Title: Recording speed discriminating system
Inventor: YOSHIDA RITSUO
IPC: G11B15/467
Filed: 1984-12-24
Abstract: PURPOSE:To exactly discriminate a recording speed by detecting at least one of difference frequencies. CONSTITUTION:In case the reproduction is performed in LP mode from the tape recorded in SP mode, a difference frequency of frequency 2fH is detected. The waveform of this signal varies depending on the phase relation between the magnetic tape and the heads 21 and 22, and on the widths of the said heads 21 and 22. This signal is detected at a period 4-times that of a head switching pulse Ps. The signal is detected of its level by a detecting circuit 42, and applied waveform shaping by a Schmitt trigger circuit 43 to obtain a square wave. If the reproduction is in SP mode from a tape recorded in LP mode, the difference frequency of frequency 2fH is detected at a period twice that of the head switching pulse Ps, and the outputs of the level detection and the waveform shaping are obtained. A deciding circuit 44 decides whether or not the recording speed and the reproducing speed coincide with each other by monitoring the occurrance of output level change of the Schmitt trigger circuit 43.

Title: Current waveform shaping circuit
Inventor: RINKA HIROYUKI
IPC: G05F3/26
Filed: 1992-10-12
Abstract: PURPOSE:To reduce counter electromotive force by controlling a current flowing to a coil load so as to lower the voltage of a circuit. CONSTITUTION:By constituting a first current mirror of transistors 5 and 6, connecting the secondary side to the primary side of a second current mirror composed of the transistors 7 and 8 and further connecting the secondary side of the second current mirror to the transistor 10, the currents flowing to the transistors 5 and 10 and the fluctuation amount of the voltage between a base and an emitter are made equal. A biased current is supplied from a constant current source 11 to the transistor 9 and the voltage between the base and the emitter is held fixed. Thus, even when the current flowing to a resistor 4 fluctuates by the fluctuation of an input pulse current, the electric potential of the collector of the transistor 5 is held fixed at all times, the time constant of the current flowing to the resistor 4 is decided only by the value of the resistor 4 and a capacity 3 and the counter electromotive force generated at the both ends of the coil load when the coil load is connected to a current output terminal 13 can be reduced.

Title: Ribbon feeding and changing mechanism
Inventor: YAEGASHI MORIMASA
IPC: B41J35/18
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent a malfunction in ribbon change by a method wherein change of a ribbon and feed of the ribbon are carried out with one motor, and transmission of rotation to a change gear in feed of the ribbon is stopped. SOLUTION: In change of a ribbon, a positive cam 3 is reversely rotated via a gear 2 and a one way clutch when a gear 1 is reversely rotated with a motor 9, a positive cam follower 4 holding a ribbon cassette is slid by action of the cam, and the ribbon is changed. In feed of the ribbon, the gear 1 is rotated in a formed direction. Though the forward directional rotation is transmitted to the gear 2 also, it is not transmitted to the positive cam 3 because of the one way clutch. In rotation in the forward direction, a detent pin 5 provided to the positive cam 3 is engaged with a detent groove provided to a positive cam follower 4, and a malfunction in change of the ribbon by motion of the positive cam influenced by idling torque of the one way clutch is prevented from being generated.

Filed: 1987-10-30
Abstract: PURPOSE:To make a sheet foldable in an optional position as specified, by moving and adjusting a folding position regulating stopper of a folding means according to the data of a folding position designated by a coordinate input means. CONSTITUTION:When a folding position for a Z fold or a half fold is designated to an original on original block glass 101 by a read pen switch on a pressure plate 300 with a digitizer, paper folding device 400 moves each of stoppers 404, 406 up to each corresponding position by stepping motors 402, 407 according to the designation. Then, a recorded sheet to be discharged out of a body 100 is entered into a pass 403 by a flapper 401, and at the time of the Z fold, when its tip hits on the stopper 404, it is folded into one fourth or so at a roller 408, then it is entered into a pass 405, and when hitting on the stopper 406, it is folded into about one half. On the other hand, at the time of a half fold, it is folded into one half or so at the pass 403, and passes through a roller 409 as it is, thus it is fed to a finisher 500. Thus, paper folding can be done at an optional position.

Title: Production of aluminum base for printing plate
Inventor: NISHINO ATSUO
IPC: C25F3/04
Filed: 1987-10-30
Abstract: PURPOSE:To obtain satisfactory printing performance and plate wear characteristics, by repeatedly subjecting an aluminum plate to an electrolytic graining treatment in a nitric acid-containing acidic electrolytic liquid, with an etching treatment between one run and the next of the graining treatment. CONSTITUTION:An aluminum plate is subjected to an electrolytic graining treatment in a nitric acid-containig electrolytic liquid by use of an AC current waveform, and then a treatment for dissolving edge parts of pits formed by the graining treatment is conducted. After the edged surfaces are made smoother, the electrolytic graining treatment is again conducted in a nitric acid- containing electrolytic liquid by use of an AC current waveform. This process is repeated, whereby minute, round and uniform honeycomb-shaped pits corresponding to the conditions of the latter electrolytic treatment are formed on the grain with a large-pitch waviness generated by the former electrolytic graining treatment. By a combination of the conditions of both of the electrolytic graining treatments, it is possible to easily produce a grain having a double pit structure with an arbitrary depth.

IPC: B23P11/00
Filed: 1987-10-29
Abstract: PURPOSE:To stick a plurality of flat boards highly accurately without producing foam by facing the flat boards through spacers, when flat boards such as liquid crystal panels are stuck, then bending the central section thereof through applica tion of load and contacting thereafter removing spacers from the opposite ends. CONSTITUTION:Flat boards 11 are faced each other with high accuracy then spacers 12 are inserted at the opposite ends. Then the flat board 11 is secured together with the spacers 12 through holding force. Furthermore, a load 14 is applied onto the central section of the flat board 11 to bend the flat board 11 so as to contact the flat boards 11 each other. Thereafter, holding force 13 is released and the spacers 12 are removed thus providing stuck flat boards 11. Since the flat boards 11 are contacting each other through the load 13, initial accuracy can be maintained when the spacers 12 are removed through friction force.
