Title: Method for forming copper alloy layer on surface of ceramic
Inventor: SHINPO AKIHIRO
IPC: C04B37/02
Filed: 1994-09-16
Abstract: PURPOSE: To provide a method for forming a copper alloy layer having an easy processability on the surface of ceramics. CONSTITUTION: This method consists of applying paste layer of a powdery metalizing component of 5-20μm in thickness on the surface of ceramic, covering the metalizing layer with a copper alloy thin plate of 10-500μm in thickness, subjecting the product to a heat treatment to bind the copper alloy thin plate to the surface of the ceramic through a metalizing layer and forming a copper alloy layer having easy processability on the surface of the ceramic.  Another form of the method consists of applying paste layer of powdery metalizing component of 5-20μm in thickness on the surface of ceramic, coating the metalizing layer with a paste layer consisting of copper alloy powder of 10-500μm in thickness, subjecting the product to a heat treatment to convert the applied copper alloy powder paste layer to an easily processable copper alloy layer which is bound to the surface of the ceramic through the metalizing layer. The ceramic material having a copper alloy layer on the surface obtained by the method is easy in fine modifying processing of the surface because the copper alloy is excellent in processability. Further, it keeps the features of ceramics such as low thermal expansion, high stiffness and light weight because of thin thickness of copper alloy layer.

Title: Magnetic recording medium and its recording and reproducing method, and information processor using the same
Inventor: SEO YUZO
IPC: G11B5/82
Filed: 1993-10-01
Abstract: PURPOSE:To obtain an inexpensive writing device by recording a specific servo signal in a pigment containing layer which is suitable for optical signal writing. CONSTITUTION:Signals 21 and 22 are recorded at nearby different positions on the surface of the medium. The signals which are thus recorded nearby each other are mixed when reproduced, and outputted from a detector. The wavelength of the signal 22 is 1/2 as long as the waveform the signal 21 and recorded differently in phase from the signal 21, track by track. The signal that the detector 31 outputs when it is right above a track 2 (1st position) corresponds to the signal on the track. When the detector moves up to 2nd position, the signal of a track 3 is mixed with the detector signal and a short- wavelength component advances in phase. When the detector 31 moves down to a 3rd position, on the other hand, the signal of a track 1 is mixed with the detector signal and the short-wavelength component is delayed in phase. Consequently, the position of the detector is detected as a phase difference to perform accurate tracking.

Abstract: PURPOSE:To enable to make such a constitution as being free from misoperation because of no awaring of incoming by providing a timer circuit in a main device, and by designing not to make answer function of automatic selection of channel actuates in the preliminarily fixed time. CONSTITUTION:When the data is inputted in a telephone control circuit 41, an incoming is displayed by blinking a trunk line lamp 44 corresponding to the trunk line under incoming as well as audible display of the incoming by speaker 45. After that, in case of answering to the incoming by a key telephone 40, answering to the trunk line under incoming is available only by lifting a hand set and making a hook switch 42 after the preliminarily fixed time. In case that the hand set is lifted and the hook switch is made off hook in the fixed time set by timer circuit 35, the answering function of automatic selection of channel must not be actuated. Thus, such a problem as the incoming falls in answering and call condition and trunk line is broken against the incoming at a time when the operator pushes a trunk line button under reservations can be removed.

CONSTITUTION:When the destination cage call registration button 1B of the first floor is pushed and then pushed once again, a contact amplifying relay 1BX is turned on; a cage call cancelling timer 1T is turned on by a circuit of P-1B-1BXb-1Ca-1T-N before the relay 1BX is on, and the timer 1T is self- suspended by a circuit of P-1B-1Ta-1T-N so that as long as the cage call registrating button 1B is on the cage call cancelling timer 1T is on even when the contact 1BXb breaks the circuit next time. After a period of one minute elapses as the cage call registration button 1B is pushed, the cage call cancelling timer 1T completes time counting and opens its delay break contact 1Tb so that a cage call registration relay 1C releases self-suspension and is turned off to cancel registration of a cage call on the first floor.

Abstract: PURPOSE:To simplify a control means, by providing power sources for normal voltage and reverse voltage which are applied between a workpiece and an electrode by switching elements so that the averaged machining voltage is made to be zero. CONSTITUTION:Control is made such that a normal voltage E1 is applied between a workpiece W and an electrode P from an oscillator 2 for a predetermined period so as to allow a capacitor C1 to discharge several times for carrying out electric discharge machining, and thereafter, a reverse voltage E2 is applied between the workpiece W and the electrode P while the application time of the reverse voltage is controlled so that the application time of the normal voltage and the application time of the reverse voltage are made to be zero in average during one entire cycle. Accordingly, the control and the arrangement are simple in comparison with those of the conventional system in which a reverse voltage is applied for every discharge to make the averaged machining voltage zero, and therefore, it is possible to stabilize electrical discharge.

Title: Photosensitive material transport apparatus
Inventor: ARAI HARUHIKO
IPC: B65H23/035
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent a jam and meandering of a photosensitive material by setting the interval in the cross direction of transport guides a little larger than the width of the photosensitive material and reducing the interval in the cross direction of sub-scanning transport guides of an exposure part substantially to the measured maximum width of the photosensitive material at the time of starting auto-loading for the photosensitive material. SOLUTION: When a photosensitive material magazine 38 is installed in a photosensitive material feeding part 26 in an image recording apparatus, the cross-direction intervals of transport guides 44, 60, 66, and the cross-direction interval of a transport guide 104 are respectively set a little larger than the width of a photosensitive material A by a motor 46 and a motor 105. Thus, the photosensitive material A drawn out from the magazine 26 by a pair of draw-out rollers 40 is smoothly transported while being guided by transport guides 44, 60, 66 and 104. When the photosensitive material A is detected by a sensor 106 in an exposure part 32, however, the cross-direction interval of the transport guide 104 is set narrower to be substantially equal to the cross- direction length of the photosensitive material A so as to prevent meandering at the time of paper transport.
