with ink of a transfer sheet if the ink is available in an ink range that the range is read, executing a transfer printing, and reading the other ink range if it is not available. CONSTITUTION:A region A to be transferred with ink of a transfer sheet on a recording sheet 1 is decided on the basis of an input signal of an information signal to be printed. Data relative to the ink at N-th position of the transfer sheet input to a memory 2 is read, and comparison judging means 3 jndges whether the region A is contained or not therein. If the region A is not yet used by the transfer sheet of the N-th position by this judgement, data of one use is input to the memory 2 with respect to the data corresponding to the region A at the N-th position. Simultaneously, this ink range is fed, transferred and printed. If the part corresponding to the region A is always used, other ink range is read. Thus, the ink using efficiency is improved.

Title: Printer
Inventor: KAZAMA YUUJI
IPC: B41J5/30
Filed: 1983-11-25
Abstract: PURPOSE:To enable data to be securely received even when the data-transmitting speed is high, by a method wherein the driving condition of a controlling motor is detected, and a busy signal or a ready signal is outputted, in a printer using a type wheel. CONSTITUTION:A CPU1 inputs character codes or the like from a host computer into an interface controlling part 6, and when an interrupt signal of a timer 7 is inputted, the CPU1 calculates the moving quantity and the rotating direction of a type wheel motor 11, and sets the calculated values into a RAM4. Then, a busy signal is outputted to the host computer through a transmission line 5 to prevent new interrupt data from being transmitted, and the timer 7 is started to drive a motor, thereby printing out a corresponding character. When the driving condition is completed, a ready signal indicating that data can be received is outputted. Accordingly, even when the speed of transmission of data with an external controlling part is high, the data can be received securely, can be processed without affecting the driving of the controlling motor, and a normal printing-out operation can be maintained.

Title: Phase-locked loop circuit and jitter control method
Inventor: RAMU KERUKAA
IPC: H03D13/00
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a jitter control method for a highly flexible PLL which causes nearly zero feedback delays, is hardly immune to substrate noise nor power supply noise, and can operate at a wide range of frequencies. SOLUTION: The PLL incorporates a phase/frequency detector 10 which uses a dividing circuit and feedback from a clock distributing tree to generate increment and decrement pulses having no 'dead zone'. A jitter is generated when the frequency of a reference clock circuit fluctuates. In a phase locking state, large quantities of currents are gated by charge pumps 14 and 16 in response to the increment and decrement pulses and, in a locked state, small quantities of currents are gated by the pumps 14 and 16. Since the quantities of the currents are reduced, the occurrence of jitters is reduced when the PLL is in the locked state.

Abstract: PURPOSE:To miniaturize the machine in the caption according to a method wherein the machines main body for supporting rotatably a plurality of winding drum shaft is rotatably supported, the same number of motor as that of winding drum shaft are mounted, while those drive motors are coupled with the winding drum shafts via a gear mechanism. CONSTITUTION:Machine's main body 2 is put in revolution by means of revolving motors so that 2 pieces of winding drum shaft 1a, 1b may be replaced with each other with respect to their shaft centers. This revolving mechanism is identical to the conventional system in which a revolving drive motor installed on the foundation acts as a power supply and the machine's main body 2 is rotated by means of gears engraved on the periphery of the machine's main body 2 and other gears meshing with the former gears. In this case, drive motors 7a, 7b for winding drum shafts 1a, 1b turn around a support roller 5 playing the role of reference shaft, while their attitudes being upside down together with the machine's main body 2. During this period, the drive motors 7a, 7b are either in rotation or stationary, but brushes are mounted in both of them for the purpose of supplying power continuously. For this purpose, the driving system has been remarkably simplified, resulting in reduction of the overall machine size and in compactness.
