Title: Sliding door
Inventor: OKONOGI TAKAO
IPC: E05F15/10
Filed: 1993-09-06
Abstract: PURPOSE:To improve outward appearance without being looked at directly by dividing a door indoor side trim above and below into two parts, disloacting an upper part of a lower trim to the outdoor side, creating a space in the thickness direction between the upper part of the lower trim and a lower part of an upper trim, and arranging a rail and a holder. CONSTITUTION:The lower end of an upper trim 2 terminates on the lower indoor side of a sliding rail 4 fixed to the door side, and the upper end of a lower trim 3 terminates on the central part outdoor side of a holder 5 fitted to the sliding rail 4. The upper end of the lower trim 3 creates a large circular arc part 11 so as to avoid the holder 5, and is separated to the outdoor side from the lower end of the upper trim 2, and creates a sufficient space 12 to house the holder 5 between both. Though the circular arc part 11 of the lower trim 3 is opened to the indoor side, this opening part 13 is closed by an arm cover 8 when a door is closed. Since constitution to situate the upper end of the lower arm 3 on the outdoor side is adopted, the division of the trims 2 and 3 and the arrangement of the holder 5 and the sliding rail 4 in the divided part space 12 become possible.

Title: Receiver with gain calibration function
Inventor: OTSUKA TOSHIMASA
IPC: H03G3/20
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain a constant gain over an entire range of received frequencies without being affected by a secular change or a replaced module. SOLUTION: A control section 5 controls a calibration signal generating section 6 to output a calibration signal with a prescribed level over the entire range of received frequencies to an RF reception section 2 in a gain calibration mode. An A/D converter section 4 A/D converts a level of a calibration signal outputted from the RF reception section 2 via an IF amplifier section 3 and the control section 5 receives the result. The control section 5 varies an attenuator 2b of the RF reception section so that a difference between the level of the calibration signal and a level after A/D conversion falls within a prescribed level range and stores its setting value into a storage section 5a as gain calibration data.  In the case of a normal mode, the gain calibration data corresponding to a selected reception frequency are read from the storage section 5a to set an attenuation of the atennuator 2b of the RF reception section 2. Thus, the RF reception section 2 can obtain a constant gain for all the reception frequencies.

Title: Display device
Inventor: MARUNO MOTOSHI
IPC: G02F1/1333
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To provide the display device which prevents a light leak current without increasing processes and lowering performance. SOLUTION: On a glass substrate 1, a thin film transistor 27 for display, a pixel electrode 25, and a thin film transistor 28 for photodetection which senses light input are arranged in matrix. The thin film transistor 27 for display is formed across an amorphous silicon film 3 and an insulating film 5. The thin film transistor 28 for photodetection has an amorphous silicon film 3, so the intensity of the light of a light pen may be about 1/10 as large as that of the case wherein polycrystalline silicon is used.  The active layer of the thin film transistor 27 for display is formed of polycrystalline silicon, so the light from the light pen which is made incident from the side of a glass substrate 1 can be suppressed with the amorphous silicon film 3 of about 1 in OD1 (replacing transmissivity appearing in OD(optical density) with means of transmissivity in wavelength range of light of back light). The amorphous silicon film 3 of the thin film transistor 27 for display and the photoelectric converting layer 4 of the thin film transistor 28 for photodetection are formed in the same process.

Title: Image forming device
Inventor: SATO HIROSHI
IPC: G03G15/20
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of image quality caused by faulty fixation by temporarily fixing an unfixed image other than the final unfixed image at temporary fixing temperature lower than a fixing temperature, fixing the final unfixed image at the fixing temperature capable of fixation and further controlling the fixing temperature while considering the time lag of heat conduction in a fixing member in the case of switching temperature from the temporary fixing temperature to the normal fixing temperature. SOLUTION: In the case of fixing the unfixed image on a first side, the image is fixed on the first side under control in a state where the surface temperature of a fixing roller 7 is lower than the normal fixing temperature. When the image is transferred to the second side thereafter and recording paper is guided to a fixing device 6 again, the surface temperature of the roller 7 must be the normal fixing temperature necessarily in order to prevent the deterioration of the image quality. In the case of starting to fix the image on the second side, the setting of the fixing temperature is switched to be earlier by the time lag in the heat conduction so as to attain the normal fixing temperature, and then a heater 8 is started to be energized. At such a time, timing to switch the setting of the temperature is controlled by previously setting a different value according to the size of the recording paper and using the value.
