Title: Sheet feeding device of copying machine etc.
Inventor: NISHINO FUMIO
IPC: B65H7/18
Filed: 1981-02-19
Abstract: PURPOSE:To simplify the timing control of sheets of paper to be fed by such a construction that inverse one-way clutches are interposed between the sheet feeding means, resist means and their respective drive means and that drive of the feeding and resist means is changed over by direction switching of the drive motor. CONSTITUTION:Regular rotation of a sheet feeding motor M will turn the driving gear 33 in the direction for feed of sheets and put a one-way clutch 19 into coupling to rotate the sheet feeding roller 6 in the direction to feed the sheets. At this time, the resist under roller driving gear 22 rotates in the direction to disengage the resisting one-way clutch 20, so that the resist roller 7 remains at a stand-still. Thereby the sheets are seeped and put in alignment in the axial direction of the photosensing drum. Then reverse rotation of the motor M will stop the feed roller 6 and drive the resist roller 7 to feed the sheet. This arrangement does not require any complicated structures to obtain a secure and easy timing of the feed roller with respect to the resist roller.

Title: Fluid control valve control method
Inventor: OZAKI YUKINORI
IPC: H02P8/12
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption of driving means and the capacity of a battery power source by making the value of driving voltage and pulse output frequency of the driving means different according to opening action time and closing action time of a valve part for opening/closing a passage. SOLUTION: A valve part 11 built in a gas meter is normally in a opened state, and the flow rate is measured. On the basis of the measured value, an arithmetic processing part 14 integrates the flow rate and judges abnormality in case of the flow rate integrated value being larger than the integrated flow rate set value stored in the arithmetic processing part 14, and a valve closing signal is outputted from the arithmetic processing part 14. Voltage A and pulse output frequency A are applied to a stepping motor 12 from a driving circuit 15 to close the valve part 11. At the time of valve opening action, unless there is abnormality on the instrument side, a valve opening signal is outputted from the arithmetic processing part 14, and voltage B and pulse output frequency B are applied to the stepping motor 12 from the driving circuit 15 to open the valve part 11.  Driving voltage and pulse frequency are thus changed according to valve opening action and valve closing action so as to reduce power consumption.

Title: Production of surface relief type hologram
Inventor: AMAKO ATSUSHI
IPC: G02B5/30
Filed: 1987-02-04
Abstract: PURPOSE:To copy a hologram approximate to a designed duty ratio by forming nickel and a metallic thin film, which can be selectively etched, on a resist pattern and plating this resist pattern with nickel to obtain a nickel stamper. CONSTITUTION:A resist pattern 3 is formed on a glass substrate 1, and Ni and a metal which can be selectively etched such as Au are used to form an Au film 13, and plating is performed with the Au film 13 as a cathode to from an inverted pattern 6 consisting of Ni. The Au film 13 is dissolved after removal of a photoresist 2 to form an Ni stamper 14. Ultraviolet rays are projected after a photopolymer is injected, and it is peeled after curing to form a hologram 15. Since recessed parts 16 of the stamper 14 formed in this manner are wide, expanding deformation due to internal strain of nickel plating and narrowing of edges 4 of a grating due to contraction of the photopolymer are compensated in the hologram formed with this stamper, and a value approximate to the duty ratio of the resist pattern 3 is obtained.

Title: Phase synchronizing circuit
Inventor: YANO SHOICHIRO
IPC: H03L7/10
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To maintain synchronism, when a reference input signal is interrupted through incorporating a simple circuit by switching a VCO input terminal to a Vref, interrupting the loop connection and holding a VCO output frequency at a prescribed value, when a reference input signal is abnormal. SOLUTION: A PLL circuit compares the phases of input/output clocks by PC1, converts a result into a voltage, smoothes it, controls the output frequency of a VCO 3, divides a frequency by a frequency divider and synchronizes the input clock which is a reference input signal with the output clock. The amplitude and the frequency of a reference input signal f0 are monitored by a DET 9. If a monitoring result is normal, the connection of SW 12 is set to the output side of LPF 2. On the other hand, if the monitoring result is abnormal, the connection of SW 12 is set to Vref 13. When the reference input signal f0 becomes abnormal, the loop of the PLL circuit is interrupted, and Vref 13 is connected to the input terminal of VCO 3, and the output frequency of VCO 3 is held at a prescribed value by the voltage of Vref 13.

CONSTITUTION:The compressed air, which is sent from a compressor through an air supply pipe 25, passes through a gap 24, air feed holes 20, 15, and constricted portions 22, 16, and jets into gaps such as one between a journal bearing 19 and a hollow shaft 29 forming a shaft 28 and one between a thrust bearing 35 and an impeller 2. Thus the hollow shaft 29 is floated from the journal bearing 19, and the impeller 2 is separated from the thrust bearing 35, and the shaft 28 is supported to be freely rotatable. Part of the compressed air, passing through cooling holes 33, 34 formed at both ends of the hollow shaft 29, flows into the hollow section 31, and then is discharged to an exhaust groove 26 through a cooling hole 32. In this way, the shaft 28 is efficiently cooled to restrain the thermal expansion and the gap between the shaft 28 and the journal bearing 19 is properly maintained.

See-through cloisonne glaze is applied between these silver wires 2, followed by firing, whereby the cloisonne part 3 is formed. After the firing, the top surface of the closionne part 3 is polished. Only the bottom part of this ware body 1 having the cloisonne part 3 is dipped in a nitric acid solution or the entire part of the ware body 1 is dipped in the nitric acid solution. In this way, only the un-dipped portion or cloisonne part 3 is left. Thereby, the cloisonne part 3 is so formed that its top and bottom faces may be seen through. This is fitted to the through-hole part 6 of the handle 5 or other of the dinner ware through or not throgh a metal frame 7 by using adhesive agents.

Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To facilitate dimension control for a thread so as to lower manufacturing coat by forming an external thread part basically in a simple process similar to a conventional one. SOLUTION: In a cold forming tap, a projection part, 20', which is a part of the projection parts 20, 20' and is adjacent in the axial direction, is removed to a root, and a cutting blade 24, whose diameter dimension is matched with the inside diameter of an internal thread to be formed, is formed in the part equivalent to the removed root.  Therefore, in production of the cold forming tap, a maximum diameter of the root is not formed in a relief part 22 leading to the projection parts 20, 20', but the uneven shapes of the crest and the root are synchronized with each other in the circumference direction, so that crests and roots in the external thread can be efficiently formed at the same time with high precision in a thread cutting process in which a thread is cut by means of a grinding wheel formed on the outer circumference, and as a result, dimension control of the external thread part is greatly facilitated and a cold forming tap with high precision can be produced easily at a low cost.
