Title: Sheet conveying device and image forming apparatus
Inventor: GOTO HIROSHI
IPC: B65H9/06
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To correct skewing of sheets of many sizes and thicknesses to attain stable conveying performance by providing a shutter member capable of oscillating to a first attitude of locking the leading edge of a sheet and to a second attitude, of passing a sheet. SOLUTION: In the case where a sheet with a width L1 or more skews, the sheet abuts against one of contact surfaces 12a, 12d, and then it does not abut against contact surfaces 12b, 12c of the central part. Accordingly, after it abuts against both of the contact surfaces 12a, 12d, a loop is formed to produce sliffness, thereby turing a shutter member 12 to take a second attitude. In the case where the width of a sheet is L2-L1, it abuts against only two contact surfaces 12b, 12c of the central part to form a loop, thereby turning the shutter member 12. Accordingly, in the case where the width is L2 or more, it always abuts against only two contact surfaces, thereby eliminating the possibility of turning the shutter before skewing is corrected.

Title: Ultrasonic flowmeter
Inventor: TASHIRO KOICHI
IPC: G01F1/32
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter that can be corrected in temperature and can be improved in measuring accuracy. SOLUTION: The ultrasonic flowmeter is provided with an arithmetic device 11, which finds the temperature of an ultrasonic sensor 5 by collating the measured data of an impedance measuring instrument 9 and a gain measuring instrument 12 with the data stored in a gain/frequency data storing circuit 13 and adjusts the frequency of a pulse impressed upon an ultrasonic transmitter 3 based on the temperature data. Since the sensor 5 fulfills the function of the conventional temperature sensor, no separate temperature sensor is required. Therefore, the measuring accuracy of the flowmeter can be improved, because the change in the flow of a fluid, which may occur when a temperature sensor is provided in a pipe 1 does not occur. Since the number of parts becomes smaller and no temperature sensor is required in the pipe 1, the structure of the flowmeter is simplified and, in its turn, the cost of the flowmeter can be reduced.

CONSTITUTION:When one pulse of the trigger pulse of phi1 is supplied to an input terminal phi1, it is successively delayed by invertors d-d, and the clock pulses are generated successively from the terminals C1-Cn in said order. When the clock pulse is generated from the terminals C1, the latching circuits L11, L21 go to ENABLE, and the data of the respective previous steps are fetched, and since this operation is carried forward successively by the clock pulse of the n-phase, the data are shifted by one step, in the respective shift registers SR1, SR2. Since the pulse generation circuit is constituted of the delay circuit and the gate circuit, the fewer number of the elements are enough, compared with a conventional device.

Title: Inclination sensor
Inventor: MURATA HIROSHI
IPC: G01C9/06
Filed: 1991-03-22
Abstract: PURPOSE:To detect the direction of an inclination and the inclining angle in the inclination direction by a single sensor, by detecting a magnetic field which is changed when a magnetic sphere is rolled and shifted on a concave curved face of a supporting body as a result of the inclination of the whole of the inclination sensor. CONSTITUTION:When the whole of a tilt angle sensor is inclined in any direction and a supporting body 1 is also inclined in the same direction, a magnetic sphere 2 is rolled on the spherical face of the supporting body 1, and inclined and shifted downward. The density of a magnetic flux passing through four magnetism detecting elements 3 is increased or decreased because of the shift of the magnetic sphere, and therefore detecting signals of the elements 3 are changed. In other words, the balance of the level of the detecting signals of the four elements 3 is changed in accordance with the displacement of the magnetic sphere 2. The direction of the displacement, i.e., the direction of the inclination of the magnetic sphere 2 can be known from the state of the change of the balance. Moreover, as the magnetic sphere 2 becomes farther from the lowest part of the supporting body 1, the level of the detecting signal of each element 3 is decreased. Therefore, the amount of the displacement of the magnetic sphere 2, namely, the inclining angle of the magnetic sphere 2 can be detected from the level of the detecting signal of the element 3.
