Title: Serial wire dot printer
Inventor: SHIROTORI HIROSHI
IPC: B41J2/51
Filed: 1992-08-25
Abstract: PURPOSE:To reduce noise by using a prior art print head where 2 rows of wires are arranged in a staggering way when the noise is reduced by shifting print timing at every wire and improve print quality at the same time. CONSTITUTION:A print head is mounted on a carriage in such a manner that wire rows L and R at the tip of the print head are oblique with respect to the vertical direction by an angle theta which satisfies the following formula: tan theta<=a/(2.b). Here, the a represents 1/2 of a pitch between wires in the wire rows and the b represents an interval of the wire rows L and R. A counter output to be counted by an output of a print start timer which issues pulses at a constant cycle is decoded and driving of each wire is started in sequence. Two print control devices having the same structure constitution so as to stop driving of each wire in sequence are provided for the wire row L and the wire row R.

Title: Measuring apparatus
Inventor: TANO MASAHIRO
IPC: G01R15/24
Filed: 1984-10-26
Abstract: PURPOSE:To enhance measuring accuracy by removing noise, by generating timing signal corresponding to the predetermined change in a physical quantity to be measured and performing the polarity control of the signal outputted from a sensor part on the basis of said timing signal. CONSTITUTION:The output from a photoelectric converter 9 is respectively inputted to a DC amplifier, that is, a reference signal extraction part 10 and a synchronous detection circuit 24. Electromotive force is generated in the detection coil 19 provided to an iron core 16 in a state wound therearound by magnetic flux 6 changing corresponding to the change in the AC current flowing through a conductor 15. A light emitter 20 comes on and off corresponding to the electromotive force of the detection coil 19 and this ON-and-OFF is transmitted to a photoelectric converter 21 through an optical fiber 22 to generate a timing signal. A synchronism detection circuit 24 detects the output of the photoelectric converter 9 in synchronous relation to the timing signal and, if said signal is smoothed by a smoothing circuit 25 to take an average value, even number higher harmonics are negated to each other and the greater number of higher harmonics are mutually negated. Therefore, a detection signal is outputted by a sensor part 2 in the form of a DC signal.

Title: Piezoelectric transformer and manufacture thereof
Inventor: FUDA YOSHIAKI
IPC: H01L41/22
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric transformer having such a structure and manufacture thereof at a low cost that prevents electrodes from short-circuiting and migration of an electrode material to ensure a reliability for the long time use and prevents the electric shock due to contact to electrodes in the piezoelectric transformer manufacturing step or inverter assembling step. SOLUTION: Spurious strays occurring near a resonance frequency influence on a resonance phenomenon to lower the electromechanical coupling factor and efficiency of a piezoelectric transformer, resulting in a heating phenomenon, and hence a possibly light and thin paint film formed on the surface of this transformer is preferable. The thickness of a rectangular piezoelectric ceramic plate and that of a glass layer used to form an insulation film are investigated in terms of the piezoelectric transformer efficiency to find that the influence is remarkable when the glass layer thickness exceeds one-tenth of the rectangular plate thickness.

Title: Image forming device
Inventor: FUKUDA HARUHIKO
IPC: G03G15/00
Filed: 1992-08-03
Abstract: PURPOSE:To certainly prevent forgery by providing with a forgery preventing means limiting the copy-processing of a special original, a sensor means sensoring detaching from the image forming device of the forgery preventing means and a control means setting a copying function to be in an impossible state. CONSTITUTION:A system controller 106 judges whether the forgery preventing device 104 is connected within an image forming device or not by a signal from the sensor 105 and at the time of judging it to be connected, the controller 106 decides whether an original to be the object of copy is the special original such as paper money, etc., or not. At the time of judging it not to be the special original, the controller 106 executes a normal copy operation. At the time of judging it to be the special original such as paper money, a forgery preventing processing (the stoppage of a series of copy-processings or the working output of a part of image information) is executed. Besides, at the time of judging that the forgery preventing device 104 is detached from the main body of the image forming device from a signal from the sensor 105, the copying function is stopped and a service man call is executed. Consequently, the device is not recovered until a service man completes the resetting of the forgery preventing device 104.

Title: Rotational position detecting system for disk device
Inventor: AYADA KOJI
IPC: G11B27/10
Filed: 1987-09-12
Abstract: PURPOSE:To efficiently detect a rotational position by extending forward a subsequent sector coincidence signal for a prescribed time, in case the sector coincidence signal has not been received by a control part, exceeding the prescribed number of times. CONSTITUTION:A sunk counter 10 for counting the number of times by which sector coincidence signals 17a, 17b have not been received by a control part 3 is provided in interface control parts 4a, 4b. In case the value of the sunk counter 10 has exceeded a value determined in advance, the sector coincidence signals 17a, 17b are extended forward from a regular position for a prescribed time, and the detection probability of the sector coincidence signals 17a, 17b by the control part 3 is raised, by which sinking of the processing can be eliminated. Accordingly, it will suffice that the control part 3 adds only the processing for setting a threshold level to the sunk counter 10, and a smaller increase of the processing time than a system for monitoring the time of each disk device 2a, 2b is enough. In such a way, the rotational position of the disk device can be detected efficiently.

IPC: G11B5/60
Filed: 1993-09-13
Abstract: PURPOSE:To obtain a slider and a magnetic memory device which shows a superior speed characteristic in a floating height and a generally constant floating height at an optional position on a magnetic recording medium, restricts a change of the floating height due to a seek operation or dusts to be small and is suitably fitted to be of a low floating height to float stably.

A magnetic converter is mounted at the air outlet end. A curvature rho of the floating surface 4 is set to hold 0<rho<0.08 (1/m). Even when the peripheral velocity of a magnetic recording medium changes, the load capacity of the slider hardly changes. Therefore, even the slider of a type utilizing a positive pressure has a generally constant floating height at any position of the magnetic recording medium.

Title: Shaft connecting structure
Inventor: INUI MASAKI
IPC: B60K17/35
Filed: 1986-09-26
Abstract: PURPOSE:To smoothly insert a shaft member by providing a valve element for letting air in the inside of an insertion hole escape at the time of inserting the shaft member to prevent the internal pressure in the insertion hole from increasing. CONSTITUTION:After the completion of assembling internal parts, a front wheel output shaft 9 is inserted in an insertion hole 24 to be spline-fitted. In that case, the internal pressure in the insertion hole 24 is increased the moment an O-ring 41 enters the insertion hole 24. As the result, a lip portion 40 of an oil seal 36 disposed between a plug 35 and the inner peripheral surface of the insertion hole 24 is sagged to form a gap, so that air is let out of the insertion hole 24 into a chain room 14 through a slit portion 39. Accordingly, the internal pressure in the insertion hole 24 is held down less than a fixed pressure, so that the front wheel output shaft 9 can be smoothly inserted.
