Title: Control signal reproducing circuit
Inventor: ANDO HISASUMI
IPC: G11B15/467
Filed: 1985-12-18
Abstract: PURPOSE:To prevent the increase in the level of a reproducing CTL signal broader than the usual reproduction, to eliminate the erroneous detection and omission at the time of discriminating the amplitude and to execute the highly accurate detection at the time of quick feeding/rewinding or queue/review by providing a control circuit to generate a gain switching signal corresponding to the change of the actual tape speed while a speed change reproducing mode signal is received. CONSTITUTION:At the time of the quick feeding/rewinding or the queue/review, a timing controller 10, based upon these mode signals, generates a control signal S to change the gain of an operational amplifier 4 and an (f) characteristic, a switch 7 is closed and a resistance 6 is applied in parallel as a feedback resistance. For such a reason, since the gain of the operational amplifier 4 is reduced to about 1/3, the reproducing CTL signal of the approximately same gain as the time of the usual reproduction is derived from the operational amplifier 4 and at a slicing circuit 12, in the approximately same amplitude point as the time of the usual reproduction, the amplitude discrimination is executed, the erroneous detecting of a noise and the omission of a CTL signal are not increased and the correct detection can be executed.

Title: Pilot tracking system
Inventor: SAITO ISAO
IPC: G11B15/467
Filed: 1990-10-23
Abstract: PURPOSE:To facilitate accurate tracking by a method wherein different frequencies are given to pilot signals (PS's) of respective tracks so as to avoid mutual interference between respective recording heads. CONSTITUTION:The output of a first AND gate circuit 13a is supplied to a recording video head 1A through an adder 14a and a recording amplifier 15a as a TPS (tracking pilot signal) having a frequency f1 with a video signal VSig1 so as to be recorded by frequency multiplex recording. In the same way, the output of a second AND gate circuit 13b is supplied to a recording video head 1B as a TPS having a frequency f2 with a video signal VSig2 to be recorded by frequency multiplex recording. Then, while the TPS having the frequency f1 is recorded on a tape 5 by the head 1A, the TPS having the frequency f2 is not supplied to the head 1B and, on the other hand, while the TPS having the frequency f2 is recorded on the track of the channel of the tape 5 by the head 1B, the TPS having the frequency f1 is not supplied to the head 1A, so that the TPS's having f1 and f2 are intermittently recorded in one channel. With this constitution, an accurate pilot tracking system can be achieved.

Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To simplify the process, to reduce the manufacturing time, and to reduce the cost by drawing a sheet of a raw material to form a formed article body part including a rigid wall in manufacturing a formed article having a deep holed wall part in the vicinity of a side wall. SOLUTION: A formed article body part 10 which is formed by drawing a sheet is pressed in the vicinity of a cylindrical side wall 11 to form a deep hole 21. Because a deep holed wall part 20 is pressed, the depth (d) of the deep hole 21 can be secured by making use of the excessive wall thickness, and the cylindrical side wall 11 can be formed only by the drawing though the depth (d) of the deep hole 21 is larger than the thickness (t) of the cylindrical side wall 11, and the mechanical grinding for the cylindrical side wall 11 can be dispensed with. Then, the punching is performed to remove unnecessary parts 45, 46. In addition, a female screw is formed by the trimming of an unnecessary part 47 and the tapping to the inner surface of the deep hole 21 to obtain a targeted article A with the deep hole 21 as a female screw hole.

IPC: G03B27/58
Filed: 1986-12-01
Abstract: PURPOSE:To obtain a mask device which handles an edged image and an edgeless image by providing a couple of moving tables which are arranged movably in the breadthwise direction of a photosensitive material and auxiliary masks which are mounted on those moving tables and move forth and back slightly corresponding to the edged image and edgeless image. CONSTITUTION:This mask device has the couple of moving tables 112 and 114 which are arranged in the breadthwise direction of the photosensitive material 10 and the auxiliary masks 82, 84, and 86 which are mounted on those moving tables 112 and 114 and move forth and back corresponding to the edgeless image and edged image. Consequently, when the moving tables 112 and 114 are moved to a place where the size of a printed image is determined, the auxiliary masks 82, 84, and 86 are moved forth and back to and away from the moving bodies 112 and 114 to determine a printing range distinctively between the edge and edgeless images. A parallel moving mechanism is interposed between the breadthwise masks 84 and 86 and then the moving tables 112 and 114 are moved while their end parts held parallel to the lengthwise axis of the photosensitive material.

Title: Plate cylinder device
Inventor: ASADA KEISUKE
IPC: B41L13/04
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a plate cylinder device making it possible to print promptly an image of uniform density in the whole even when printing is conducted, with a fresh stencil master wound, after an apparatus is left unused for a long time, by preventing evaporation of ink effectively. SOLUTION: An ink cover 41 inside a plate cylinder is left in contact with the inner peripheral surface 6i of the plate cylinder 6 even when a printing apparatus is left unused for a long time. Thereby ink 42 sticking on the inner peripheral surface 6i is not put in an open state to the air and evaporation of the ink and consequent denaturization thereof can be prevented. Besides, it is possible to prevent occurrence of a large amount of spoilage in an incomplete printed state, at the restart of printing, until an image of uniform density in the whole is printed on printing paper, and an excellent printing state can be obtained promptly. By positioning the ink cover 41 at a detached position on the occasion of printing, a rotating motion of the plate cylinder 6 is not hindered and execution of high-speed printing is enabled.

Abstract: PURPOSE:To increase a key input speed by dividing characters and marks into plural groups, and displaying the names of the groups. CONSTITUTION:A code corresponding to a character key inputted from an input part 2 is stored at a character string buffer 4 in an inputting sequence. A character string decision part 5 decides whether the code stored at the character string buffer 4 is a numeric code or a character code, and sends a result to a control part 1. A code conversion part 6, when all of the codes stored at the character string buffer 4 are the numeric codes, converts them to mark codes, such as characters and marks, etc., corresponding to said numeric codes. At a mark dictionary 7, the name of the group and the character and the mark, etc., belonging to said group name are stored respectively in a form of the mark code. A dictionary read part 8, when all of the codes stored at the character string buffer 4 are character codes, reads the character and the mark, etc., belonging to said group from the mark dictionary 7 based on the group name represented by a string consisting of said character code and outputs.
