Title: Current collector for rolling stock
Inventor: SAITO HIDEFUMI
IPC: B60L5/20
Filed: 1991-10-31
Abstract: PURPOSE:To obtain a current collector for rolling stock in which a stringing can be protected against damage when a profile for reducing air resistance is employed in a current collecting member by detecting lift functioning onto the current collecting member and modifying the attack angle thereof. CONSTITUTION:Lift functioning onto a collector shoe 7 is detected by means of a diaphragm disposed in the collector shoe 7. A solenoid valve 31 for telescoping an air cylinder 9 is then operated such that a preset appropriate pushing force is applied onto a stringing 8 from the collector shoe 7 according to thus detected lift. Consequently, attack angle of the collector shoe 7 varies to control the pushing force. According to the constitution, the stringing 8 can be protected against damage by controlling the pushing force appropriately when disturbance of air flow is suppressed at the time of high speed traveling of vehicle in order to reduce noise by employing a stream line profile in the collector shoe 7.

IPC: B41J2/36
Filed: 1987-12-11
Abstract: PURPOSE:To control a thermal head substrate to have an optimum temperature even if the temperature of the thermal head substrate is increased or decreased, by controlling a conduction time according to tables provided separately for an addition processing time and a subtraction processing time. CONSTITUTION:According to an output signal from a counter 3, an arithmetic part 4 counts a value X of a subtraction counter as the total conduction dot number in the past in the same line and a value Y of an addition counter as the total non-conduction dot number in the past in the same line. On the other hand, in the arithmetic part 4, the numeric values of a subtraction table and an addition table are previously inputted for calculating a conduction time to a dot by the comparison between the aforesaid values X and Y. When a conduction time t(0)-t(n) is to be set short, the range of values B(0)-B(n) of the subtraction table is so set as to make a curve having a downward sharp grade in the initial period. If a conduction time is made longer, the range of values W(0)-W(n) of the addition table is so set as to make a curve having an upward sharp grade in the initial period.

Title: Picture reader
Inventor: UCHIYAMA MASAYUKI
IPC: H04N1/04
Filed: 1988-12-14
Abstract: PURPOSE:To attain the reduction of a picture without generating picture degradation by changing light receiving quantity added from an original to line sensor in correspondence to a picture reduction ratio and obtaining a mean value. CONSTITUTION:A line image sensor 13 is equipped with a CCD to transfer signals read from plural detecting elements in a linear direction. In a light quantity control means 24, the light receiving quantity to be added from an original 12 to the sensor 13 by one time scan is changed in correspondence to the reduction ratio. For example, when the reduction ratio in a main scanning direction is defined as (q) and the reduction ratio in a sub scanning direction is defined as (r), the light quantity to be added to one picture goes to 1/qXr. Every time the sensor 13 executes sub scanning for (r) line, a drive pulse generating means 25 gives a transfer command based on the command of a CPU 22 and the signals accumulated up to the moment are outputted. Thus, (q)X(r) picture element data are added by equal quantity and obtained as the mean value. Accordingly, the value of plural picture elements can be defined as the data of one picture element for the reduced picture and the satisfactory reduced picture can be obtained.
