Title: Magnetic head device
Inventor: SHIMIZU MAKOTO
IPC: G11B25/04
Filed: 1990-03-08
Abstract: PURPOSE:To improve the read accuracy by giving a difference to an energizing force of an energizing means to make a top of a magnetic head onto a card closely so that the card is pressed to any card guide. CONSTITUTION:A spring force of a 1st spring 15 is set stronger than a spring force of a 2nd spring 21. Thus, a pressing force F1 of a magnetic head 5 pressing a magnetic head 1 to a lower side card guide 10 is stronger than a pressing force F2 of a magnetic head 7 pressing the magnetic head 1 to an upper side card guide 9 and the card 1 is retained by the guide 10. Thus, when the card 1 passes the position of the heads 5,7 of a card path 11, the card 1 is positioned toward the guide 10 and read cores 5a, 7a are in contact with magnetic stripes of the card 1 at a proper contact pressure and the content of the magnetic stripes is read. Thus, it is possible to increase the read accuracy.

IPC: H04B1/707
Filed: 1995-02-20
Abstract: PURPOSE: To shorten the synchronization acquisition time of a control station by acquiring synchronization by phase pull-in from the reference clocks of the control station for respective mobile stations at all times in a reception part inside the control station for generating master clocks and canceling the holding of phase information at the time of transmission. CONSTITUTION: When the control station receives transmission enable signals, a control part 101 sends transmission timing signals from a spreading code generator 103 through a selector 102 to a synchronization part 104. A VCO is controlled so as to synchronize the signals and the generation timing of spreading codes for reference of an inverse spreading code generator 105 and clocks are synchronized. When the transmission is ended, a peak detection circuit 107 detects reception from the mobile station and measures prescribed preamble reception time and the synchronization part 104 acquires the synchronization of peak signals and the generation timing of a reference spreading code and holds clock phase information.  Thus, the phase pull-in from the reference clocks of the control station is performed for respective reception mobile stations at all times, the synchronization is acquired and the acquisition time is shortened.

Title: Temperature detector
Inventor: OZAKI KAZUYUKI
IPC: G01K11/12
Filed: 1988-03-09
Abstract: PURPOSE:To detect the temperature of an optical waveguide by guiding light by the optical waveguide which varies in refractive index with the temperature and detecting the projection position of the light from the optical waveguide. CONSTITUTION:The light which is guided from a light source 11 by an optical fiber 12 is made incident perpendicularly on a 1st optical fiber 13 made of a material (inorganic glass, etc.) which does not vary in refractive index so much with the temperature. A 2nd optical waveguide 14 made of a material (polymethyl methacrylate, etc.) which differ in refractive index from the optical waveguide 13 and varies with the temperature is arranged adjacently to the projection end of the optical waveguide 13. When the light L projected from the optical waveguide 13 is incident on the optical waveguide 14, the refractive index of the optical waveguide 14 varies with the temperature, so the projection position D also shifts with the temperature. The shift in this projection position D with the temperature is detected by a photodetector 15 to detect the tempera ture of the optical waveguide 14.

Title: Roll for cold rolled steel strip excellent in gloss in tandem rolling and cold rolling method using the same
IPC: B21B1/22
Filed: 1992-03-13
Abstract: PURPOSE:To manufacture a product excellent in surface gloss with high productivity by imparting spiral-mark-like roll grinding marks in the range of a specified angle to the rolling direction in the work roll of a cold tandem mill. CONSTITUTION:The roll grinding marks is spirally imparted to the work roll having an angle theta of 50 to 60 deg. to the rolling direction. A 4 stages rolling mill using a forged steel roll whose grinding marks have a spiral angle of theta of 10 deg. to the rolling direction for the work roll is taken as an sample. As a result of setting a stainless steel using high viscosity rolling lubricating oil for the rolling lubricating oil and executing rolling under prescribed rolling conditions, the surface glass is improved about twice the conventional gloss. To improve the surface gloss further, it is preferable to use the work roll on which the spiral marks are imparted for the 1st stand also in addition to the final stand. In this way, the product excellent in surface gloss is obtained and also rolling speed can be increased, because the work roll is excellent in seizure resistance too.
