IPC: H01P1/22
Filed: 1988-06-30
Abstract: PURPOSE:To by easily built in a high frequency circuit and to execute a miniaturization of a device by arranging a signal absorber on a strip line substrate movably for each 1/4 wavelength and, simultaneously, in a direction right-angled to the signal direction of a strip line. CONSTITUTION:On one internal wall surface of a high frequency part case 1, a strip line substrate 2 is provided. A signal absorber 3 is arranged at the interval of 1/4 wavelength (lambda9/4) on the strip line substrate 2 by a holder 4 for it. The holder 4 is provided movably in the direction in which the signal absorber 3 is crossed to the signal direction on the strip line by means of a screw 5 fitted to the case 1.

Filed: 1982-09-16
Abstract: PURPOSE:To collect peripheral equipment information easily with high reliability by transmitting the selection signal for an input/output controller through a loop where plural input/output controllers are connected in series on farther- terminal return basis. CONSTITUTION:Pieces of information on peripheral equipments are sent out of a channel CH500 in the order of input/output controllers IOCs 610 and 620 starting with the nearest IOC 600. Then when a select-out signal SEO is outputted from the CH500 after information PE is sent out of a farther-terminal IOC630, FFs of all IOs are set, so the signal SEO is sent back from the farther terminal as a selection input signal SEB as it is. Further, the signal SEO is returned as a select-in signal SEI to the CH500 through logical circuits of respective IOCs. When the CH500 receives the signal SEI, the CH500 causes interruption to a CPU100 to complete the collection of the information PE.

Title: Display unit for braille display
Inventor: ONISHI MICHIHIRO
IPC: G09B21/00
Filed: 1992-06-19
Abstract: PURPOSE:To rewrite the braille display and to display braille in real time, and to manufacture the display unit at a low cost by a simple process by laminating a high molecular gel film on a substrate where electrodes or heaters are arranged. CONSTITUTION:The high molecular gel film 3 which thermally expands is laminated on the substrate 2 where the heaters 1 are arranged. For example, when a braille corresponding to 'o' in Japanese is displayed in an area A-B of the display unit for braille display, heaters 1a and 1b are turned ON and the remaining heaters are OFF. Consequently, the high molecular gel on the heaters 1a and 1b which are turned ON are raised to display the braille corresponding to 'o'. To erase the displayed character, the heaters 1a and 1b in the ON state are only turned OFF. The high molecular gel film 3 becomes flat at the raising part since the temperature falls to return to the non-display state. The high molecular gel used for the high molecular gel film 3 may be used only for swelling, shrinking, or hardening according to potential difference, current, or temperature variation.

Title: Switching system
Inventor: HENRII ESU KATSUTSUENSUTAIN
IPC: H03K17/60
Filed: 1988-07-01
Abstract: PURPOSE: To charge/discharge a capacitor within an accurate period by closing a 1st switching means and opening a 2nd switching means in response to a front edge of an input signal, and inversely operating the switching means in response to a tail end. CONSTITUTION: When a front edge of an input signal 44 is given to a base of a transistor(TR) 40, the TR is conductive and a voltage drop obtained across a resistor 46 makes a TR 24 nonconductive. Since a current via a winding 30 is interrupted, a pulse is induced, a negative pulse in a winding 28 makes a TR 18 nonconductive. A voltage pulse in the winding 26 makes a TR 16 conductive to charge a capacitor. When a tail end of an input signal 44 comes, the TR 40 is nonconductive and a TR 32 is conductive. A pulse generated in the winding 28 makes the TR 18 conductive and a pulse generated in the winding 26 makes the TR 18 conductive thereby discharging the capacitor.

Title: Flexure amount adjusting system for image forming device
Inventor: MORI HIROSHI
IPC: B65H9/14
Filed: 1990-06-22
Abstract: PURPOSE:To prevent a wrinkle from occurring by making the stop timing of a recording paper by a feeding control means earlier so that the flexure amount of an envelope may be smaller than that of an ordinary recording paper in the case that the fed recording paper in the envelope. CONSTITUTION:When the fed recording paper butts against a resist roller pair 5 and stops, flexure is generated between the resist roller pair 5 and a feeding roller 2 to correct obliquely advancing. Two timer values (ta) and (tb) are stored in a ROM 12 corresponding to the flexure so that the flexure amount of the envelope may be smaller than that of the ordinary recording paper in the case that the recording paper is the envelope. When the fed recording paper is the envelope and the counted value of an incorporated counter attains (ta), a paper feeding clutch 17 is turned off so as to stop the feed of the envelope. Thus, the smaller flexure is generated in the envelope than in the ordinary recording paper between the resist roller pair 5 and the feeding roller 2, that means, the optimum flexure owing to which the wrinkle does not occur is generated to correct the obliquely advancing.
