Title: Pulse width measuring method
Inventor: ASADA YOSHIMI
IPC: G01R29/02
Filed: 1990-03-13
Abstract: PURPOSE:To hold performance nearly as high as E/O sampling as to frequencies which can be measured by observing an autocorrelation and a cross-correlation coefficient between signals after they pass through a 1st and a 2nd transmission line while giving a specific dielectric constant control input and varying the transmission speed of the 2nd signal transmission line. CONSTITUTION:A pulse signal 10 to be measured is inputted to the two signal transmission lines 8 and 9. The line 9 is covered with GaAs as a dielectric constant varying material 11, which is irradiated with laser light as the dielectric constant control input 13. Further, those lines 8 and 9 are terminated by resistances 14 and 15 for prevention against unnecessary reflection. An FET source follower circuit of two-gate constitution is employed as an autocorrelation coefficient calculating circuit 12 and a high voltage value is obtained on a voltmeter 16 provided on its output side when the autocorrelation coefficient is large. For this reason while the intensity of the laser light as the input 13 is varied, the voltage value on the voltmeter 16 is read to find the pulse width of the signal 10 reversely from their relation.

Title: Rotational resistance generating device
Inventor: ITO KENICHIRO
IPC: F16D41/07
Filed: 1994-03-31
Abstract: PURPOSE:To prevent interference of an elastic member with the other member by decreasing fluctuation of pressing load to be generated by dimensional tolerance of parts in a device for providing pressing load to a contact part of a resistance case with an input ring by the elastic member, and for generating rotational resistance by frictional force to be generated on the contact part. CONSTITUTION:A flange 20 of an input ring 18 and a flange of a resistance case 17 are pressure connected to each other by using a wave, spring 22 around which a wave-like spring plate is wound into a coil shape, so as to generate frictional force. Since the wave spring 22 can generate large pressing load by its small spring constant, fluctuation of pressing load can be decreased even if there is dimensional tolerance of parts. Moreover, the diameter of a spring 22 is extended during the rotation of the input ring 18 by reversing the winding direction of a coil of the wave spring 22 in relation to the rotational direction of the input ring 18, thereby interference with the part on the inside diameter side can be prevented.

Abstract: PURPOSE:To shorten the processing time of a bit operating instruction by using the corresponding instruction stored in a control memory and the mask value data to process the data on the bit operating instruction. CONSTITUTION:When a bit operating instruction is set to an instruction register 1, a selector 6 selects the output of an adder 5 by the signal of a signal line 6A of a decoder 4. While the addresses b0-bn corresponding to the operating bit position data on the bit operating instruction outputted from the adder 5 are set to an address register 8. The mask value data X0-Xn contained in the microinstruction read out of a control memory part 9 are used in response to those addresses b0-bn to read out immediately the data on the operating part (bit). In other words, it is not required for a microprogram to calculate the byte address of the operating part (bit). Thus the processing procedure is simplified and the processing time is shortened with the bit operating instruc tion.

Title: Liquid jet recording head and recorder using the same
Inventor: TAKENOUCHI MASANORI
IPC: B41J2/175
Filed: 1992-03-19
Abstract: PURPOSE:To shorten refilling time by controlling unnecessary forcing back of ink to an upstream side by a method wherein a liquid passage has a constriction part wherein a sectional area normal to the liquid passage is minimized at a position corresponding to a heat action part to control a size of a bubble to be generated. CONSTITUTION:By structuring a heat action part on a heating element part 1 so as to have a part wherein the sectional area of an ink passage is minimized on a discharge opening 12 side from a defoaming point 2 at a position corresponding to the heat action part, energy in foaming can be separated in a discharge direction and on an upstream side. Further, by concentrating even energy being transmitted upward in an ink passage in foaming by a structure slanting toward the discharge opening 12, discharge speed of the ink can be increased. On side angle (beta) forming a minimized part H is made less than an angle (alpha) in order to lighten propagation of energy to the upstream side. Further, a surface on the discharge opening 12 side generates flow resistance to an ink flow from the discharge opening 12 side to decrease a regression side of a meniscus during a shrinking process of a bubble, which further generates a turbulent flow on the upstream side of the minimized part H to restrain the ink from moving to the upstream side.
