Title: Two-layer flexible printed circuit substrate and its manufacture
Inventor: YAMAMORI YOSHIYUKI
IPC: H05K1/03
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To readily obtain a highly reliable two-layer flexible printed circuit board in a mild condition by forming a male imide resin layer comprising a repeating unit expressed by a specified formula directly on a conductor foil surface. SOLUTION: A maleimide resin layer comprising a repeating unit expressed by a formula is formed directly on a conductor coil surface. In the formula, each of R1, R2 expresses one kind selected from a group consisting of hydrogen, alkyl group, phenyl group and displaced phenyl group and they can be the same or different from each other. R1 expresses a dihydric aromatic group. Since male imide resin is excellent in flexibility, it can be extremely readily adjusted by a mild process at a low temperature by using monomer mixture of easy-to-handle powder as a starting substance. Therefore, a two-layer flexible printed circuit board can be readily manufactured by using the maleimide resin solution.

Abstract: PURPOSE:To enable the suppression of the occurrence of an iron loss irrespective of the material of the armature core of a motor and to prevent the pulsation of the rotating torque of the rotor of the motor by forming a structure that the armature core and the rotor are integrally rotated and the relative position between the core and the rotor does not vary. CONSTITUTION:A cylindrical armature core 14 is so formed as to be disposed concentrically with field poles 9 from a rotor yoke 7 and to be integrally risen and is disposed within the air gap 11d of a bobbin 11. Eight valleys 14a are formed on the outer peripheral surfce of the core 11, extend elevationally, eight edges 14b are confronted with the magnetic neutral point 9a among the magnetic poles 9, the width of the air gap 15 is thus circumferentially altered, and is minimized at the neutral point 9a. Thus, the magnetic flux density at the gap 15 can be varied in trapezoidal wavy shape and can be maintained constantly regardless of the rotating position of the rotor 4. A driving circuit 18 then energizes the armature coil 13, thereby producing a torque between the coil 13 and the magnetic poles 9 and rotating the rotor 4 in a predetermined direction.

Title: Drive circuit for motor
Inventor: SAITOU MIKITO
IPC: H02P1/16
Filed: 1983-04-08
Abstract: PURPOSE:To prevent a motor from vibrating at the starting time by inputting the difference between an input control voltage and a drive output voltage to a mirror integrator, increasing the rising integrating time constant and decreasing the falling integrating time constant by a unidirectional element. CONSTITUTION:When an input voltage Vin rises to the prescribed positive level, the output voltage of a voltage comparator VC becomes negative in the rotation stopping state. Accordingly, a diode D is reversely biased to the negative voltage to become OFF state, and the output voltage Vout of an operational amplifier OP rises in accordance with the time constant of resistors VR and R1 and a capacitor C. When the input voltage Vin falls at the prescribed time constant, the output voltage of the voltage comparator VC is inverted to form a positive voltage. Accordingly, the diode D becomes ON state. Consequently, at this time the output voltage Vout falls in accordance with the time constant of the capacitor C and the resistor R2.

Title: Discharge lamp lighting device
Inventor: MITA KAZUTOSHI
IPC: H05B41/24
Filed: 1994-03-30
Abstract: PURPOSE:To surely release the action of a latch circuit at the time of detaching a lamp by a simple and inexpensive constitution by supplying a power source to be given to a latch circuit from the potential divided point of a capacitor connected in parallel with the switching element of a high frequency inverter. CONSTITUTION:When the oscillation action of a high frequency inverter circuit 7 is normal, current flows between both terminals of capacitors C8 and C9, but when a load is released such as a lamp is detached, D.C. voltage is applied to make no current flowing. Consequently, in the intermediate connection point A between the capacitors C8 and C9, the D.C. electric potential of an H/L level is generated in accordance with the presence/absence of the oscillation action of a transistor 4. When the electric potential at the point A is used as the power source of a latch circuit 9, normal latch action is performed usually in the circuit 9, but when the oscillating transistor 4 stops oscillation, electric potential at the point A becomes nearly zero V to release the latch circuit 9. This surely release the performance of the circuit 9 at the time of detaching a lamp by simple and inexpensive constitution without adding a special latch release circuit.

