Patent JP-S60205251-A (JP)
Title: Ultrasonic microscope
Inventor: TAKAI MASAO
IPC: G01N29/06
Filed: 1984-03-30
Abstract: PURPOSE:To enable a highly accurate observation of a specimen with a simple operation by increasing or decreasing variations in a video signal obtained from a sound wave spherical lens with a specimen tilting base. CONSTITUTION:A specimen 7 is set on a specimen tilting base 14a and then, a video signal from a receiver 10 and a scan position data from a specimen base driving section 13 are inputted into a specimen tilt controller 16 tilting the base 14a to determine the sum X of absolute values of variations in the video signal at points. Then, the base is tilted in a certain direction to minimize the sum X varying the amount of tilting. Subsequently, this operation is performed in another direction perpendicular to the preceding direction within the 2-D plane. In this manner, the sum X in each scanning direction as obtained from the specimen 7 is minimized separately. In other words, the sum X increases when there are many interference fringes with scan lines over the specimen 7 not parallel relative to the sound wave spherical lens 1 while it decreases when they are parallel. Thus, the specimen 7 can be positioned parallel to the relative scan lines with the lens 1 by minimizing the sum X thereby enabling a highly accurate observation.

Title: Recorder
Inventor: NAKAZAWA AKIRA
IPC: G03G15/05
Filed: 1989-03-15
Abstract: PURPOSE:To obtain a small-sized high speed recorder having a simple structure and easiness for lining by using conductive wax ink and incorporating a heat source for melting ink in an ink supply roller. CONSTITUTION:An electrode 1 is buried linearly with metal at a pitch of 140mum on the surface of a platen 6. When an electric field of a power source 5 is not operated between conductive wax ink 8 and the electrode 1, the surface tension of the ink 8 is regulated. Thus, ink supplied to a retainer 2 cannot advance into a hole 3, and the ink does not arrive at a recording sheet 7. A voltage is applied between the ink 8 and the electrode 1 with the electrodes 5 at the time of recording to generate an electric field. Thus, the ink 8 is passed through the hole 3 by electrostatic force operating thereby to be adhered to the sheet 7. Thus, since a recording can be conducted merely by operating the electric field at the ink 8 and passing through the hole, its structure is simple, and can be lined to realize a small-sized high speed printer.

Title: Image forming device
Inventor: SHIMADA KAZUTOSHI
IPC: G03G15/20
Filed: 1987-03-18
Abstract: PURPOSE:To shorten a wait time and to reduce electric power consumption by providing a varying means for varying the conditions of an image forming process and providing a means for selecting the image forming mode different in the process conditions. CONSTITUTION:The means for selecting a copying mode (image forming mode) is constituted of a microcomputer 21 which controls the sequence of the entire part and the process conditions. The respective process conditions 1-3 are so selected that the copying is permitted even if the temp. of a fixing device is lower than the specified value in order to shorten the wait time. More specifically, the temp. of the fixing device is low in the process conditions 1, 2 and, therefore, the process speed is lowered by decreasing the driving quantity of a DC motor in such a manner that heat energy is applied at a higher rate to transfer paper and toner. An electrostatic charge quantity and exposure are accordingly set small as well. These process conditions 1-3 are determined by the temp. of the fixing device at the time of a copying start. The wait time is thereby shortened and the electric power consumption is reduced.

Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent the variation in the diameter of crystal particles by allowing halogen to be absorbed by the surface of an insulating film using halogen gas. SOLUTION: Fluorine radicals 103b are generated using, for example, fluorine gas 103a. Then, the fluorine radicals are supplied to a silicon substrate in a vacuum equipment to allow fluorine atoms to be absorbed by the surface of a gate oxide film. Nextly, amorphous silicon 106a is deposited using, for example, disilane gas. Then, a heat treatment is conducted to crystallize the amorphous silicon. After that, amorphous silicon 107 is deposited again. This time, most of the fluorine atoms absorbed by the surface of the oxide film are desorbed through crystallization and heat treatment of the first amorphous silicon and therefore the second amorphous silicon deposited this time is evenly deposited on the entire surface of the semiconductor substrate. Then, the second amorphous silicon is heat-treated and then is crystallized with the first silicon particles as growth nuclei.  Therefore, the silicon can be grown into polycrystalline silicon 108 of well-controlled grain diameter.

Abstract: PURPOSE:To mitigate the specification of an actuator without affecting the action position of a switch and improve the yield of products by using an oil spring wound with a coil member at a nonuniform pitch. CONSTITUTION:When the push button 13 of a push button switch 10 is pushed, a slider 14 is lowered along a housing 18, and a coil spring 1 and a rubber actuator 17 are elastically deformed.

Title: Sample holding circuit
Inventor: SONEDA MITSUO
IPC: G11C27/02
Filed: 1986-03-19
Abstract: PURPOSE:To perform excellent sample holding operation by correcting the offset between the input and output of a circuit. CONSTITUTION:When a switch 4 is turned on in a hold period phiH, the offset voltage held by a capacitor 6 is added to the signal potential held by a capacitor 3 and the sum voltage is applied to the gates of transistors (TR) 7N and 7P, so that the potential after the offset voltage is canceled appears at an output terminal 9. Namely, the offset voltage is added once to the signal potential and further subtracted, and a potential as high as the signal potential held in the capacitor 3 is outputted to the output terminal 9. Thus, the component of the component of the circuit is removed, so even if the offset voltage varies owing to the drift and variance of Vth and Io, temperature characteristics, etc., there is no DC potential variation between the input and output and the offset voltage is detected and removed at every sample period phiS, so there is not any probability of the generation of an l/f noise.
