Patent JP-H06180741-A (JP)
Title: Data format
Inventor: TATEYAMA SEIJI
IPC: G06T13/00
Filed: 1992-10-14
Abstract: PURPOSE:To simply prepare data to be sent to a decoder and to simply describe a program by setting up the size of compressed data equally to bus width or to its integer times. CONSTITUTION:Since run length is reduced against the increment of display colors, the preparation of compressed data is ruled as follows based upon this phenomenon. Nemely compressed data are defined as fixed length and the length is defined as data bus width or its integer times. When the palet code of a display color mode is extended, the run length is shortened in reverse proportional to the code length (1). When the value of the run legth is excessively increased and can not be included within the fixed lenth, the run length of the fixed length is defined as '0' and the run length is specified in the succeeding record (2), (3). Consequently data to be delivered to the decoder can simply be prepared and a program can simply be described (4).

Title: Distance measuring apparatus
Inventor: HOZUMI YUJI
IPC: G01S7/48
Filed: 1986-12-17
Abstract: PURPOSE:To make distance measuring capacity high and stable regardless of changes in environmental temperature, by setting a bias voltage of an avalanche photodiode (APD) as a photodetector according to an electric noise to be generated at a breakdown. CONSTITUTION:An APD capacitor 9 is charged from a constant current source 4 through a resistance 5. The constant current source 4 is started each time distance measuring operation is performed and a constant is so set that a terminal voltage of a capacitor 9 is sufficiently lower than a breakdown before the measurement of the distance. When a voltage applied to both ends of a capacitor 9 rises with time to reach a breakdown voltage at a certain temperature, an electric noise appears due to the breakdown at an output of an amplifier 7 which amplifies an output of the APD 1 to transmit the state of an FF 10. An output of the FF 10 is introduced to a switch driving circuit 11 to close a switch 8. The voltage of the capacitor 9 is kept at a constant level by closing the switch 8 as discharge is prevented with a diode 6 through the switch 8 along with no more rise in the voltage.

Title: Detecting circuit for output overcurrent
Inventor: ICHIKAWA HIROMITSU
IPC: G01R19/00
Filed: 1990-11-08
Abstract: PURPOSE:To prevent incorrect detection of output overcurrent by providing a quick discharge circuit in addition to a filter circuit, and quickly discharging the electric potential of a capacitor immediately after and each time the peak value of output current is completed, so as to allow the potential of the capacitor to revert to its state before its peak value is generated. CONSTITUTION:When the peak value of a voltage signal 1' from an output current sensor is eliminated by the action of a quick discharge circuit 3, the terminal voltage 2' of a capacitor C located in a filter circuit 1 is allowed to quickly revert to its state before its peak value is generated. Even if the voltage signal 1' from the output current sensor periodically generates peak values, the terminal voltage of the capacitor C would not therefore be raised in a cumulative way and so the conventional problem of detecting output overcurrent by mistake can be solved and stable operation of a source device is made possible.

Filed: 1987-12-01
Abstract: PURPOSE:To ensure cutting tows smoothly, by setting the blade spacing and thickness in a drum cutter-type fiber cutter fitted with a plural of rider rollers and the coefficient of friction of the cut short fibers within specified ranges, respectively. CONSTITUTION:Tows Y in which the coefficient of friction after cut has been set at <=60mm by affording a lubricant are introduced through the feed roller 15 and wound around a drum in which cutting blades 12 have been embedded radially. The increments of the wound tow thickness are partly cut by the first rider roller 20 starting from the inner layer of the wound tows being in contact with the cutting blades, resulting in discharge into the drum; which is succeeded by further cutting in a similar manner by the second rider roller 20'. Said cutting blades are set so that the spacings between blades l is <=6mm and the blade thickness t satisfies the relationship: t/l<=0.4, thus obtaining the objective staple fiber with a cut length of <=6mm. The lower the coefficient of friction is, the more liable to drop by slippage the cut fibers are.
