Title: Ink jet recording device
Inventor: SATO MASUMI
IPC: B65H5/00
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To stabilize paper sheet conveyance by dotting insulators on the surface of a conductive belt to constitute a conveyor belt for conveying a paper sheet. SOLUTION: A paper sheet is fed from a paper sheet feeding cassette to a conveyor belt 23, and bias voltage of about 100-1000 V is applied to a carrier roller to electrostatically attract the paper sheet. The conveyor belt 23 is constituted by dotting insulators 23b on the surface side of a conductive belt 23a, and the electrostatic microfield is generated by applying bias voltage to attract the paper sheet electrostatically. The paper sheet is therefore conveyed in the state of being positively electrostatically attracted to the conveyor belt 23, and ink drops are discharged from a recording head to record an image on the paper sheet. Since the paper sheet is positively attracted to the conveyor belt 23, waving is not generated even in the state of the tip and rear end of the paper sheet not being nipped by the carrier rollers.  As a result, the printable area of the paper sheet is enlarged, and paper sheet conveyance is stabilized.

Title: Control circuit for electric water heater
Inventor: OOSHIO SEIJI
IPC: F24H1/18
Filed: 1984-06-27
Abstract: PURPOSE:To obtain good economical property without using useless daytime electric power by permitting conduction of an electric heater for a given time in daytime. CONSTITUTION:A daytime electric heater control circuit 17 opens and closes a relay 18 only while a timer circuit 16 is operating a timer operation. The relay 18 is kept in the opened condition thereof while the timer operation is being stopped and midnight electric power is being detected by a midnight electric power detecting circuit 10. A night electric heater control circuit 19 opens and closes the relay 20 while the midnight electric power is being detected by the midnight electric power detecting circuit 10. The relay 20 holds the opened condition while the midnight electric power is being stopped. The time-up of a timer circuit 16 is caused at 5 o'clock in the afternoon, for example, and timer stopping signal is outputted. The daytime electric heater control circuit 17 holds the opened condition of the relay 18 by said signal and stops the conduction of a daytime electric heater 5. According to this method, the useless daytime electric power may be saved.

Title: Still picture transmitting method and reproducing method
Inventor: ANDO ICHIRO
IPC: H04N19/33
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a still picture transmitting method and reproducing method, by which a still picture reproducing time required in an early stage is shortened in addition to the suppression of deterioration in transmission efficiency. SOLUTION: Still picture encoding circuits 2 and 3 encode same input still picture data by different encoding characteristics, obtain still picture encoding data D1 and D2 and stores them in encoding data memories 4-1 and 5-1. Encoding data read from the memories 4-1 and 5-1 are multiplexed with various kinds of identifying information and another kind of encoding data by a prescribed repetition frequency by multiplexing circuit 6 and, then, outputted to a transmission line by way of a transmission line circuit 8. Still picture encoding data D1 with a small encoding amount is repeatedly transmitted by the frequency being higher than that of still picture encoding data D2 with the larger encoding amount. Then the deterioration of transmission efficiency is suppressed and also the still picture reproducing time required in the early stage is shortened.

Title: Magnetic tape device
Inventor: MORIMOTO TAKAO
IPC: G11B25/06
Filed: 1988-05-30
Abstract: PURPOSE:To correctly read a head signal and to cause a magnetic tape device to be suitable for vehicle mounting by absorbing the difference of expansion and contraction quantity in a guide board surface direction based on the difference of a thermal expansion coefficient between the supporting stand of a mounting means, which constitutes the tape device, and a guide board and causing the inclination of the revolving surface of a magnetic head and the guide board to be constant to a temperature change. CONSTITUTION:A magnetic tape 15 is led out of a cassette case, which is not shown in a figure, by guide rods 14a-14d and guide rod supporting bodies 16a and 16b are respectively moved along guide holes 17a and 17b. Then, for the tape 15, a magnetic head 10 is abutted to a revolving drum 9 and a fixed drum 11. In such a condition, when a surrounding temperature is changed, any change is not generated in mounting parts 17c and 19a since they are mutually fixed and mounted. However, in mounting parts 17d and 19b, since the thermal expansion coefficient of a supporting body 19 is larger than that of the guide board 17, the mounting parts 17d and 19b are moved only by the portion of thermal expansion. Accordingly, a fitting angle theta for the revolving surface of the head 10 and the guide part 17 is not changed even when the temperature rises up or falls down. Thus, the exact recording or reproducing of the signal can be executed.

Abstract: PURPOSE:To make it possible to overlap a wide domain of transmission image and a minute probe irradiation image, and to observe the both images simultaneously, by controlling the focus distance of a focus lens. CONSTITUTION:The focus distance is controlled to obtain a wide domain image and a minute image alternately for a time shorter than the afterglow time of a fluorescent screen where the image is focused. By the control voltage depending on a signal (a) for a focus lens, focus distances for the wide domain image and for the minute image are formed alternately, and the wide domain transmission image and the probe image in a minute domain are overlapped and observed. At the starting and the ending of the focus lens magnetic field variation (b), the beams are taken off from the fluorescent screen by a signal (c) for a focus lens deflecting coil. The minute probe image is exposed on a film during the observation by a signal (d) for an intermediate lens and a signal (e) for a projection lens deflecting coil.

Filed: 1987-05-30
Abstract: PURPOSE:To detecting respective components of a composite load on a composite load application part without being interference by other components by combining the number, positions, angles, and electric outputs of strain gauges SG stuck on an elastic body. CONSTITUTION:Up to two SGs 2 (21-28) are stuck on the center part of each of four flanks of the elastic body 1 of a load cell, i.e., by eight in totals so that they cross each other at 45 deg. to the axis Z. Then, those SGs 2 are combined according to a load to be detected to constitute a bridge circuit as usual, and while a terminal Eex is connected to a power source, a terminal Eout is connected to an output side. Then the way of connecting the SGs 2 is changed properly according to the load to be detected so that, for example, a figure (a) shows a combination for detecting a Z-axial load PZ and a figure (b) shows a combination for detecting bending moment BX-Z in an X-Z plane. Consequently, when the load is placed on the load cell, respective components, i.e. the load PZ, shear loads Sx and Sy, moment values BX-Z and BY-Z, and torsional moment TZ of the composite load are detected without being interfered by other components.
