Title: Optical disk device
Inventor: SATO KENICHI
IPC: G11B7/121
Filed: 1990-04-19
Abstract: PURPOSE:To allow even a general user who does not know the device constitution to easily perform the dust removing work by blowing air flowing from a inflow port to the light outgoing face of a fixed optical part and the light receiving face of a movable optical part from first and second outflowing ports. CONSTITUTION:At the time of cleaning the light outgoing face 20a of a beam splitter 20 and the reflecting face 21a of a prism 21, a rubber stopper 26 closing the inflowing port 23c of an air guiding member 23 is pulled out, and the tube 27a of a blower 27 is connected to the inflowing port 23c. When air is sent with a pressure by the blower 27, air from the tube 27a flows into the duct 23A of the air guiding member 23 from the inflowing port 23c and is branched to the right and the left by the duct 23B. Since outflowing ports 23a and 23b are opposed to the light outgoing face 20a of a beam splitter 20 and the reflecting face 21a of a prism 21, air blown off from outflowing ports 23a and 23b is blown to the light outgoing face 20a and the reflecting face 21a to remove stuck dust. Thus, exposed parts of the fixed optical part 17 and the movable optical part 18 are cleaned to secure the detection precision of the laser beam.

Title: Circulative water heating type hot-water reservoir tank
Inventor: SHIMAKURA KOUSHIROU
IPC: F24H1/18
Filed: 1979-08-16
Abstract: PURPOSE:To securely creat a rapid convection, conduct a heat exchange at high efficiency and obtain hot water of a uniform temperature by a method wherein an auxiliary tank is placed above a main tank provided therein with a heating member, and the tanks are connected with eath other through an up-flow pipe and a down- flow pipe. CONSTITUTION:An auxiliary tank 2 not provided with any heating member is placed above a main tank 1 provided therein with a heating member 3. The high- temperature water heated by the heating member 3 flows upwards through an up- flow pipe 5 into the auxiliary tank 2, while the low-temperature water in the auxiliary tank 2 flows downward through a down-flow pipe 6 into the main tank 1. In this way, a rapid convection is created securely and an efficient heat exchange is conducted. When a temperature set on a temperature sensing member 12 is attained, a regulating valve 13 functions to stop the supply of the heating source. Accordingly, the hot water taken out via a hot-water feed port 7 is kept at a substantially uniform temperature. In addition, since the auxiliary tank is free of heating members, there will arise no problem on metal corrosion.

Filed: 1989-04-25
Abstract: PURPOSE:To secure a prescribed error rate without being affected by temperature change or the lapse of time by setting an offset value to decrease the error rate of a signal read from a recording medium. CONSTITUTION:At a state of standby, write, or erasure, a control part 10 connects a change-over switch 11 to an address selection side. An error detecting part 12 discriminates the presence/absence of the code error and the sequence error of an address, and a calculating part 13 counts the number of errors generated within fixed time. When the number of errors exceeds a normal value, a setting part 14 sets a new offset value on a storage part 15, and adds it on the controlled variable of the output of a control part 17 by an addition part 18. By repeating such operation, the offset value to reduce the error of the address recorded on the recording medium can be selected. At a reading state, the control part 10 connects the switch 11 to a data selection side. The detecting part 12 discriminates the presence/absence of the code error in the data, and the calculating part 13 counts the number of generation of the error within the fixed time, and the setting part 14 sets the offset value so as to reduce the number of errors.

Abstract: PURPOSE:To improve friction characteristics and durability by specifying the Vickers hardness of a plasma-polymerized film provided on the thin ferromagnetic film on a base body to a prescribed value. CONSTITUTION:A body 1 to be deposited is imposed on one electrode 25 of electrodes 21, 25 facing each other in a vacuum chamber. An RF voltage is impressed between the electrodes 21 and 25 and a negative bias voltage is impressed to the electrode 25. Plasma is generated between the electrodes 21 and 25 by the RF electric field when a source gas is admitted between the electrodes 21 and 25. The cations in the plasma are brought into collision against the body 1 to be deposited by which the plasma-polymerized film is formed on the thin ferromagnetic film on the base body 1. The plasma- polymerized film contg. carbon and hydrogen is more preferable as the polymerized film. The Vickers hardness HVp of the plasma-polymerized film is specified to the value of 0.8 to 1.2 times of the Vickers hardness HVn of the magnetic head in, for example, a 600 to 3000kg/cm<2> range.

Title: Roll paper feeder in electrophotographic apparatus
Inventor: ITOU TAKASHIGE
IPC: B26D7/06
Filed: 1979-08-17
Abstract: PURPOSE: To prevent adverse influence to be given on images by providing paper width detecting means and memory means for the minimum cut length of every paper width obtained from the amount of the slack formed and preventing the cut of less than the minimum cut length from the outputs thereof.  
     CONSTITUTION: A counter circuit starts counting by the signal from the pulse generating circuit which generates pulses according to the revolutions of paper feed rollers 2. It produces an output when the pulse count number having been selected by the paper width signal is reached. A latching circuit, upon receiving said output, makes latching operation to AND this and the original tailing end signal from an original detecting circuit and inputs the output thereof to a cutter driving circuit. Even if the original tailing end signal comes before the amount of paper feed reaches the minimum cut length for the paper width no outputs are generated, and at the time when the original tailing end signal comes after the minimum cut length, an output is generated so that a cutter 3 is operated by way of the cutter driving circuit. At this same instant, the drive roller 2a is stopped. In this way, the adverse influence to be given on images may be prevented irrespective of paper width.

Title: Image forming method and device therefor
Inventor: YUASA TOSHIYA
IPC: B41M5/30
Filed: 1990-04-23
Abstract: PURPOSE:To mitigate a pH change on an ink surface and compensate the shortage of water content to improve a stability in image forming by providing a means for applying an acid liquid to the ink surface to which a voltage is applied. CONSTITUTION:An ink holding roll 1 has a positive polarity and a plate 4 has a negative polarity. Ink 2 has properties that the surface on the negative polarity side changes from adherent to non-adherent. Therefore, after the application of a voltage, the surface of the ink 2 becomes non-adherent. Namely, on a conductive image pattern provided on the plate 4, the ink becomes non- adherent, generates hydrogen gas mainly by an electrolysis of water, and exhibits a strong basicity. As a result, the water content on the surface of the ink remaining on the ink holding roll without adhering on the plate is lost, and the ink is increased in electric resistance and pH value, thus resulting in the reduction of viscosity and the increase of adhesion. If the voltage is still repeatedly applied, the ink hardly becomes non-adherent. To prevent this phenomenon, an acid liquid is infiltrated in a porous roll 10 and brought into contact with the surface of the ink 2 applied with a voltage.
