Title: Liquid jetting head
Inventor: YOSHIHIRA FUMI
IPC: B41J2/05
Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To jet liquid stably and efficiently. SOLUTION: A second liquid channel 4 for introducing bubbling liquid to the vicinity of a heater 2 is formed on an element substrate 21 and a first liquid channel 3 for introducing ejection liquid to an jetting opening 1 is formed on the lower surface of a grooved member 22. The first liquid channel 3 is located above the second liquid channel 4 while being separated by a deformable and movable separation film 5 provided with an undeformable block at a position substantially facing the heater 2. The part of a movable member 5 provided with a block 10 is displaced toward the first liquid channel without being deformed by a pressure generated as a bubble 6 is generated and grown by means of the heater 2 and transmits the pressure to the ejection liquid thus jetting the ejection liquid. Since the shape of the bubble 6 has no effect on the displacement of the movable separation film 5, the ejection liquid can be jetted stably. Furthermore, the ejection liquid can be jetted efficiently because the lower end of the block 10 is close to the heater 2.

Title: Electronic wave correction watch
Inventor: MAKUTA SHUNICHI
IPC: G04G5/00
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To facilitate the step advance of electronic clock hands by applying the minimum required drive pulse to a motor for driving the electronic clock hands when no standard electronic wave is analyzed, eliminating the need for high speed and improved functions by an interruption processing on analysis, and accurately reading the standard time. SOLUTION: A step advance interruption signal with a frequency of approximately 1 Hz is formed by a divider 43 for step advance timing by a step advance signal formation means 41 of a microcomputer 11, and a pulse width determination interruption signal with a frequency of approximately 32 Hz is formed by a divider 45 for pulse signals. When a motor drive pulse is outputted without analyzing a standard electronic wave, the output time of the motor drive pulse is measured based on a reference signal, and power consumption is reduced by the minimum required specific time width for the step advance of the motor.  When the standard electronic wave is to be analyzed, the output of a motor drive pulse is prepared by performing a step advance interruption, and an interruption processing is made at each time that is slightly longer than the pulse width time being required for the step advance of the motor, thus starting and stopping the output of the motor drive pulse.

IPC: A61B3/10
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To follow and trap a eyeground blood vessel with a module outputting the position and width of an object for accurate eyeground blood flow measurement. SOLUTION: An eyeground image with the movement of an eyeball is projected on a linear image sensor 70 via a rotation prism 52 and its image signal is sent to a differentiation circuit 83 and a comparison circuit 84 via an image clamper 80, an image filter 81 and an AGC circuit 82, where it is formed into a digital waveform containing blood vessel focused information. From such a signal and a signal passing through a delay circuit 85, a relative blood vessel position most near a scanning reference position on the eyeground is found by the blood vessel position calculation part of an arithmetic circuit 75.  Similarly, a digital signal containing blood vessel diameter edge information is obtained through the differentiation circuit 87, the filer 88 and the comparison circuit 89, which is used with a signal passing through the delay circuit 90 to resist a blood vessel diameter for every scanning in the blood vessel diameter calculation part of the arithmetic circuit 75 and send it to a control circuit 76. The signal is D/A converted and the rotating prism 52 is rotationally moved to rest a retinal blood vessel at a reference position on the linear image sensor 70 for following and trapping the eyeground blood vessel.

An image processor 14 further performs a processing to intensify the contrast of the interference fringe by binary coding.  The resulting binary coding data undergoes a statistical processing to be conducive to the standardization of the convex working evaluation and a GO/NO GO inspection.
