Inventor: HATANAKA HIROSHI
IPC: H01P1/205
Filed: 1994-05-26
Abstract: PURPOSE:To realize the band pass filter in which its inter-stage coupling is made by either of magnetic coupling and capacitive coupling and its coupling coefficient is varied without changing a center-interval of resonance elements with excellent productivity and also to realize the multicoupler employing the band pass filter. CONSTITUTION:An inter-stage coupling capacitive element is provided among resonance elements 41-44 arranged side by side in each common dielectric block 2 and whose inter-stage coupling is substantially magnetic coupling. The impedance of an inter-stage coupling parallel resonance circuit comprising the capacitance of the capacitive elements and the equivalent inter-stage coupling inductance of the resonance elements 41-44 arranged side by side is inductive for a frequency band lower than the resonance frequency, and the inter-stage coupling is magnetic coupling and the magnetic coupling coefficient is varied by changing the capacitance of the variable capacitive element. Furthermore, the impedance of the inter-stage coupling parallel resonance circuit is capacitive at a frequency band higher than the resonance frequency, the inter-stage coupling is capacitive coupling and the magnetic coupling coefficient is varied by changing the capacitance of the variable capacitive element.

Title: Wire dot printer
Inventor: SAWADA SHIGETOMO
IPC: G06K15/10
Filed: 1978-11-06
Abstract: PURPOSE:To check the generation of leaked magnetic flux by enabling simple and proper adjustment of the amount of flux by means of a small hole for magnetic  resistance formed in the sub-magnetic path composing a yoke. CONSTITUTION:When excited, an electromagnet 6 receives an excitation opposite to a permanent magnet 5 and the magnetic flux generated from the permanent magnet 5 is diverged into a suction part 2 and a side current part 7 causing decrease in the flux of the suction part. Consequently, an armature 4 is released by force of a spring 1 and a printing wire 9 impacts on the surface of the recording paper so as to effect printing. In an apparatus of such a type, a small hole 10 for magnetic  resistance is provided on the side current part of a yoke 3 for example at the angle  of flux flowing to the section. With such an arrangement, the amount of flux flowing through the main and submagnetic paths can be adjusted simply and properly.  This checks the generation of leaked magnetic flux eliminating adverse effect on the adjacent head thereby stabilizing actions.

Abstract: PURPOSE:To provide a pack cosmetic which can be removed without washing, can be dried in a short time, and can form a dried film giving moderate astringent feeling to the skin, by adding crystalline cellulose to a peel-type pack containing an alginic acid salt. CONSTITUTION:The objective pack cosmetic can be obtained by reacting a water-soluble alginic acid salt (e.g. sodium alginate) with >=2-valent metal salt (e.g. calcium citrate) in the presence of water, and mixing the resultant film- forming gel of metal alginate (e.g. calcium alginate) with crystalline cellulose (microcrystalline cellulose powder). The amount of the water-soluble alginic acid salt, the >=2-valent metal salt and the crystalline cellulose are preferably 5-20pts.wt., 15-35pts.wt., and 45-70pts.wt., respectively. When the >=2-valent metal salt is a highly reactive salt such as calcium sulfate, etc., it is preferable to add 0-8pts.wt. of an alkali metal salt as a reaction regulator to suppress the gelling reaction.

Title: Magnetic bubble memory device
Inventor: YOSHIDA KAZUTOSHI
IPC: G11C11/14
Filed: 1982-08-09
Abstract: PURPOSE:To ensure the operation of a magnetic bubble memory device despite replacement of magnetic bubble memory elements of different capacities, by storing a constant into a magnetic bubble memory element itself. CONSTITUTION:When the data of a map loop 8 (shown in the figure) is read out, the replicator pulses are consecutively flowed to a replicator 10 for map loop as shown by (a) in the figure. Then magnetic bubbles written into the loop 8 are successively read out and shifted to a line 3. At the same time, strobe pulses shown in the figure (b) are applied continuously to detect magnetic bubbles. In this case, a prescribed number of bits is needed to transfer the magnetic bubbles from the position of the replicator 10 through the position of a detector 7. Therefore the output of the detector 7 is kept at ''0'' for a period during which the replicator pulses are flowed to the replicator 10 and the head data reaches the detector 7. In the figure, the solid lines show ''1'' (presence of bubble) and dotted lines show ''0'' (absence of bubble) among magnetic bubble outputs.

Title: Ion pump power source
Inventor: IZUMI EIICHI
IPC: H01J41/12
Filed: 1982-08-09
Abstract: PURPOSE:To improve the operationability while to automate the evacuating operation, by producing the starting pulse with predetermined period only when a drive signal is inputed while detecting the ion pump state after each pulse and stopping the drive signal when it is under blocked state. CONSTITUTION:Upon input of a start signal to a block circuit 7 of a high voltage generating circuit 6, an ion pump 1 will start but if excessive current IC will flow due to insufficient preliminary exhaust, the voltage across a detection resistor 2 is detected by a detector 3 and a comparator 5 to provide a blocking signal to the blocking circuit 7 thus to stop the pump 1. On the other hand, the starting signal will constitute a logical sum by passing the output signal from an operating circuit 10 and a pulse from a pulse generator 9 through gate 8 thereby even if the pump 1 has stopped, the starting pulse is produced again through pulse synchronization thus to start the ion pump. A counter circuit 11 will count the starting pulse, and if the block circuit 7 is under blocked state at predetermined count the gate 12 will block the operating circuit 10.

Title: Corrosive permanent magnet
Inventor: TANIGUCHI MASAAKI
IPC: C22C38/00
Filed: 1989-05-30
Abstract: PURPOSE:To enable the film thickness of a protection layer to be uniform, to reduce residual stress, and improve corrosion resistance by providing an N-P alloy protection layer in two-layer laminated state of different P content in amorphous structure which is formed on the surface of a sintered permanent magnetic body by the electroless plating method. CONSTITUTION:An R (R is one or more types of rare-earth elements including Y)-Fe-B family is used as a sintered permanent magnet body 2. A protection layer 3 is formed by the electroless plating method. The protection layer 3 by the electroless plating method changes from a crystal to an amorphous as the content of phosphor increases and becomes nearly perfect amorphous structure with phosphorus being equal to or more than 8wt.%. Then, in the case of the protection layer 3 in amorphous structure, there is no regularity in the growth direction of crystal, thus enabling it difficult to generate pin holes. In the sintered permanent magnetic body 2, an electroless deposition reaction is hard to occur within an acid solution and a first layer 3a with less content of phosphorus is formed using an alkali plating bath (pH7 or more). With pH of the plating bath being 6.5 or more, a complete amorphous structure is formed as a second layer 3b.
