Title: Device for eliminating difference between inner and outer pressures in cabin for underground
Inventor: KANEKO TSUTOMU
IPC: E21F17/00
Filed: 1995-05-30
Abstract: PURPOSE: To relieve the pressure difference between the inner and outer parts caused by a variation of air pressure by interrupting the outer and inner parts of an operator cabin covering the open penetration hole, and laying a rubber sheet shiftable to the inner and outer parts depending on the pressure difference of the inner air and outer air. CONSTITUTION: An inner and outer pressure difference eliminating device is disposed on the side surface of an operation cabin 2, and as the air pressure outside of the cabin 2 rises, the rubber sheet 31 of the device comes inside from the side surface of the cabin through pressure difference. Next, as the volume within the cabin 2 decreases, the pressure of air within the cabin 2 becomes high and the pressure difference between the inner and outer parts is solved. In the case when the pressure outside of the cabin 2 has decreased, the rubber sheet 31 expands outside from the side surface of the cabin 2 through pressure difference with resultant increased volume within the cabin 2, and simultaneously, the air pressure within the cabin lowers, the pressure difference of the inner and outer pressures is solved.  In this way, even in the case where the air pressure within the underground varies, air pressure difference between the inner and outer parts of the cabin 2 is relieved and airtightness thereof is kept to inhibit dust and noise from invading inside and prevent window glass from being broken.

Title: Radio communication equipment
Inventor: KIKUCHI YASUYUKI
IPC: H04B1/40
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To prevent modulation sensitivity from being decided by a switch on/off changeover separation characteristic and to avoid the operation from being unstable when the switch is turned off with respect to the radio communication equipment adopting a half duplex communication system where the switch is used to turn on/off an oscillation signal from a local oscillator by means of an ASK modulation signal so as to conduct ASK modulation. SOLUTION: A switch 12 switches a signal from a local oscillator 11 by means of an ASK modulation signal, a multiplier 18 is controlled by on/off signals to obtain a multiplied transmission signal. Since the operation of the multiplier 18 is controlled by on/off of the switch 12, ASK modulation is attained without giving any direct effect of the separation characteristic of the switch 12 onto the modulation sensitivity. When the switch 12 is open, the ASK modulation is conducted stably at all times by terminating an input terminal of the multiplier 18 with a load resistor 17 whose resistance is low.

Filed: 1989-05-26
Abstract: PURPOSE:To generate a vector with a high data compression rate and high quality by performing one time of scan by calculating the degree of curvature of a curve, and employing a system to select a point having high degree of curvature. CONSTITUTION:A curvature degree calculation means 102 calculates the degree of curvature of a remarked point based on the coordinate data of a coordinate data storage means 101. A point interval threshold value selection means 104 selects a point interval threshold value corresponding to the degree of curvature calculated at the curvature degree calculation means 102 from a point interval threshold value storage means 103, and a counter 105 indicates the number of points from a selection point just before to a point being remarked at present. A selection judging means 106 stores the coordinate of the remarked point in a selection point coordinate data storing means 107 when the number of counts exceeds the point interval threshold value, and increases the number of counts of the counter 105 by one when the former is less than the latter.
