Title: Output device for push-button number
Inventor: NAGANO SUKEATSU
IPC: G06F9/00
Filed: 1986-08-21
Abstract: PURPOSE:To prevent the malfunctions of push-buttons due to the variance of resetting characteristics of a relay even when another push-button is pushed as soon as the push of a certain push-button is released. CONSTITUTION:When a push-button is depressed, the contacts 1aa, 1ba...1ja set at one side of a 1st contact group 1A are closed in response to said push- button. At the same time, the contacts 1ab, 1bb...1jb set at the other side of a 2nd contact group 1B are opened in response to closure of contacts 1aa...1ja. Thus a setting part S works with each of self-holding relays 5a...5e and the relay contacts 6a...6e of a code output circuit 6 are opened. Then a code having the prescribed weight is delivered to a computer 2. When the push of said push-button is released, the contacts 1aa...1ja of the group 1A are opened together with the contacts 1ab...1jb closed respectively. As a result, the relays 5a...5e are forcibly cut off and output of the code is discontinued to the computer 2 from the circuit 6.

Title: Bottom die of finishing die for forming glass product
Inventor: YAMAMOTO YASUHIRO
IPC: C03B9/335
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To provide the subject bottom die for foot pressing of glass products, which prevents biting of a parison, thereby decreasing defective products and increasing product yield. SOLUTION: This bottom die is provided with a guide ring 4 which can move freely in the vertical direction to project out of the upper surface 1 of the bottom die and retreat to have its upper surface aligned at the upper surface 1 of the bottom die. The guide ring 4 projects out of the upper surface 1, when the bottom die is open to receive a parison P, in order to check expansion of the parison bottom. Its upper surface is aligned at the upper surface 1 of the bottom die, when the bottom die is closed. When parison P hangs down by gravity to contact the bottom die, the guide ring 4 projecting out of the bottom die checks lateral expansion of the parison bottom to prevent biting of the parison P. The guide ring 4 retreats to have its upper surface aligned at the upper surface 1 of the bottom die, when the bottom die is closed, and provides no obstacle to forming glass products.

Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To obtain the titled recording medium with no deterioration of printing density after storage for a long time and excellent visual recognition by making rate of change in the printing density after NH3 exposure test of a reversible heat- sensitive recording material to at most a specified value. SOLUTION: A reversible heat-sensitive recording medium is prepd. by providing an aluminum reflective layer 12, a heat-sensitive layer 13 wherein a resin matrix and an org. low mol.wt. substance dispersed in the resin matrix are main ingredients and whose transparency changes reversibly depending on temp. and a protective layer 14 on a substrate 11.

Title: Picture reader
Inventor: SAKAMOTO TAKU
IPC: H04N1/409
Filed: 1990-07-25
Abstract: PURPOSE:To suppress granularity at an output by using a 3-color component such as a signal including R, G, B component as a signal of a noted picture element and surrounding picture elements for contour emphasis. CONSTITUTION:An output SW (W component sharp signal as to noted picture element) of a photoelectric conversion element 44 is given to a noninverting input of an adder 64 and an output UW (-unsharp signal as to surrounding picture elements) of a photoelectric conversion element 62 is given to an inverting input. Thus, a contour emphasis signal DT is obtained from the adder 64. Since the output signal SW including R, G, B components is used as each signal of noted picture element and surrounding picture elements, the granularity of each coloring layer of an original 6 is cancelled and the granularity caused in the output signal SW is reduced. Thus, contour emphasis is applied effectively to a required part without much emphasizing the granularity of the original 6.

Title: Erase device of video tape recorder
Inventor: YAMAZAKI MASANORI
IPC: G11B27/02
Filed: 1982-11-08
Abstract: PURPOSE:To apply always stable servo by dividing a full-width erase head into two sections, an video erase head section and control erase head section, and making an arrangement that the operation of the control erase head section is stopped especially at the time of electronic editing. CONSTITUTION:When the operation mode of a video tape recorder is switched to the electronic editing mode on the way of normal reproduction mode, a transistor 6 is set to the ON condition and a driving current is flowed to a relay coil 2b and, therefore, a control erase head section 1b is set to an isolated condition. Therefore, old video signals previously recorded on the video track of a magnetic tape are erased and new video signals are recorded on the track by means of a rotary head. However, control signals previously remaining on a control track are kept under the same condition. Therefore, control signals reproduced by a control head can always obtain stable servo operation irrespectively of the joint. As a result, high quality pictures which are not disturbed can be reproduced.
