Title: Photosensitive lithographic printing plate
Inventor: SHIBA KEISUKE
IPC: G03F7/00
Filed: 1986-02-25
Abstract: PURPOSE:To obtain an inexpensive photosensitive lithographic printing plate by providing an adhesive agent layer and layer which is a layer of particles having the surface to be converted to hydrophilicity by a developing process and is tightly adhered to the adhesive layer on a base and providing a layer of a photosensitive compsn. on the layer of the particles. CONSTITUTION:The layer of the particles to be provided on the adhesive agent layer is constituted of the particles consisting of a material which has a relatively hydrophobic surface but is converted to hydrophilicity by the developing process. The material having such characteristics is exemplified by solid powder of amphoteric org. oxides of the atoms selected from the groups 2, 3 and 4 of periodic table. The solid particle is stuck to a laminar state on the adhesive agent layer before the adhesive layer completes curing at the time of forming the particle layer on the adhesive agent layer. After a reaction type adhesive agent is coated on a base, the particles are applied on the adhesive agent layer and the adhesive agent is brought into reaction to adhere the particles, then, the unadhered particles are removed and thereafter the photosensitive compsn. is coated on the particle layers. The inexpensive photosensitive lithographic printing plate is thus obtd.

Title: Frequency converter
Inventor: HIROSE MASAAKI
IPC: H03C1/58
Filed: 1980-03-31
Abstract: PURPOSE:To miniaturize the structure and to convert a wide signal frequency into a desired high frequency with a constant conversion loss, by performing the frequency conversion by using a magnetic resonating element and diode ring. CONSTITUTION:At the terminal of coaxial line 3, unbalanced/balanced converting circuit (balloon) 4 is formed. Connection points 9 and 10 of diode rings 5-8 connected together successively in an annular shape with the same polarity are connected to output terminal of circuit 4, and both terminals of input coupling line 13 are connected to connection points 11 and 12. Line 13 forms the coil of the primary winding and in it, high-frequency magnetic resonating element (spherical YIG)14 is arranged. So that a magnetic field provided by line 13 is at right angles in element 14, a DC magnetic field is applied. Thus, low-pass filter 1 prevents local oscillation outputs, applied to diode rings 5-8, from leaking from line 13 to a signal source. In addition, since line 13 and output coupling line 16 are at right angles,  neither an input signal nor an output of local oscillation frequency is induced at line  16.

IPC: G09F11/23
Filed: 1990-02-23
Abstract: PURPOSE:To strengthen a magnetic force working on a permanent magnet which is integrally disposed with a rotor, to restrain the positional deviation at the time of rotating and the vibration at the time of stopping rotation by forming the magnetic poles of electromagnets so that they may be in a fan shape enlarging at nearly 90 deg. on a flat plane which is orthogonally crossed with a rotating axis. CONSTITUTION:The magnetic poles 19a, 19b, 20a and 20b of the 1st and the 2nd electromagnets 19 and 20 are formed so that they may be in the fan shape enlarging over the extent of the angle at nearly 90 deg. on the flat plane which is orthogonally crossed with the rotation axis 14. In the case of viewing around the rotation axis 14, nearly intermediate positions between the right and left edges of two magnetic poles 19a and 19b of the 1st electromagnet 19 and between the right and left edges of two magnetic poles 20a and 20b of the 2nd electromagnet 20 respectively become magnetically stabilized positions, so that four stable positions at the intervals of 90 deg. around the rotation axis 14 can be obtained. When the electromagnets 19 and 20 are excited so that the rotor 14 may be rotated to a desired position, the attracting force and the repulsive force from the magnetic poles 19a and 19b and the attracting force and the repulsive force from the magnetic poles 20a and 20b respectively work on the 1st and the 2nd permanent magnets 17 and 18. Thus, the vibration at the time of stopping rotation can be restrained.

IPC: B22C3/00
Filed: 1993-03-02
Abstract: PURPOSE:To effectively catch a large quantity of decomposed gas or liquefied product generated from a lost foam pattern, to realize quick substitution for metal and to obtain a good quality casting. CONSTITUTION:In the case of this lost foam pattern casting method, a porous material layer 5 is formed on the outer surface of a facing agent layer 3.
