Title: Ink viscosity detector for ink jet recorder
Inventor: ISHIMA KAZUMI
IPC: G01N11/16
Filed: 1980-03-17
Abstract: PURPOSE:To detect the viscosity of an ink liquid with high accuracy by a method wherein parallel friction plates and a vibrating plate disposed therebetween are provided, and the ink liquid viscosity is detected from the time difference obtained when the vibrating plate is moved in the gap between the friction plates in an ink liquid. CONSTITUTION:The ink viscosity detector is provided with friction plates 10 having a parallel gap 11 and a vibrating plate 12 disposed in the parallel gap 11, the vibrating plate 12 being connected to a plate spring 14 through a connecting rod 13, and the friction plates 10 and the vibrating plate 12 being submerged in an ink to be measured. When an electromagnet 16 is excited, an attraction plate 15 moves downward being attracted by the electromagnet 16, causing shielding plates 21 and 22 to move, and said movement is detected by photosensors 19 and 20. Hereupon, the output signal of the photosensor 19 is delayed by time t1, and the output signal of the photosensor 20 is moreover delayed, by time t1+t2, owing to the viscous resistance of the ink. Accordingly, if the mechanical loads other than the viscous resistance of the ink are regarded as constant, the viscosity of the ink can be highly accurately measured from the time difference between the output signals of the photosensors 19 and 20.

Title: Synchronous semiconductor storage device
Inventor: FURUYA KIYOHIRO
IPC: G11C11/407
Filed: 1995-02-22
Abstract: PURPOSE: To highly speed up the access time in a synchronous DRAM. CONSTITUTION: An internal clock signal int.CLK having a proper phase shift from an inputted external clock CLK is generated by delaying the external clock CLK by a delay time settled by an address signal by an internal clock signal generating circuit 9A. For example, when only an output TS0 out of outputs TS0-TS3 of a latch circuit becomes an H level as specified by the address signal, the external clock CLK is outputted via inverters 1-8, and hence a delay time of the internal clock signal int.CLK behind the external clock CLK is 2nsec. Then, when only the outputs TS1, TS2 and TS3 become the H level respectively as specified by the address signal, their respective delay times are 6nsec, 8nsec and 10nsec.

Filed: 1988-02-17
Abstract: PURPOSE:To perform a safe cutting work, by a method wherein a state in which drive torque is decreased during transfer of drive torque from an unstable region to a stable region can be displayed. CONSTITUTION:When it is decided that drive torque exerted on a transmission spring serving as a rotation transmission member does not enter a stable region, a CPU 3 executes computation to determine the decrease factor of drive torque. Based on a calculated decrease factor, a display control signal is outputted to a display drive circuit 43 to light, in order from the display unit 42a side, only by the number of display units, equivalent to a decrease factor, of ten display units 42a-42j. Thus, only by observing the number of the lighted display units, a worker detects that present drive torque is decreased to what degree. When the decrease value of drive torque is decreased to a value lower than a torque reference value, the CPU 31 outputs a movement control signal to a valve drive circuit 41 to switch a solenoid valve 13 for control, and a drill is moved to a machining position. This constitution enables safe starting of a cutting work.
