Title: Animal model for renal osteodystrophy
Inventor: HIGAKI HITOSHI
IPC: A01K67/00
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To obtain an animal model for a renal osteodystrophy by administering adenine, capable of simply and easily producing, and suitable for confirming a therapeutic effect on the renal osteodystrophy. SOLUTION: This animal model for a renal osteodystrophy is obtained by e.g. orally administering a feed containing approximately 0.75wt.% adenine of an animal origin, etc., for one month or more to a rat aging 4-10 weeks. Also, since the number of survival days of the model rat for the renal osteodystrophy is prolonged by administering the adenine by changing its amount to such as 0.50 or 0.25wt.% after administering the feed containing 0.75wt.% adenine for one month, it is preferable to decide a dose in accordance with the purpose and period of the test.

Title: Fly-back converter
Inventor: HAYASHI MASAAKI
IPC: H02M3/28
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply capable of reducing power consumption and noise. SOLUTION: When a DC power supply 1 and a control power supply 6 are turned on, an 'on' signal from an IC control device 18a is outputted to turn on MOSFETs8, 15 in a drive circuit and to turn off a MOSFET 12. By turning on the MOSFET15, a dropper 17 supplies a charging current to a gate input capacitor of a MOSFET12 through the MOSFET15, a high-speed diode 14 and a resistor 13, which makes the gate-source voltage of the MOSFET2 slightly higher than a threshold VTH of the MOSFET2 and turns it on. Also, by turning on the MOSFET8 at the same time, the dropper 17 supplies the charging current to the gate-source parastic capacitor of the MOSFET2 through the MOSFET8 and a constant current circuit 9 and as time elapses, the gate-source voltage of the MOSFET2 rises.  As a result, it is possible to supply the gate-source voltage of the MOSFET2 proportional to its drain current, that increases with time after it is turned on.

Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To reduce a camera-shake correction residual component due to temperature fluctuation or a change with respect to passage of time in a camera- shake sensor. SOLUTION: The camera is made up of a camera-shake correction signal generating means 40, receiving sensing output from a camera-shake sensor 18 fitted to a camera main body, a camera-shake correction means 22 receiving the camera-shake correction signal, a calibration signal generating means 36 receiving biaxial shake signals Sx, Sy obtained by picking up an image of a test pattern 24, a gain adjustment means 38 that adjusts a gain of the sensing output based on a calibration signal Sc. The gain of the gain adjustment means is adjusted based on the calibration signal Sc, so that the biaxial signals obtained by picking up the image of the test pattern 24 approaches unlimitedly zero.  Since the biaxial signal component includes a fluctuation component of a sensing output due to a temperature fluctuation or a with respect to passage of time change in the camera-shake sensor, the camera-shake correction residual component due to the fluctuation component of the sensing output due to the temperature fluctuation or the with respect to passage of time change in the camera-shake sensor is reduced through the calibration processing.

Title: Laminated ceramic component
Inventor: SHIMIZU SHIGEAKI
IPC: H05K1/09
Filed: 1988-12-06
Abstract: PURPOSE:To obtain a laminated ceramic component using stable and inexpensive inner electrode material by employing titanium boride powder as a powder material for conductive paste. CONSTITUTION:Titanium boride (TiB2) power is employed as a powder material for conductive paste. The oxide of the titanium boride at the time of sintering remains on its surface layer, and is not completely oxidized. Accordingly, electric conductivity equivalent to that of pure metal of original material can be maintained to a certain degree, and function as an inner electrode can be obtained even after sintering. Thus, a laminated ceramic component which is much inexpensive, stable and excellent reliable as compared with a conventional silver-palladium alloy can be obtained.

Filed: 1992-11-20
Abstract: PURPOSE:To prevent electronic components from inclination toward one side when packed in a case by a method wherein the electronic components are attached to tape in the longitudinal direction with the terminal pins thereof secured to both the sides of the tape. CONSTITUTION:A mount paper 5 and an adhesive paper 4 having its side opposite to the mount paper coated with adhesive are set on a pair of rollers to securely hold the terminal pins 3 of LED 1 between the mount paper 5 and the adhesive paper 4 at predetermined intervals. During this operation, a series of LED's 1 are secured to each side of the tape 6 and the two LED's 1 are arranged in laterally aligned pair between each adjacent hole 7. When a case is packed with the tapes, the difference in the thickness of the tape between its sides resulting from the overlapping of electronic components is almost completely eliminated by the afore-said electronic component arrangement, thereby realizing a radially taped electronic component which, in the case, is prevented from inclination toward one side and from the looseness tending to cause damage thereto.
