Patent JP-S6442262-A (JP)
Title: Thermal printer
Inventor: FUKUMOTO HIROSHI
IPC: B41J15/04
Filed: 1987-08-08
Abstract: PURPOSE:To bring a paper into close contact with the surface of a platen roller so that the paper can be fed without slippage on the platen roller at the time of printing and at the time of reverse feeding, by enabling the pressure exerted by each pinch roller to be switched according to the rotating direction of the platen roller. CONSTITUTION:When a thermal head 8 is lowered and a platen roller 9 is rotated in the direction of an arrow A to feed out a paper 3, the pressure exerted by a pinch roller 11 on the paper-supplying side is smaller than the pressure exerted by a pinch roller 10 on the paper-discharging side because a slide block 31 is moved in a direction E. Therefore, the velocity of feeding by the roller 11, and a slack generated in the paper at the time of supplying the paper is gradually removed. When the platen roller 9 is rotated in a direction B to return the leading end of the paper 3 to the position of a sensor 19 for detecting the leading end, the block 31 is moved in a direction F, and the pressure exerted by the roller 11 becomes greater than the pressure exerted by the roller 10. Therefore, the velocity of feeding of the paper 3 by the roller 11 becomes greater than the velocity of feeding by the roller 10, whereby a slack in the paper 3 is removed, and the paper 3 is set into close contact with the platen roller 9.

Title: Fiber ring interferometer
Inventor: SHIRASAKI MASATAKA
IPC: G01C19/72
Filed: 1993-08-10
Abstract: PURPOSE: To reduce influence of background scattering so as to prevent deterioration in a signal pulse by using a Sagnac effect optical fiber gyro in which a loop is constructed of a short part, which is made of a non-polarization maintaining fiber or a circular polarization maintaining fiber, and a linear polarization maintaining fiber. CONSTITUTION: A non-polarization maintaining(npm) fiber 46, in which double refraction 1/4 wavelength plates 48, 50 dividing a shift of polarized light are arranged at both ends, is connected to the intermediate position 44 in a loop 40 consisting of linear polarization maintaining(lpm) fibers 41, 42. The light 32 incident on a polarization beam splitter 34 is divided into two orthogonally crossing linear polarization pulses 36, 38 with equal intensity so as to be incident on the loop 40 in the opposite directions individually. The light is circularly polarized by means of the wavelength plate 48 and is returned to linearly polarized light by means of the wave length plate 50.  In this process, background scattered light 36bs accompanying the pulse 36 is circularly polarized in the opposite direction as it advances in the opposite direction and is emitted as linearly polarized light orthogonal to the pulse 36. Similar situation applies to the pulse 38, and the background scattered lights 36bs, 38bs of the pulses 36, 38 are eliminated by means of beam splitters 60, 62 individually and the result is made to be incident on a detector 26.

Title: Audio system
Inventor: ODA FUMIO
IPC: G11B15/10
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To enhance the operability after releasing an interruption mode by setting the interruption mode based on a priority of interruption stored in a priority memory area when the input operation of a single mode switching means is started under interruption mode. SOLUTION: When a mode key is depressed at a key operating section 16 under interruption mode, the relevant interruption mode is released. If an interruption mode is suspended with lower priority than the relevant interruption mode released based on an interruption priority stored at a memory section 17, the suspended interruption mode is set. When interruption of traffic information related to traffic mode is not ended, for example, a decision is made whether the system is interrupted with a route guide related to navigation mode. The processing is carried out based on the interruption priority stored at memory section 17 where the route guide interruption mode has higher priority than the traffic mode. When the system is interrupted with a route guide, the operating traffic mode is released and the route guide navigation mode is set.

Title: Guidance of moving object and scanning method of control light beam
Inventor: IMAMURA YOSHINOBU
IPC: G05D1/02
Filed: 1982-11-13
Abstract: PURPOSE:To form a complicated traveling route of a ground moving object with a simple device by turning a relfector which reflects and scans a laser beam around two axes orthogonal to each other. CONSTITUTION:A light beam LB is scanned along the traveling route of a ground moving object 3 which is previously set and stored. Thus the object 3 is guided. The turning angle is calculated for a reflector 11 which turns around two axes orthogonal to each other independently of each other from the traveling route stored in a microcomputer 101 through the above-mentioned scan of the beam LB. Thus step motors 13 and 15 are driven to turn the reflector 11. The laser beam LB sent from a laser generator 2 is swept in the form of a reflected beam LB'. The object 3 detects 31 the beam LB', and a steering driving circuit 302 and a steering motor 32 are driven after a route discrimination 301. Then the object 3 is guided along a prescribed route.

Title: Control device for openable rear window and wiper for vehicle
Inventor: WATANABE MAKOTO
IPC: B60S1/08
Filed: 1983-10-25
Abstract: PURPOSE:To prevent a wiper blade from being caught between a rear window and its window frame, by providing an inhibiting means for inhibiting the supply of electrical power from a d.c. power source to a second signal generating means irrespective of a delivered control signal. CONSTITUTION:When an ignition key is inserted into a key cylinder in the outside surface of the rear section of a sport wagon, and is manupulated to turn the bifurcated contact 41 of a window switch 40 onto an opening side stationary contact 42, a transistor 72 is energized by the power feed from a d.c. power source B through two resisters 72a, 72b, due to that a storing detecting switch 13 is closed, and therefore, a transistor 71 is sustained to be deenergized. Therefore, even if the window switch is manipulated to open a rear window, the electrode coil 91 of a relay 90 sustains its deenergizing condition since the transistor 71 cuts off power from the d.c. power source B to the coil 91. That is a rotary motor M2 is not allowed to receive power from the d.c. power source B through the bifurcated contact 92 and therefore is left to be stopped, thereby the above- mentioned rear window sustains its closed condition.
