Title: Cleaning device for image forming device
Inventor: HISAKUNI HISATAKA
IPC: G03G21/10
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent an image carrier from being damaged due to aggregation and excessive supply of toner and to stably keep an excellent cleaning function over a long period by providing a means for disentangling the toner retaining in a toner carrying means. SOLUTION: The toner scraped by a cleaning blade 3 is carried toward a toner reservoir part 8 by a scooping sheet 4 and a stirring member 5 and while being attracted to the stirring member 5, and toner on a sheet side is carried, by a magnetic field generating means 6 provided in the stirring member 5. As the fetching of the toner by the magnetic field generating means 6 at this time, the forced fetching of all the toner in a related position, like stirring by the blade parts of the stirring member 5 is not executed but the toner is attracted/fetched in an irregular state by the strength and weakness of magnetic force exerted on the toner, so that mechanical force such as shaking is exerted on the toner in this part, to disentangle the flocculated toner and prevent concentration from being high.

Title: Ophthalmologic apparatus
Inventor: SUZUKI TAKAYOSHI
IPC: A61B3/10
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of presenting desirable observation of interference pattern by emphasizing contrast of the interference pattern formed by the tear layer in the front of examined eye. SOLUTION: A straight polarizing plate 5 is put in a lighting system to light up the front of examined eye P. As the light irradiated to the tears layer of the cornea P becoming straight polarization elements 5a parallel to a paper face, reflected light from the front and back face of the tears layer presents much more interference so as to form a highly contrasted interference pattern made of identically directional polarization. The interference pattern is received by a CCD camera 8 through another straight polarizing plate 7 having a polarization axis same with that of the straight polarizing plate 5. The contrast of the interference pattern is emphasized so as to assure an accurate diagnosis of the tears distribution on the examined eye as the interference pattern shot by the CCD camera 8 contains much more AC elements and less DC elements which have no effect to the interference.

Title: Dc power circuit
Inventor: KAKIMOTO KOJI
IPC: H02J1/00
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a DC power circuit consisting of a DC-DC converter in an electronic device which ensures stable start-up using a simple and inexpensive control circuit without increasing current capacity for feeding or using an expensive and complicated rush current suppressing circuit. SOLUTION: A rush current suppressing circuit 1 consisting of transistors Q1, Q2, and resistors Rc, R1-4 is inserted between DC power supply E and a capacitor Cin. If excessive input current is flowed at the time of starting up the power supply, an appropriate potential difference is generated at both ends of the resistor Re to turn on Q1 and push up Q2 base potential, thereby tuning off Q2. Therefore, the current from the DC power supply E is not supplied to a subsequent stage, the DC-DC converter circuit 2. When the input current recovers to a steady state, Q1 is turned off, Q2 is turned on, and the current is supplied to the DC-DC converter circuit 2 to start up the DC-DC converter circuit 2. Setting the resistor Re in the rush current suppressing circuit 1 permits suppressed current which turns off Q2 to be determined.

Filed: 1993-07-21
Abstract: PURPOSE: To obtain a very small machine capacitor which provides a linear capacitance change to acceleration by providing a section which can move freely in the horizontal direction to a dither coupled with anchors attached to a substrate. CONSTITUTION: An level sensitive accelerator is constituted of anchors 12 attached to a substrate, a dither 13 having a section which freely moves in the horizontal direction in response to acceleration, tie bars 14, and a plurality of mobile capacitor plates 16. The number of the plates 16 is selected so as to meet individual applicable basis, such as the sensitivity, size restriction, linearity, etc. The main capacitance generated from this accelerator is generated by means of a fixed capacitor plate together with the plates 16. The capacitance change is not caused by such a general method as the change of separation between the capacitor plates, but the areal change of a capacitor, and becomes a linear function. Therefore, this accelerometer substantially has a linear output against the acceleration.

Title: Four-cycle engine
Inventor: KINOSHITA TOSHIKAZU
IPC: F02B29/00
Filed: 1981-12-12
Abstract: PURPOSE:To ignite an air-fuel mixture layer under a high pressure by introducing the air into a cylinder through an air hole immediately before a piston reaches a bottom dead point. CONSTITUTION:When an intake valve 1 is opened, a fresh air-fuel mixture is sucked into a cylinder 5. As a piston 3 approaches a bottom dead point, an air hole 6 is opened, and the air is sucked through the air hole 6 because of the negative pressure in the cylinder 5. The upper section in the cylinder 5 is filled with the air-fuel mixture and the lower section is filled with the air. When the piston 3 is raised, both the air-fuel mixture and the air are compressed, but the pressure in the cylinder 5 becomes higher by an amount of the air layer compared with a conventional four-cycle engine.
