Patent JP-H0250457-A (JP)
Title: Programmable logic array
Inventor: USAMI MASAYOSHI
IPC: H01L21/82
Filed: 1988-08-12
Abstract: PURPOSE:To realize high speed operation and reduce the power consumption by a method wherein a clock frequency is increased by using a one-phase clock and DC currents are not applied during the precharge period of MOS transistors in an AND plane and an OR plane. CONSTITUTION:A one-phase clock phi is directly applied to the gate electrodes of first group MOS transistors P10-P12 and An inverse input of the one-phase clock phi is applied to the gate electrodes of second group MOS transistors P13 and P14. Thus, a clock frequency is increased by using the one-phase clock phiand, at the same time, DC currents are not applied during the precharge period of MOS transistors N11-N18 in an AND plane and an OR plane. Therefore, only precharge currents and discharge currents are applied to product lines l1-l3 in the AND plane or output lines l8 and l9 in the OR plane and steady state currents are not applied. With this constitution, high speed operation can be realized and the power consumption can be reduced.

Title: Intermittently feeding device
Inventor: ASAKA URATARO
IPC: F01M1/02
Filed: 1987-08-13
Abstract: PURPOSE:To simplify and lighten a device, improve a following property, facilitate installation and replacement, and prevent the generation of noise by forming a feed claw and a stopper claw in a forked simple structure by the use of a long and narrow leaf spring. CONSTITUTION:The inner pressure of a crankcase is introduced into a diaphragm 22 after being regulated through a pressure regulating circuit 21 and is taken out by the diaphragm 22 as a reciprocating power to reciprocate a push rod 25. Then, a feed claw 26 engaged with the rod 25 is rotated by a defined angle with its end being hooked on a ratchet wheel 17 by means of the rod 25 and, then, when the rod 25 is continuously shifted to retraction, a stopper claw 27 stops the ratchet wheel 17 with its end being hooked on it. Thus, by repeating these operations, the reciprocation of the rod 25 is converted into the one-way intermittent rotation of the ratchet wheel 17. The feed claw 26 is formed into a hair pin shape with a long and narrow and thin- walled leaf spring to be removably engaged with the rod 25, while the stopper claw 27 is formed into a fork shape with a long and narrow and thin-walled leaf spring, so as to bring a stopper piece 27b into contact with the ratchet wheel 17 while bringing a contact piece 27c into contact with a casing 10.

Abstract: PURPOSE:To attain the operation at a high speed clock by providing a transfer gate for equalization turned on/off with a control signal synchronously with a clock signal and short-circuiting a complementary output so as to bring a complementally output of a latch circuit to a level between an H and an L level.

Title: Brake control device
Inventor: HARADA ISAMU
IPC: F16D65/14
Filed: 1990-07-30
Abstract: PURPOSE:To get a compact size brake control device by providing a brake enforcing action controlling means which increases gradually the enforcing action of a brake spring or keeps it constant when a brake lever is moved to a brake releasing position through drive of a cylinder. CONSTITUTION:When a cylinder 15 is driven so as to release a brake, its output is transmitted to a first crank lever 9 through a spring 22. Then, the first crank lever 9 rotates in the brake releasing direction and, at the same time, a brake lever 6 moves to the brake releasing position and a brake device 3 comes in the brake releasing state. Furthermore, when the first crank lever 9 rotates in the brake releasing direction, a second crank lever 24 is rotated in such a direction that the enforcing action of a brake spring 25 increases gradually or is kept constant by means of a brake enforcing action controlling means 28. Thus, remarkable increase of the enforcing action of the brake spring 25 in the braking direction does not occur during releasing the brake. Consequently, it is possible to make the amount of extension/contraction of the brake spring 25, small than the displacement of the first crank lever 9 connected to the brake lever 6.

Abstract: PURPOSE:To reduce the variance of a measured value due to temperature and that due to the variance of the precision of parts by using a time ratio of the time before crossing between a comparison voltage and a measured voltage to the time before crossing between the comparison voltage and a reference voltage and the reference voltage value to calculate an A/D conversion value of the measured voltage. CONSTITUTION:Charging is started in a constant current charging circuit 2 by the charging start signal from an A/D converting and signal processing part 1, and the comparison voltage of comparators 3 and 4 is linearly raised, and simultaneously, time counting is started in time counting parts 5 and 6. The comparison voltage is compared with a measured voltage V1 and a reference voltage V2 by comparators 3 and 4, and a time t1 when the measured voltage V1 exceeds the comparison voltage is counted by the time counting part 5, and this time counting is stopped when the comparison voltage exceeds the measured voltage V1. Similarly, only a time t2 when the reference voltage V2 is higher than the comparison voltage is counted by the time counting part 4. Counted values of time counting parts 3 and 4 are operated in an A/D conversion value correcting and calculating part 7 after a certain time, and the measured voltage V1 is obtained in accordance with V1=V2Xt1/t2.

Title: Method and device for outline font generation

IPC: G06T11/20
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To simply obtain outline fonts from bit map fonts by considering the bits, which are continuously turned on in a lateral direction in bit map fonts, as a rectangle and converting it into special coordinate values. SOLUTION: Bit map fonts, which are the subject of the conversion, are constituted by m×n bits in the longitudinal and lateral directions, respectively. The bits, which are continuously turned on, being more than one, in the lateral direction of the bit map fonts, are considered as one rectangle and the position of the bit in the lateral direction located at the tip section of the rectangle is obtained. Then, the position of the bit in the lateral direction located at the other tip section of the rectangle is also obtained. Moreover, the position of the rectangle in the longitudinal direction is obtained. The coordinates of the four apexes of the rectangle are computed from the information obtained above for the position of the rectangle.  By repeating the processes above, one rectangle is arranged in the same position as a figure 'a' shown within the coordinate system having the size of M×N in the longitudinal and lateral directions, respectively. Thus, the rectangle is specified by four coordinates (x1 , y1 ), (x2 , y2 ), (x3 , y3 ) and (x4 , y4 ).

Abstract: PURPOSE:To obtain a conductive core which is free from bending or deformation by forming high density portions in a belt-like metal fiber sintered substrate in its lengthy direction at regular intervals, and welding a nickel corrugated plate thereto so that the thickness of the welded part is thinner than that of the sintered substrate. CONSTITUTION:A high density portion 2 is continuously formed in a part of a belt-like nickel fiber sinter 1 in its lengthy direction, and the bottom of a 0.5mm thick nickel corrugated plate 3 is welded by electric welding to the sinter 1 to form a current collecting terminal. By making the thickness of the welded part of the corrugated plate thinner than that of the porous part of the sinter, biting of the welded terminal into active material filling equipment in an active material filling process is prevented. A slurry-like active material is filled in the porous substrate, and dried to prepare an about 1.5mm thick plate. This plate is pressed with a roller press 4 to make a 0.7mm thick plate. The conductive core which is free from bending or deformation is obtained.

IPC: A61B5/055
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a marker which facilitates production and can become a high-accuracy position target, and production therefor. SOLUTION: The marker for MRI is formed by sealing MRI sensitive gell 1, which is formed by absorbing a nickel chloride aqueous solution in a water- holding material, in a sealed container 4 formed from the acrylic resin of a material almost not to be detected by MRI. Since the MRI sensitive gell 1 is in a gell state, the work of sealing into the sealed container 4 is facilitated and further, since air bubbles or the like are not mixed in comparison with a solution, the marker for MRI is functioned as the high-accuracy position target.
