Title: High frequency oscillating type contactless switch
Inventor: NODERA HISATOSHI
IPC: H03K17/95
Filed: 1985-11-15
Abstract: PURPOSE:To detect the presence/absence of a disconnection in a detection coil with a high frequency oscillating type contactless switch composed of a DC bias circuit and the detection coil, which are connected in series, by detecting a DC bias voltage. CONSTITUTION:When a detection coil L1 is not disconnected, oscillating AC components around a voltage VB are overlayed around the base of a transistor Q3 one upon another, because the DC bias voltage of the transistor Q3 is the voltage component BB of a bias circuit 3. On the other hand, when the detection coil L1 is disconnected, no electric current flows to the bias circuit 3 and oscillation is stopped. Therefore, when the voltage shown on the B side of the figure is inputted to a detection circuit 9, the voltage exceeds a level discriminating value La. As a result, an integrated output, namely, the output (iii) of the detection circuit 9 rises to a prescribed value and is saturated and the output (iv) of a voltage discriminating circuit 10 becomes 'H' in level, and then, an 'H' level signal indicating a fault is outputted from a fault output circuit 11.

Title: Thermal head
Inventor: TSUMURA MAKOTO
IPC: B41J2/345
Filed: 1984-12-07
Abstract: PURPOSE:To enhance printing quality and to enable multi-gradation medium contrast recording, by controlling the shape of a heat generating resistor so as to continuously increase applying energy per a unit area. CONSTITUTION:The width of a heat generating resistor 8 is made finer as approaches the front surface of a thermal head in the ralative moving direction 9 to photographic paper and the region exceeding printing start temp. increases in the order of curves 10, 11, 12 as a pulse applying time increases. The region 13A of the heat generating resistor 8 is printed in a dot form shown by a printed dot 14A. Next, as the pulse applying time is increased, the printing region of the heat generating resistor 8 increases in the order of regions 13B, 13C but, because a printable region is magnified rearwardly with respect to the moving direction of the thermal head, the abrupt extension of the printed dot to the moving direction is not generated and the printed dot increases in its area while the shape thereof is kept almost circular. Therefore, by changing the pulse applying time, the area of the almost circular printed dot can be controlled and multi-gradation medium contrast recording of 16 gradations or more excellent in printing quality can be realized.

Title: Controller for photographing with flash by camera
Inventor: OMORI SHIGETO
IPC: G03B7/16
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To suitably photograph a photographic scene, where reflection from the background has a large influence, with a flash. SOLUTION: A CPU 1 calculates the magnification of image in accordance with the subject distance and the focal length detected by encoders 5 and 6 and sets the multi-division dimming control in the case of the magnification of image equal to or larger than a threshold (the practical dimming area of multi-division dimming is only the main object) and sets the FM control in the other case. A flash circuit 9 emits flash by a light emission start signal ST0 from the CPU 1. In the multi-sivision dimming control, a dimming circuit 7 divides reflected light from the object of the flash into plural dimming areas to receive it; and when the weighted average value of the quantity of reception light in each dimming area reaches a prescribed dimming level, a light emission stop signal ST1 is inputted to the flash circuit 9 to stop light emission.  In the FM control, the CPU 1 starts counting the light emission time simultaneously with light emission by a counter 101 and inputs the light emission stop signal ST2 to the flash circuit 9 to stop light emission at the time of the end of counting.

Title: Material for damping waterless planographic printing plate
Inventor: SUZUKI NORIHITO
IPC: G03F7/023
Filed: 1988-10-12
Abstract: PURPOSE:To obtain the material for a damping waterless planographic printing plate which decreases the fatigue of a developing soln. and with which the printing plate having a wide development latitude, excellent printing resistance and good reproducibility without having scumming is obtainable by incorporating resin components which are three-dimensionally crosslinked with each other into a photosensitive layer. CONSTITUTION:The damping waterless planographic printing plate is constituted by successively providing a photosensitive layer and a fluoroplastic layer on a base. Since the photosensitive layer contains the resin components which are three- dimensionally crosslinked with each other, the layer forms the bonds which are secure with each other. The insolubility in the developing soln. is thereby imparted to the photosensitive layer and the fatigue of the developing soln. is eventually decreased. Development by using solvents except, for example, a fluorine system as the developing soln. is possible. In addition, the development latitude when the development is made is widened. Further, the printing plate obtd. from this plate material has excellent plate wear and the excellent reproducibility of shadow parts and small dots without generating the scumming of the plate surface.

Filed: 1990-09-27
Abstract: PURPOSE:To determine the position of an underground excavator relative to a reference point on the real-time basis by receiving signals emitted from two signaling sources at three points of the excavator. CONSTITUTION:When a signal 18 emitted from a transmitter 14a reaches, signal receiving antennas 20a-20c installed on a cutter head 12 forward the received signal to receivers 24a-24c. The receivers 24a-24c pass a reception signal to a signal processing part 26. indicating that such a signal 18 has reached the antennas 201-20c. The signal processing part 26 determines thereupon the relative position of signal transmitter 14a to an underground excavator concerned 10. That is, the position of the transmitter 14a relative to the excavator 10 is obtained as a function of signal transfer speed V, wherein the distance L be tween transmitters 14a, 14b is known, so that the speed at which the signal 18 propagates under the ground can be determined. Which permits knowing the position S1 of the transmitter 14a relative to the excavator 10 or the posi tion S2 of the transmitter 14b. Because the transmitters 14a,14b are installed in a known position relative to the reference point, the position of excavator to this point can be determined.
