IPC: G06F1/26
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To improve the battery utilizing efficiency of a portable terminal in the radio LAN system employing time division duplex(TDD) operations. SOLUTION: When a terminal station 8 does not conduct data transmission reception for a prescribed time, the terminal station 8 makes a battery save mode transfer request to a control station 1, and the station 8 transits the battery save mode after receiving permission by the control station 1. The control station 1 stores a state of the terminal station 8 to a terminal station state management table 6, and in the case that the control station 1 sends data to the terminal station 8 in the battery save mode, the station 1 sends a 'Wake-Up' instruction signal to the terminal station 8 and sends data after receiving a reception preparation end signal from the terminal station 8.

Title: Water depth/flow velocity sensor
Inventor: SAKAIMOTO MINORU
IPC: G08C17/00
Filed: 1994-11-25
Abstract: PURPOSE: To achieve continuous measurement in real time by sinking a case box in a stable state even when the rivers rise and the flow velocity varies every moment and eliminating damage by driftwood and running stones. CONSTITUTION: A holding tool 3 connected with a traction wire 2 in the vicinity of the center of gravity is set at a case box 1. A vane means is attached to the case box 1 to apply a force in the direction of gravitation. The case box 1 is let to sink to a designated position in a stable state by taking out the traction wire 2 with a partial force in the direction of the gravitation impressed from the running water when the vane means sinks in the water. In the running water, each water pressure generated at a dynamic water pressure hole 1a opened in parallel to the flow of water and a static water pressure hole 1b opened perpendicularly to the flow of water is detected by two pressure sensors and transduced into an electric signal. The electric signal is output via a communication line attached to the traction wire 2.  In this manner, measurements can be effectively continued even under such unfavorable circumstances that foreign articles are contained in the water flow or the sensor is exposed to strong wind.

Title: Crushing roller for coarse matrial crushing machine
Inventor: KOMODA MOTOAKI
IPC: B02C4/30
Filed: 1992-10-06
Abstract: PURPOSE:To improve crushing efficiency by scooping up the primarily crushed materials remaining between upper and lower crushing rollers and recrushing these materials. CONSTITUTION:The upper crushing rollers 2, 3 making an approximately parallel pair have screw-shaped crushing blades 5, 6, 10, 11. Partition plates 20 for partitioning the grooves between these screw-shaped crushing blades are mounted to at least one of the crushing rollers. These partition plates 20 are so inclined as to be disposed in the transfer direction opposite from the transfer direction of the coarse materials by the screws. As a result, the coarse materials are turned over and dispersed without being concentrated to the central part. Since the materials are recrushed by the entire part of the screw blades, the crushing efficiency is improved without lengthening the crushing rollers 2, 3.

Title: Process for roughening surface of organic electrophotographic sensitive body
Inventor: SAKO SHUNKAI
IPC: G03G5/00
Filed: 1988-11-21
Abstract: PURPOSE:To roughen a surface of a photosensitive body uniformly in a short time by regulating a relative grinding velocity of an abrasive to a specified value. CONSTITUTION:A photosensitive body 1 provided with an org. photosensitive layer constituted of layers of a charge generating layer and a charge transfer layer, etc., is revolved and ground while moving the photosensitive body 1 in a manner that a relative grinding velocity of a film abrasive to a contact surface of the photosensitive body 1 attains 1.0-5,000mm/sec. In this stage, the roughening result may be insufficient and ground parts leaving a minimum surface roughness below a desired value may be present if the relative grinding velocity is <1.0mm/sec. In this case, inversion of a cleaning blade, etc., may be caused. If the velocity exceeds 5,000mm/sec., the maximum surface roughness may increase, causing fear for generating image defect due to flaws.
