Filed: 1981-12-04
Abstract: PURPOSE:To avoid the useless shift of a head and to realize an effective use of a memory, by shifting the head only at the area where a picture exists. CONSTITUTION:A head calculates an algebraical sum of the luminance of three detecting elements which are included within a pattern formed by image sensors 1-3 and then shifts in the direction where the algebraical sum is small in the traveling direction of the head.

IPC: B41J2/175
Filed: 1988-08-05
Abstract: PURPOSE:To detect the abnormality of a head by generating bubbles by electrolysis in a liquid in a liquid chamber between a pair of electrodes installed into the liquid chamber, applying voltage so as to change the volume of bubbles by discharge and detecting the currents of the electrodes. CONSTITUTION:Voltage pulses are applied to one of at least a pair of electrodes 10, 11 of a recording head 1 from a driver 2 in response to a recording signal from a CPU 7, and currents flowing between the electrodes at that time are detected by a current detecting means 4, and transmitted to a voltage comparator 5 as a voltage signal. The voltage signal from the current detecting means 4 and predetermined comparison voltage (one or the plural) from a comparison voltage source 6 are compared by the voltage comparator 5, and the result is transmitted to the CPU 7 and a signal 8 is emitted in accordance with a comparison result with the voltage of the comparison voltage source 6. Accordingly, since the presence of a residual bubble 13 can be detected, the bubble may be discharged only when there is the bubble, thus eliminating the unnecessary stand-by time and also preventing the waste of ink.

Filed: 1984-09-21
Abstract: PURPOSE:To obtain the cell of one element/bit for the high integration of an EEPROM by changing the electric potential of a data line above an external electric power source or below 0V when reading the information of a memory cell. CONSTITUTION:A pulse generated by the change of the address of an address buffer 81 is outputted from a control circuit 82 to a signal line 83 for bootstrap and charges a data 86 selected by a Y decoder 84, a Y switch 85 above 5V, for example to 7V by the bootstrap. The charged data line is changed in electric potential by the condition of a memory cell selected by an X decoder 88 (memory array 89). This signal change is detected by a sense amplifier 90 and outputted through an output buffer 91 to the outside. Thereby, the memory cell can be constituted with one element of a memory transistor capable of taking threshold voltages of a positive and a negative, and even if the threshold voltage of the transistor of a non selecting memory cell belonging to the same data line is negative, the information of a selecting cell can be correctly read.

Title: Speed change control device for automatic transmission
Inventor: AOKI TAKASHI
IPC: F16H59/20
Filed: 1988-08-06
Abstract: PURPOSE:To perform a smooth speed change by setting the coupling force of a latter stage speed change means in response to the estimated torque for a fixed time until the synchronization of the input/output rotations is judged then increasing it to the preset coupling force at the time of power-on shift- down. CONSTITUTION:When power-on shift-down is detected by a kick-down detecting means (c), the preceding stage speed change means (e) of a transmission (f) is released, thus the engine rotation is quickly increased, input/output rotations of a latter stage speed change means (e) quickly approach to be synchronized. A speed change coupling force setting means (d) sets the coupling force in response to the torque from an engine which would be transmitted if the latter stage speed change means (e) has the complete coupling, estimated by a transmitted torque estimating means (b), for a fixed time until the synchronization of rotations judged by a synchronization judging means (a). Subsequently, when input/output rotating speeds are judged to be synchronized, the coupling force of the latter stage speed change means (e) is increased to the preset value. The occurrence of a speed change shock and the blow-up of the engine rotation can be suppressed.