Title: Electronic camera having consecutive photographing function
Inventor: HAYASHI MASAKI
IPC: H04N5/91
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To increase the consecutive photographing speed by compressing an image via the setting of a high compression rate if the resolution is set at a low level and converting the resolution via the setting of a low resolution level if a high compression rate is set at the high compression side when the consecutive photographing is performed. SOLUTION: When a fast consecutive photographing operation is started, a CPU 16 reads the image data out of a CCD image pickup element 13 via a CCD drive circuit 13a and outputs the image data to an image processing circuit 15 after digitizing them via an A/D converter 14. The circuit 15 temporarily stores the image data in a memory 18. Then the circuit 15 lowers the resolution of the image data stored in the memory 18 regardless of the resolution mode that is previously set and then compresses the image data at a high compression rate regardless of the compression mode that is previously set. Thus, the consecutive photographing speed is increased with higher assuredness.

Title: Encoding device
Inventor: SHIRAISHI YOSHINORI
IPC: H03M7/46
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To quickly realize encoding processing in image data, in which plural changing points are present without depending on the operating clock of a device by inputting an image data stream of m bits, and outputting pixel changing points at which pixels are changing, and inputting and decomposing this output into the maximum n pieces of runs. SOLUTION: A changing point detecting circuit 1 detects the changing points of pixels from an image data stream of m bits from an inputted 0-th bit to (m-1)-th bit, and outputs the changing point data. A run decomposing circuit 2 inputs the changing point data from the changing point detecting circuit 1 and decomposes the image data stream of m bits having the maximum n pieces of changing points into the maximum n pieces of runs, and outputs the run decomposed data. A run length calculating circuit 3 inputs the run decomposed data from the run decomposing circuit 2, and calculates the maximum n pieces of run length in parallel. Thus, once the changing points of the pixels are detected, the image data stream is immediately decomposed into m×n matrix run, so that the run length of white pixels or black pixels can be calculated at high speed.

IPC: B29D30/32
Filed: 1981-04-24
Abstract: A bead bundle positioning mechanism is provided to accurately locate one axial surface of each bead bundle prior to radial expansion of the tire carcass. Each bundle (62) is held by a plurality of circumferentially spaced clamping mechanisms (10) each of which has a pair of clamping elements (40, 48) respectively engaging the axially inner (68) and axially outer (72) surfaces of the bead bundle (62). The axially inner surface (68) of each bead bundle (62) is located by respective clamp members (40, 48) which are adapted to cooperate with a tire building machine to provide a predetermined axial distance between the bead bundles during tire assembly while also maintaining the inner axial surfaces in parallel planes which are normal to the longitudinal axis (15) of the tire building drum (74). The inner and outer clamping elements (40, 48) are actuated by independent fluid motors (34, 36). The clamping force exerted by the axially inner clamping element (40) is greater than the clamping force exerted by the axially outer clamping element (48), to insure that the axially inner surface (68) of the bead bundle (62) is the referenced positioning surface. The inner clamping element (40) interacts with a stop member (42) to establish a predetermined position for the axially inner surface (68) of the bead bundle (62).

Abstract: PURPOSE:To avoid the destination of stored data by a method wherein a memory cell is formed in an exclusive well to be electrically insulated from the well for a peripheral circuit. CONSTITUTION:A p type well 13 for a peripheral circuit 2 and another p-type well 23 for a memory cell array part 3 are electrically insulated from each other so that, even if electrons are injected in the p type well 13 from the source of an n MOS transistor 16 to fluctuate the potential in the p type well 13, the p-type well 23 may not be affected by the fluctuation at all thereby enabling the destination of the stored data due to the pn junction between a storing electrode 34 and a p-type well 23 reaching the bias state in the normal direction to be avoided. Besides, in case a cell plate voltage is lowered by lowering an inner power supply voltage Vint, the potential in the p-type well 23 is lowered interlocking with the cell plate potential Vpr so that the pn junction between the storing electrode 34 and the p-type well 23 may not reach the bias state in the normal direction thereby enabling the backward bias to be sustained. Accordingly, the destruction of the stored data can be avoided.
