Title: Radio communication equipment
Inventor: FUJII KATSUNORI
IPC: H04B1/40
Filed: 1995-03-06
Abstract: PURPOSE: To prevent the generation of an interference signal to a cable in a radio communication equipment having an indoor device and an outdoor device and capable of executing signal transmission between both the devices and power supply to the outdoor device by connecting the indoor device to the outdoor device through the cable. CONSTITUTION: An input signal inputted to a cable connection side input part in the outdoor device is passed through an intermediate frequency band pass filter (IF BPF) 1 for passing a prescribed band signal and inputted to a voltage control type band blocking filter (VCF) 2 to be controlled by a center frequency control circuit 8 and the signal with a fixed output level is outputted to an IF output through an automatic gain controlling amplifier(AGC AMP) 3. The output from the AGC AMP 3 is detected by an output level detector 4 and inputted to a comparator 7. On the other hand, an output from a cable length detecting circuit 5 for detecting cable length from a signal inputted from an IF input part is inputted to a table circuit 6 and a voltage value obtained by the calculation of the cable length is inputted to the comparator 7.  The comparator 7 compares both the voltage values with each other and controls the center frequency of the VCF 2 so that error voltage is minimized.

IPC: G02B6/38
Filed: 1981-03-30
Abstract: PURPOSE:To perform the connection of the optical fibers readily and accurately, by passing two divided parallel luminous fluxes, combining them, and connecting the fibers by observing the interference fringes. CONSTITUTION:The parallel monochromatic light emitted from a light source 221 is split into two parallel luminous fluxes through a half mirror 231 and a mirror 241. The fluxes pass the optical fibers 211 and 212. They are combined through a mirror 242 and a half mirror 232 and inputted to a microscope 222. By observing the interference fringes, the axes of the optical fibers 211 and 212 are aligned, and the connection is performed. Since the alignment of the optical fibers 211 and 212 can be performed at the connecting position, the connecting work can be performed readily and accurately.

Title: Dust protective device for front axle of agricultural tractor
Inventor: ASANO TSUTOMU
IPC: B60G9/02
Filed: 1978-04-18
Abstract: PURPOSE:To prevent the displacement of an oil seal and to enlarge the contact surface area by fitting the oil seal in such a manner as to stride the joint surface between a front axle and hollow short cylinders. CONSTITUTION:A front axle 7 is placed so as to extend over full length between hollow short cylinders 5 and 6, with collars 10 therebetween. An annular groove 8 is formed in the peripheral surface of each of the cylinders 5 and 6, and each collar 10 is covered by an oil seal 9 of which one end is embedded in the groove 8. Of the oil seal 9, the portion embedded in the groove 8 is of fixed structure, while the portion around the axle 7 is of slidable structure. Sewage and sand cannot penetrate in because the oil seals 9 are fitted around the joint surfaces between the axle 7 and the cylinders 5 and 6. The fitting of the axle 7 through collars 10 causes an 0-ring to be needless and enables the joint surfaces to be of thick and large-area structure.

Title: Dynamic brake for inverter electric car
Inventor: MIZOBUCHI TETSUYA
IPC: B60L7/06
Filed: 1986-03-05
Abstract: PURPOSE:To eliminate the need for a spare charger for charging a filter capacitor by mounting a device for blocking discharge to a discharge circuit for the filter capacitor. CONSTITUTION:When service is interrupted in a stringing when a regenerative brake is worked, a switch 8 is closed, and a brake resistor 4 is connected to an inverter. When service is interrupted during the coasting of an electric rolling stock, the charges of a filter capacitor 5 being charged under the state of power running before the service interruption are discharged. When charges being charged to the filter capacitor 5 are all discharged at that time, a rheostatic brake is not operated because the exciting voltage of a main motor is removed. consequently, discharge blocking devices 91 and 92 are fitted to all filter capacitor voltage discharge circuits, thus preventing the discharge of filter capacitor voltage. Accordingly, the rheostatic brake can be operated smoothly.

Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To automatically remove a DC offset which is mixed with a spectrum in an apparatus such as an electron spin resonance(ESR) apparatus or a nuclear magnetic resonance(NMR) apparatus. SOLUTION: A zero-correction circuit is composed of an amplifier circuit which uses two operational amplifiers 12, 13. A charging circuit which is composed of a capacitor C and of a resistance R1 is installed at the later-stage operational amplifier 13. A spectrum which is input is amplified by the amplifier circuit which is composed of the operational amplifier 12, it is output, and it is input to the later-stage amplifier circuit 13 so as to be amplified. At this time, the DC level of the spectrum appears at the capacitor C at the time constant of the charging circuit, and the level is negatively fed back to the front- stage operational amplifier 12 by 3 resistance R2 . As a result, when the DC level of the spectrum is deviated from a zero level, the DC level of the spectrum is canceled. Consequently, the spectrum in which the DC level is corrected to the zero level is obtained at the output of the zero-correction circuit.
