Abstract: PURPOSE:To reduce the amount of data so as to shorten the communication time by automatically receiving an order sheet with black-and-white bar codes composed of thick bars having a short longitudinal size transmitted by facsimile and performing black-and-white recognition on bar codes, mark sheets, and numerals after detecting their positions and automatically segmenting them. CONSTITUTION:Compressed data sent to a network controlling section 16 through a telephone line are stored in a file management storage device 7 under the same compressed condition after the data are demodulated into digital signals by means of the MODEM of a demodulating section 17 and, at the same time, reproduced to image digital data at a decoding section 18. Then a order sheet bar code segmenting/recognizing section 19 recognizes a bar code 8 on an order sheet 100 and understands that the sheet 100 is the order sheet 100 for household delivery. Then the section 19 recognizes various kinds of bar codes, but the bar codes can be compressed efficiently by the MH or MR coding, namely, the G3 machine coding, since each bar code is formed of thick bars having a short longitudinal size. Therefore, the amount of data is reduced and the transmission time is shortened.

Title: Battery tool
Inventor: TAKAADA KENICHI
IPC: H01M50/247
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To prevent collection of the hydrogen gas in a battery chamber, so as to prevent an explosion, by communicating a motor chamber housing a motor, and the battery chamber housing a battery, and exhausting the hydrogen gas generated by an overdischarging to the outer side forcibly. SOLUTION: When the capacity of a battery 1 is reduced by continuing the operation, the hydrogen gas is generated in a battery chamber 7 by the pole reversing. However, since the pressure in a motor chamber 6 is reduced in the operating condition of a battery tool, by rotating a fan 10, and the motor chamber 6 and the battery chamber 7 are communicated through a ventilating hole 9, the hydrogen gas generated in the battery chamber 7 is discharged outside forcibly through the ventilating hole 9, the inside of the motor chamber 6, and air holes 13. Since the hydrogen gas is not stored by the pole reversing in such a way, an explosion is never generated even if a spark is generated at the contact part of a terminal 2.

Title: Control type liquid-filled engine mount
Inventor: DOI MITSUHIRO
IPC: F16F13/30
Filed: 1989-11-02
Abstract: PURPOSE:To prevent a violent shake of a power unit at an engine stop by applying voltage to an orifice for a required duration when the position of the engine stop is detected from a signal of a position of an ignition key. CONSTITUTION:When a position of an engine stop is detected from a signal of a position of an ignition key by means of an engine stop detecting means h, voltage is applied to an electrode orifice e by means of an voltage applying means i for a required duration. By this voltage application, viscosity of electroviscous fluid g in the electrode orifice e increases. So, flow resistance in the orifice e also increases, and a spring constant of the engine mount itself is set higher. Consequently, a roll characteristic value of the engine rises, and its vibration level is lowered. Thus, violent shake of the power unit, which is caused by an engine cracking occurring just after the engine stop, is prevented.
