Title: Mobile communication system
Inventor: OMOTO RYUTARO
IPC: H04B7/02
Filed: 1991-12-02
Abstract: PURPOSE:To miniaturize, simplify and economize a base station and a centralized base station by using an oscillator which is used at the time of frequency- multipllexing a diversity signal of up/down lines in the base station and the centralized base station in common. CONSTITUTION:The constitution of the system is that the centralized base station 1 and the base station 2 are connected by optical fibers 12 and 31 which are respectively the up/down lines. Then, in this case, the oscillator 17 outputting the signal for frequency conversion in the case station 2 and the oscillator 57 outputting the signal for frequency conversion in the centralized base station 1 are used for the up/down lines in common. Namely, in the base station 2, receiving signals from plural antennas 23 and 24 are transmitted to the centralized base station 1 by frequency-converting one of the receiving signals and frequency-multiplying the plural receiving signals base on the signal from the oscillator 17 shared for up/down. In the centralized base station 1, the signal is separated and demodulated by the signal from the oscillator 57 shared for up/down. The signal from the centralized base station 1 to the base station 2 is transmitted like this.

Abstract: PURPOSE: To increase the amount of oxygen supplied to a cathode surface so as to enhance oxygen pressure by providing a fuel gas channel and an oxidizing gas channel, and forming at least the oxidizing gas channel into a shape curved within a plane perpendicular to electrodes. CONSTITUTION: To allow the polyelectrolyte film 12 of a fuel cell 11 to contain water to a saturated state so as to function as a proton-conductive electrolyte having a specific resistance of 20Ω.cm or less at room temperature, steam is mixed in hydrogen gas supplied via a fuel gas channel 17 and in air supplied via an oxygen gas channel, so as to keep the film 12 wet. In an anode 14, H2 gas circulating through the channel 17 and protons together form electrons. In a cathode 13, oxygen in air flowing through the channel 16, protons migrating within the film 12 from the anode, and electrons migrating through an external circuit react with one another to produce water.  Since the channel 16 is formed into a circular shape, secondary flow is produced in stratified air flowing within the channel 16, and the amount of gas supplied to the surfaces of electrodes is increased by the stirring action of the secondary flow and by a rise in flow velocity, resulting in enhanced outputs.

Title: Method for determining dressing state
Inventor: TAKAHARA MOTOAKI
IPC: B24B53/00
Filed: 1991-11-06
Abstract: PURPOSE:To completely automate the dressing work by readily performing appropriate dressing at all times even by an unskilled worker. CONSTITUTION:An AE wave (ultrasonic vibration) generated from the contact part of a rotary dresser and a grinding wheel is detected with a vibration detecting means provided on the rotary dresser. The dressing state of the grinding wheel is determined from the generated frequency of the AE wave in its output signal SAE. Full-wave rectification is applied to the signal SAE. The roundness of tire grinding wheel is determined by deciding whether the waveform of a signal SAEL 1 passed through a low-pass filter corresponds to the rotating cycle of the rotary dresser or not. Axial flatness at the outer circumferential surface of the grinding wheel is determined by deciding whether the signal strength of a signal SAEL 2 for the duration of axially traversing the grinding wheel to the rotary dresser is nearly constant or not.
