Title: Endoscope
Inventor: AONO SUSUMU
IPC: A61B1/04
Filed: 1999-07-13
Abstract: PROBLEM TO BE SOLVED: To provide an endoscope wherein the diameter of the insertion section is made smaller while improving the resistance to an autoclave sterilization, and the cost can be reduced. SOLUTION: The periphery of a circuit substrate 36 of a photographing device 24 which is provided at the tip end section 13 of an endoscope insertion section, is sealed with a sealing agent 42 made of a fluorine rubber.

Title: Solid-state image pickup device
Inventor: NISHIZAWA SHIGEKI
IPC: H04N5/374
Filed: 1988-08-10
Abstract: PURPOSE:To prevent adverse effect due to the dispersion in the element characteristic of a selected path by giving a voltage corresponding to a photoelectric conversion signal from a selection picture element cell to one electrode of a capacitor and bringing the other electrode into the floating state to obtain an output signal. CONSTITUTION:A photoelectric conversion voltage fetched in a capacitor CV1 brings a timing signal fed to a terminal CRP to an L level, thereby turning off a switch MOSFETQ20. Thus, the output side of the capacitor CV1 is brought into the floating state. Then a timing signal of an H level is fed to a terminal PDR and then a MOSFETQ1 is turned on because the vertical selection signal VS1 is at an H level and a precharge voltage is fed to the photodiode D1. Thus, the signal V1 of the capacitor CV1 is a voltage according to the precharge voltage and the output side is level-shifted. That is, only the photoelectric conversion voltage formed by the diode D1 appears at the output side electrode of the capacitor CV1.

IPC: G01F17/00
Filed: 1992-07-27
Abstract: PURPOSE:To obtain a volume meter for measuring volume always exactly without the effect of equivalent capacity of a sound source and the lowering of S/N ratio even with a large volume. CONSTITUTION:In an acoustic system constituted of a Helmholz resonator connecting an acoustic pipe 3 to a vessel 1, a volume meter measures each of the resonance frequency of a Helmholz resonator and resonance frequency of the auxilially acoustic resonator by driving the acoustic system with a sound source 10 provided independently outside the acoustic system. And based on the ratio between two resonance frequencies, vessel volume or the volume of a body contained in the vessel is obtained. As the sound source 10 is provided independently outside of the acoustic system of the Helmholz resonator, the acoustic system of the Helmholz resonator remains as a rigid body without causing reduction of resonance effect and thus, it is not affected by the equivalent capacity of the sound source at all.

Abstract: PURPOSE:To obtain a dielectric characteristic measuring method by which the dielectric characteristic of the material of a film, such as a plastic film, etc., especially, the dielectric characteristic (tandelta, etc.) in a high electric field can be measured with high accuracy. CONSTITUTION:When the title method by which the dielectric characteristic of a film is measured by putting electrodes of a dielectric characteristic measuring instrument on both sides of the film and making an electric current to flow from one electrode to the other electrode is used, metallic electrodes 12 and 13 are buried in both surfaces of a film 11 and the dielectric characteristic of the film 11 is measured by making an electric current to flow from one electrode 12 to the other electrode 13. Since the buried electrodes 12 and 13 are united in one body, the electrodes are excellently adhered to both surfaces of the film 11 and insulating oil hardly intrudes along the interfaces between the electrodes 12 and 13 and film 11. At the same time, no cleaning process is required. Therefore, highly reliable measured results can be obtained.

Title: Sheet feeding mechanism for perfect image forming device
Inventor: NISHIHAMA HITOSHI
IPC: B65H1/30
Filed: 1987-08-10
Abstract: PURPOSE:To prevent jamming or oblique formation of image by arranging a stopper for stopping the tip of a sheet being carried and correcting the direction of the sheet in the way of a through which the switched back sheet is carried to an intermediate tray. CONSTITUTION:When a sheet is switched back obliquely, preceeding portion of the tip of the sheet collides against a stopper 1. The preceeding portion of the sheet is subjected to static frictional force of the stopper 1 and stopped there at a moment. Since the sheet is fed continuously by a second carrying roller 3 during this moment, the sheet is further bent resiliently and other portions of the tip of the sheet arrive to the stopper 1 subsequently. In such a manner, the tip of the sheet can be arranged. Consequently, jamming and oblique formation of image can be prevented.
