Title: Pcm radio transmitter-receiver
Inventor: WATANABE SHOJI
IPC: H04B1/50
Filed: 1988-02-29
Abstract: PURPOSE:To operate an automatic cancel circuit normally by interposing a speed conversion circuit respectively to the sender side and a receiver side, setting the 1st and 2nd equipments applying full duplex communication at a different speed respectively so as to allow its own station to distinguish clearly the signal from an opposite station even at a loopback test. CONSTITUTION:The speed conversion circuits 11A, 11B are interposed to the input side of the automatic cancel circuit 12 at the sender side and the speed conversion circuits 19A, 19B are interposed to the output side of the automatic cancel circuit 12 at the receiver side. The speed conversion circuits 11A, 11B and one or several bits of signal to input data signal 1 to increase the transmission speed. Furthermore, the speed conversion circuits 19A, 19B separate the added one or several bits of signal and restore the speed to the original input data transmission speed. Thus, the transmission signal of its own station and the reception signal from an opposite station are distinguished clearly so as to operate the circuit automatically cancelling the residual component of transmission.

Title: Electrophotographic copying machine
Inventor: HASHIMOTO KAORU
IPC: G03G15/04
Filed: 1986-03-03
Abstract: PURPOSE:To prevent the temperature of original glass from rising more efficiently by measuring previously variation in the temperature of the original glass from the level of the quantity of exposure and an exposure time and estimating the temperature of the original glass. CONSTITUTION:The temperature T of the original glass is not detected by using a sensor and variation in the temperature T with time is estimated from the quantity of lamp light (exposure level) to control operation. When the copying operation is in process, the rising temperature is estimated and when not, cooling temperature is estimated; when a timer which indicates the time of temperature estimation counts up to a specific value, it is decided whether or not the original glass temperature T is lower than a temperature level T1. Then it is decided whether or not the original glass temperature T is lower than a temperature level T2 and the cooling temperature is estimated; and then it is decided whether or not T is lower than T0 and if so, a cooling fan is stopped, thereby making a return. The temperature rises during the copying operation owing to exposure, so a temperature increment corresponding to each mode and each exposure level is added to the timer at constant intervals of time, thus estimating the temperature rise.

Title: Fuel, compressive ignition engine, and burner
Inventor: KAJITANI SHUICHI
IPC: F02D19/08
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain a fuel causing no actuation failure of e.g. fuel injection valves due to abrasion and having considerable NOx-diminishing effect by mixing pressurized and liquefied dimethyl ether and a liquid hydrocarbon with each other in specified volume proportions. SOLUTION: This fuel is obtained by mixing (A) 30-60 vol.% of pressurized and liquefied dimethyl ether and (B) 70-40 vol.% of a liquid hydrocarbon with each other; wherein the component B may be a light oil or liquefied natural gas. Furthermore, when the dimethyl ether is incorporated with carbon dioxide previously, or CO2 -contg. crude dimethyl ether is used, the carbon dioxide is released when the dimethyl ether is depressurized and boils in air, thereby lowering the combustion temperature of this fuel, leading to suppressing NOx generation in its combustion, therefore being favorable. The 2nd objective compressive ignition engine is constructed in such a manner that this fuel is pressurized so as to liquefy the dimethyl ether and, in this state, is fed, from a fuel cylinder via a fuel feed pipe 14, to a fuel injection valve 16 and then injected into a fuel chamber.

Title: Optical equalizer
Inventor: SHIMIZU KATSUHIRO
IPC: H04B10/2525
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To generate dispersion by applying temperature gradient and to change variance into a desired value by providing a temperature gradient applying means which a applies a temperature gradient in the optical signal propagation direction of an optical waveguide having a diffraction grating. SOLUTION: Temperature applying means 5a and 5b apply heat to an optical waveguide 1. In such a case, thermal gradient is generated on the waveguide 1 and a diffraction grating 2 by making the heat value generated by the means 5a different from the heat value generated by the means 5b. Since the refraction factor of the waveguide 1 is a function of temperature, the equivalent refraction factor Neff of the grating 2 also becomes a function of temperature. Thermal gradient applied by the means 5a and 5b is led to a distribution of a waveguide longitudinal direction to the factor Neff, too. Then, an effect being the same as a chirped grating is generated by the thermal gradient, and when wavelength is different, a distance to a reflection point is different to generate dispersion.  Dispersion quantity to be generated is changed by changing thermal gradient applied to the grating 2 in this way.

Filed: 1987-03-04
Abstract: PURPOSE:To measure shading data including an image formation optical system and to perform accurate shading correction by arranging an optical path switching means between the image formation optical system and a recording medium and detecting various light states by a photodetecting means. CONSTITUTION:A mirror 20 as the optical path switching means is arranged between the image formation optical system 30 and photosensitive material 5 and reflected light from the mirror 20 is image-formed on an a-Si area sensor as the photodetecting element. The mirror 20 is arranged as shown by a full line at the time of calibration and the optical path of the light from the optical system 30 is reflected by 90 deg. and guided to the sensor 21. The mirror 20 moves to a position shown by a dotted line at the time of image recording and moves away from the optical path. This sensor 21 is a single sensor and when spot light strikes, its output does not depend upon the place of the sensor. Consequently, the shading data including the optical system 30 is measured and the shading correction is performed more accurately.

Abstract: PURPOSE: To minimize the capacity of a motor, extend the life of a contact part, and reduce a work such as wiring at assembling by cylindrically forming a circuit movable contact body to make the friction accompanying the move ment closer to the rolling friction. CONSTITUTION: In a circuit contact of a motor driving type switch A, fixed contact bodies 9a and 9b are connected to 9d and 9e through circuit movable contact bodies 3a and 3b, respectively. Other circuit contacts are also connected in the same manner. When a voltage is applied to fixed contact bodies 9s, 9t connected to a motor driving movable contact body 5a, a motor is rotated to rotate a movable contact body holder 2 clockwise. A built-in spring type stopper 7 is moved together with the holder 2 until it reaches the position of the stopper groove 8a of a fixed contact body holder 8, whereby the switch is changed over. In this case, the friction accompanying the movement of the body 3a bets close to the rolling friction to minimize the force necessary for switching of the contact, and the capacity of the motor can be minimized.
