Patent JP-S6420535-A (JP)
Title: Image reader
Inventor: IWATA MASAKATSU
IPC: H04N1/00
Filed: 1987-07-15
Abstract: PURPOSE:To normally plate read-out stereoscopic originals and plural sheet originals on a paper discharge tray by setting said tray so as to be almost horizontal and to tilt at 10 deg. or above. CONSTITUTION:When the stereoscopic originals are read out, a microswitch 22 is turned on because a guide unit 19 is opened. When a microswitch 53 is turned on, the tray 9 is tilted by the microswitch 53, which may cause the following fault: when a hard, stereoscopic original is sent, its top edge is lifted by the tray 9, and said original 26 is beyond the focus depth range of a lens 17, and may not be read out properly. In such a case, a display displays 'tray checking' to draw an operator's attention. When the microswitch 53 is turned off, the tray 9 is horizontal, and operation enters a cubic mode.

Title: Socket for baseless electric lamp
Inventor: BABA MASAHARU
IPC: H01R33/18
Filed: 1991-07-17
Abstract: PURPOSE:To simplify the connecting structure by bonding a lead wire to a contactor while opposing a lead of a baseless electric lamp, through an opening part at the rear surface side of a flange, to an approximately U-shaped contactor forced in between the flange and a locking protrusion. CONSTITUTION:A U-shaped contactor 15, the lower side piece 15b of which is embeded in a fitting groove 17, is slid toward a center side from a circumferential direction of a flange 3. Hence, the contactor 15, the upper side piece 15a of which is elastically fitted to the lower side of the locking protrusion 4, is fitted in the space enclosed in a U-shape by the protrusion 4 and a rising wall 5 together with the flange 3. Namely, the lower side piece 15b of the contactor 15 is exposed to an opening groove 13, so that a tip of a lead wire 9 is directly bonded to the lower side piece 15b of the contactor 15 by brazing, soldering, welding, etc. In this manner, since all required is that the contactor 15 is embedded in the U-shaped space and the lead wire 9 is bonded to the lower side piece 15b of the contactor 15, mounting work is easy so as to enhance workability.

Inventor: KODAMA KUNIHIKO
IPC: H01L21/338
Filed: 1983-09-26
Abstract: PURPOSE:To prevent the adverse influence of a surface level, a surface depletion layer by forming source and drain electrodes on the surface of a semiconductor substrate, burying a single crystal metal gate electrode in the substrate, and forming a Schottky junction of the gate electrode for a semiconductor layer between the gate electrode and the surface of the substrate. CONSTITUTION:After an aluminum single crystal layer 12 is formed on a semi- insulating GaAs substrate 11, it is patterned to form a gate electrode 13. Then, an N type GaAs layer 14 is grown on the electrode 13, and a source electrode 15 and a drain electrode 16 are arranged on the layer 14. After these steps are finished, a surface protective film 19 is formed of SiO2 or Si3N4. Accordingly, since no gate electrode is disposed on the surface of the substrate, no leakage current occurs between the gate electrode and the source electrode, no adverse influence caused by the variation in the charge state of the surface level can be eliminated, and excellent characteristics such as low frequency noise and reduction in the transconductance are obtained.

Title: Signal processing unit
Inventor: SUZUKI SHIGEAKI
IPC: H04B3/23
Filed: 1994-07-28
Abstract: PURPOSE:To reduce the arithmetic operation quantity required for the signal processing unit. CONSTITUTION:A reception signal coded and multiplexed and received from a remote end channel is demultiplexed into a reception signal of each band by a demultiplexer section 12 and the result is outputted to a band split decoder 13. The band split decoder 13 decodes a reception signal of each band and outputs the result to a band split echo cancellation section 3 and a band synthesis processing 14. The band synthesis processing section 14 synthesizes reception signals of each band and outputs the result to a near end channel. A band split processing section 9 divides the transmission signal including an echo of the reception signal into plural bands and outputs it to a band split echo cancellation section 3. The band split echo cancellation section 3 cancels echo for each band and applies band division to the signal after echo cancellation and provides an output to a multiplexer section 11.

Title: Stopping device for unmanned carrier
Inventor: NOZAKI KOHEI
IPC: G05D1/02
Filed: 1986-07-28
Abstract: PURPOSE:To stop an unmanned carrier without using a stopping device nor a drive stop control mechanism by securing such a constitution where the carrier has the relative movement with revolutions of the carrier drive wheels when these wheels ride on a movable means set on the running course of the wheels. CONSTITUTION:An unmanned carrier 1 reaches a cargo station 5 and a rear wheel 3a rides on a belt device 7. Under such conditions, an optical sensor detects the pass of the carrier tip from a fact that the light sent from a light emitting part 12a is cut. Here an electromagnetic solenoid is energized to release the active mode of an electromagnetic brake 10. Thus a belt roller 8b can revolve freely. Therefore the wheel 3a skids on a belt 9 and the carrier stops there. When a prescribed time passed for loading and unloading cargoes, a controller sets the solenoid under a non-energized state and applies the brakes to inhibit the revolution of the roller 8b. As a result, the belt 9 is unable to move and the stop mode of the carrier is released. Then the carrier passes through the station 5 in a normal drive mode.

CONSTITUTION:A transfer sheet size detecting means 74 detects the size of the recording medium P housed in a housing means 56. The recording medium P is fed by the paper feeding means 57 and 58. On the other hand, an original set to an original platen 41 by a scanning means 46 driven by the scanning and driving means 100 is scanned, and an image is formed on the fed recording medium P with the aid of an obtained picture signal. At this time, a control part 76 controls the scanning and driving means 100 for each size of the recording medium P so that the feeding speed of the feeding means 57 and 58 coincides with the driving speed of the scanning and driving means 100. Consequently, the occurrence of the difference in the driving speed between the feeding systems and the scanning system can be prevented, regardless of the size of the recording medium.

The condensed water in the deaerator 45 is extracted by a bolder feed water pump 46 to heat the same in a feed water heater 47 and, thereafter, is supplied into a boiler 49. In this case, when one of two sets of the condensed water pumps 41, 42 under operation is tripped, the amount of water to be pumped by two sets of the pumps 41, 42 is digested by one set of the condensed water pump. However, a condenser spillover valve 51 is opened to discharge condensed water to the outside of a system when the water level of the condenser 40 is raised and has arrived at a set level.  On the contrary, when the load is to be lowered, the valve 51 is forcibly closed totally even when the level of the condensed water has arrived at the set level.
