Title: Laminated inductance element and its manufacture
Inventor: KATAOKA MITSUMUNE
IPC: H01F41/04
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To increase the Q-value of a laminated inductance element in which a spiral or meandering-shaped conductor coil is provided in a nonmagnetic ceramic layer by using metallic foil as the conductor of the coil. SOLUTION: After a green sheet having a thickness of 200 μm is formed of nonmagnetic ceramic forming paste (paste) by the doctor blade method, a laminated winding which becomes an inner conductor is formed in the nonmagnetic ceramic layer of the green sheet. Then Ag foil is laminated upon another Ag foil by printing and sticking the foil upon another foil by hot- pressing the foil to a prescribed shape by using the paste and Ag foil stuck to a plastic film substrate and having a thickness of 10 μm. After the printed laminated foil is obtained, the green sheet having the thickness of 200 μm is superposed and laminated upon the printed laminated foil by using the paste and, after the laminated body is cut to a prescribed size and the used binder is removed, the laminated body is baked.  Thereafter, a laminated inductance element is manufactured by forming external electrodes by applying conductive paste to the surface of the baked body on which the leads of the laminated winding are exposed and baking the paste.

Title: Toner jet type image recorder
Inventor: KITAMURA TETSUYA
IPC: B41J2/385
Filed: 1990-07-23
Abstract: PURPOSE:To prevent the positions of toner images from being deviated by including first toner and second toner, which are mutually electrostatically charged to reverse polarity, in a toner supply part and constituting a toner passage part so that the first toner or the second toner is allowed to be passed through the toner passage part by an impressed electric field. CONSTITUTION:The toner supply part includes the first toner 21 and the second toner 22 which are mutually electrostatically charged to the reverse polarity, and the toner passage part allows the first toner 21 or the second toner 22 to be passed through the toner passage part by the impressed electric field. That means, the first toner 21 or the second toner 22 in the toner supply part which are mutually electrostatically charged to the reversed polarity is passed through the toner passage part and attached on a recording member. Thus, since the first toner image 23 and the second toner image 24 are formed at one place on a supporting body, the positions of the respective toner images are not deviated.

IPC: G06T1/00
Filed: 1981-12-07
Abstract: PURPOSE:To sort hemocytes with high accuracy and high efficiency, by isolating and flowing the hemocytes in the diluted blood one by one, measuring the light absorbing degree and the light diffusing degree of the hemocytes and detecting and storing a color video signal at the downstream, if necessary. CONSTITUTION:The diluted hemocytes dyed with a dyeing agent are injected 10, and each hemocyte 16 is isolated through a nozzle 12 of a sheath flow to be flowed inside a tube 14. The light of a light source 22 is condensed 24 and irradiates the hemocyte 16. Then both the transmitted light and diffused light are obtained for R, G and B respectively through a light absorbing degree detector 26 and a light diffusion detector 28 and then fed to an analyzing/selecting circuit 30 to complete a sorting process at that time point. If the sorting is impossible, a timing circuit 46 closes a switch 44 to reflect 36 the light of the source 34 when the hemocyte 16 reaches the 2nd device 32. The three line sensors 38 for R, G and B deliver the video signals. These video signals receive an A/D conversion via the switch 44 and then stored 40 to be displayed to a CRT48 for analysis. In such a way, the hemocytes can be sorted with high accuracy and high efficiency.

Then a stepping motor 19 is driven via a motor driver 15 to adjust the picture read position when viewing from the CCD 8. Thus, the read position by the solid-state image pickup element 8 is always made the same point.

Title: Blower motor controller of hot air type heater, etc.
Inventor: SEKIDO KENJI
IPC: H02P27/02
Filed: 1993-08-09
Abstract: PURPOSE:To obtain the intermediate number-of-rotations by applying alternately 1/n cycle-cut voltage and 1/(n+1) cycle-cut voltage. CONSTITUTION:An AC supply voltage waveform which is input from an AC power supply input terminal IN and then is passed through a transformer 1 is converted into a pulse row by a zero cross pulse generating circuit 2 and then is input to a microcomputer(MC) 3. In the MC 3, the control of a blower motor 6 is conducted every other time. A counter counts the number of settings 'n' for a waveform cycle of the AC power supply voltage every time the motor is controlled and detemines if the counted number is a specified one or not and then outputs a square wave signal that has one less cycle than the set ones. When the number of cycles is set in the counter, the flag condition is judged and the number of cycles 'n' and 'n+1' are alternately set in the counter. Therefore, the MC 3 outputs alternately 1/n cycle-cut waveforms that has the one less cycle than 'n' and 1/(n+1) cycle-cut waveforms that has one less cycle than (n+1).

Abstract: PURPOSE:To simplify a job for vertical drilling by setting up a pair of horizontal crank ballancers in a drilling unit quipped with an on-off shovel, while installing a vibromotive device equipped with a rotatory driving means which rotates this balancer concentrically. CONSTITUTION:A hydraulic cylinder 18 of a drilling device is driven, and, after a shovel 14 is opened of its legs and vertically set in the ground, a rotary sleeve 20 is rotated, rotating a shaft 12. Next, when a vibromotive device's motor is driven, a pair of crank balancer is simultaneously rotated in the opposite direction, and inertia force by a pair of eccentric blocks is compounded in the axial direction of the shaft 12, thus vibromotive force is generated. In succession, the shaft 12 vertically moves, while the shovel 14 vibrates up and down, thereby digging the ground down vertically. In this case, if it is reached to the specified depth, the legs of the shovel 14 are opened to some extent, then these legs are pulled up to the ground in a state of having pinched the digged earth and sand.
