Title: Dc electric railcar for different voltage sections
Inventor: WATANABE ASAKI
IPC: B60L15/20
Filed: 1994-07-29
Abstract: PURPOSE:To drive an existing DC electric railcar through a section in which a trolley wire voltage is raised and a conventional voltage section by providing a step-up/step-down circuit in the existing DC electric railcar. CONSTITUTION:The terminal of a step-down switching element 3 is connected to that of a reactor 5 and the terminal of a DC motor 2 is connected to that of the ground 9 via a step-down diode 7. A step-down switching element 4 is connected to the terminal of a reactor 6 and the motor 2 is connected to the terminal of the ground 9 via a step-up diode 8 in a step-down circuit 16. In a section in which a trolley wire voltage is double stepped down, the applied voltage of a pantograph 1 is doubled as compared with the voltage of the conventional voltage section, and hence the step-down switching elements 3, 4 of the circuit 16 are alternately turned ON, OFF in the conducting width of 180 deg., thereby stepping down the applied voltage of the motor 2 to 1/2, and setting it to the same voltage as that of the conventional voltage section. Thus, the existing DC electric railcar can be driven through the section in which the wire voltage is double stepped up and the conventional voltage section.

Title: Electrophotographic copying machine equipped with image density correction device
Inventor: KAZAKI YUUICHI
IPC: G03G15/16
Filed: 1991-08-07
Abstract: PURPOSE:To stabilize image density without reference to the fatigue of a photosensitive body. CONSTITUTION:When a copy start switch is turned ON in a step ST1, it is decided in a step ST2 whether or not fixation temperature T is below 100C. When T is below 100C, an advance to a step ST4 is made and when T is above 100C, an advance to a step ST3 is made. In the step ST3, it is decided whether the wait time of the copying machine is >=2 hours or not. When the wait time is <=2 hours, an advance to a step ST7 is made. In the step ST4, it is decided whether or not the surface temperature T0 of the photosensitive body at the time of image density correction before copying operation is <=30 deg.C and when To is >30C, an advance to a step ST6 is made to perform the image density correction. When T0 is <=30 deg.C, an advance to a step ST5 is made and the image density correction is performed. Then an advance to the step ST7 is made and a copy cycle is executed.

Title: Bag
Inventor: INABA SHINICHI
IPC: B65D33/00
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To enable an easy insert of a nozzle into an inlet of a receiving container for transferring liquid or powder and granular contents by making a tapered nozzle protrude from an end of an upper rim with a side face joined. SOLUTION: Since a nozzle 5 is formed in a tapered shape (20 to 70 deg.) protruding from an upper rim 4b, a tip 5a can be cut off by a single operation, thereby easily forming an outlet 6 for discharging contents. Even if a receiving container for transferring contents discharged from a pouch container l is bottle-like having a small inlet, the tapered nozzle 5 can be easily inserted into the inlet of the receiving container, thereby allowing quick refilling without spilling the contents. In addition, the pouch container l is folded or the like at the time of squeezing, wherein since the nozzle has been provided protruding, side faces 2a, 2b or the like may not interfere with the outlet 6 formed at a tip of the nozzle 5.

Title: Advance detection profile control device using photosensor
Inventor: YAMAZAKI ETSUO
IPC: B23Q35/128
Filed: 1983-10-25
Abstract: PURPOSE:To improve the copying precision by outputting a quick-change portion output signal from a comparing/judging section and decreasing the copying speed when the difference of the light receiving level between two light receiving elements receiving the light radiated from a light source and reflected by a model surface is a predetermined value or more. CONSTITUTION:In a profile control device, the reflected light from a model 10 is reflected by half mirrors 22, 23, and it is entered into a light receiving element 28 and is converted to an electric quantity. An output difference detecting section 32 determines the difference between signals generated by amplifying the outputs of light receiving elements 26, 27 with amplifiers 30, 31, a comparing/judging section 33 compares the output of the output difference detecting section 32 and a reference value, and it feeds the detection signal to a control section 34 when a quick-change portion exists on the model surface. When a probe 11 approaches the quick- change portion of the model 10, the center of the reflected light flux of a light source 20 is made off the center of the out-going light flux, the light receiving level of the light receiving element 28 is decreased, but the light receiving level of a light receiving element 29 is not changed, thus the output of the output difference detecting section 32 is increased, and the quick-change portion can be detected by the comparing/judging section 33.

Title: Infrared absorption analysis method
Inventor: OSAWA MICHIO
IPC: G01N21/3563
Filed: 1984-09-27
Abstract: PURPOSE:To measure an IR transmission spectrum and IR reflection spectrum with the same sample by forming a thin film or layer of a sample on a base plate such as crystal silicon plate which has a large refractive index and allows the transmission or IR rays. CONSTITUTION:The base plate 5 is constituted of the single crystal silicon plate which has the refractive index of a large value and is finished to a specular surface. The thin film 2 of the sample to be measured is stuck on the surface of the plate 5 and the refractive index of the film 2 is smaller than the refractive index of the silicon crystal. The single crystal silicon plate as the plate 5 allows about 50% transmission of IR light and therefore the measurement by a transmission method is made possible by irradiating the IR light thereto from above the film 2. Since the difference in the refractive index between the film 2 and the plate 5 is large, the reflectivity at the boundary face between the film 2 and the single crystal silicon plate is large and the measurement of the reflection with the same high sensitivity as with a metallic plate is made possible.
