Title: Method and device for conducting division in data processor
Inventor: POORU SHII ROSUBATSUKU
IPC: G06F7/537
Filed: 1993-05-28
Abstract: PURPOSE: To realize an integer/floating point division operation through the use of a single correction SRT divider in a data processor. CONSTITUTION: Floating point/integer division is executed on a normalized plus mantissa (a dividend and a divisor) by using SRT division. Integer division shares a part of a floating point circuit and the sequence of the operation is changed during an integer division operation. The SRT divider 30 executes a series of operations before and behind a repetitive loop and reconstructs the integer/divisor and the dividend for the expression of a data route that an SRT algorithm requests to the mantissa of a floating point. During a repetitive loop, a quotient bit is selected and it is used for generating an intermediate partial remainder. The quotient bit is inputted to a quotient register for accumulating a final quotient mantissa. A mantissa full adder is used for generating the final remainder.

Title: Cold energy preventive method for underground low temperature tank
Inventor: WATANABE MASAYOSHI
IPC: F17C13/10
Filed: 1978-12-07
Abstract: PURPOSE:To keep an underground low temperature tank heated uniformly, by distributing the heating capacity dense at the center of the tank bottom and coarse at the external circumference of the bottom and on the side wall. CONSTITUTION:Pipes 2 with built-in heating wires are so laid that they are parallel in an inner tank 11, pass through an insulating layer 12 being deviated from the parallel extension and rise outside the external wall 13 at equal distances toward above the ground. Since the heating wires are uniformly distributed for the tank, the periphery of tank is heated uniformly. Other advantages of this system include elimination of effect of cold energy from the temperature tank on the structure, reduction in the number of vertical pipes and also reduction of cost with minimum heating facility.

Title: Ink jet printer
Inventor: MIYAZAWA YOSHIO
IPC: B41J2/18
Filed: 1991-06-24
Abstract: PURPOSE:To discharge a bubble in a head while preventing the deterioration of a printing quality and the overconsumption of ink by a method wherein just after air in a cap is temporarily released through an air open valve at the time of cleaning, the air open valve is again closed, and ink is sucked. CONSTITUTION:Cleaning is conducted by discharging foreign particles and bubbles through a cap 9 together with ink using a negative pressure generated by an ink suction pump 11. At this time, bubbles adhering inside the head 1 are hard to discharge even by the sucking force of the ink suction pump 11. Therefore, an air open valve 10 is opened during the sucking action, whereby air in the cap 9 is released. In this manner, the adhering bubbles are sucked reversely to suspend in the ink. After that, the air open valve 10 is again closed, and the ink is sucked. All the bubbles are discharged into an ink discharge tank 13 through an ink discharge tube 12. Then, air in the cap 9 is released by opening the air open valve 10, and a cleaning action is completed.

Title: Surface state inspection device and exposure device using the inspection device
Inventor: KONO MICHIO
IPC: G03F1/84
Filed: 1994-06-08
Abstract: PURPOSE:To detect the existence and non-existence of a foreign material on inspection surface by detecting a beam for optical scan with a detection means, and modulating the optical intensity of a beam from a light source in synchronization with the optical beam scan at the time of inspecting surface state, using a signal from the detection means. CONSTITUTION:In a beam scan system (scan system) for scanning the surface of a substrate such as a reticule or the like with a beam (laser beam), a beat signal is obtained from sideward scattered light from a foreign substance, using heterodyne interference. In this case, the light intensity of a beam from a light source means is modulated, synchronized with a scanning process, for detecting the existence or non-existence of the prescribed size of a foreign substance with high accuracy. Thereafter, frequency shifters 41 to 43 modulate the light intensity of an incident beam during the scan thereof, and thereby act to correct the positional unevenness of detection sensitivity. This modulation is implemented through the adjustment of voltage applied from drivers 40 to 42, to the frequency shifter 41 or 43.

Title: Leaf spring
Inventor: SUZUKI KENICHI
IPC: F16F1/18
Filed: 1979-11-24
Abstract: PURPOSE:To moderate a tensile stress which is to be applied on one face of a leaf, by determining an area around the periphery of a center bolt hole through the tensile stress applied leaf face in a specific form. CONSTITUTION:An area in the vicinity of an upper peripheral edge of a center bolt hole 2 formed through a leaf face 1' to which a tensile stress is applied when a bending moment is created is concaved in the form of an elliptic depression 6 extending in the transverse direction of the leaf spring. The bottom face 6' of the depression 6 is parallel with the leaf face 1' and connected with the face 1' by a smoothly curved line. Thereby, a graphic center of an elastic deformation caused by a bending moment is shifted from a center 7 in a cross section view given before the depression 6 is formed, to a center 8 which can be seen below the center 7 in the drawing. In addition, the second moment of area is varied so that a tensile stress created on the surface of the depression bottom 6' which is about the upper periphery of the center bolt hole 2 may be moderated on account of the property of the cross-sectional view.

Title: Carrier
Inventor: FUJIOKA SEIKO
IPC: B65H5/02
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To hold a pinching carrier force to materials to be carried and suppress abrasion of belts by setting a friction coefficient of one rear rubber layer lower than that of the other rear rubber layer in a drive belt and a driven belt. SOLUTION: When a telephone card (a) is pinched and carried in a contact part between a drive belt 3 and a driven belt 6 in a card type public telephone, the friction coefficient μ2 of the rear rubber layer of the driven belt 6 is set lower than the friction coefficient μ1 of the rear rubber layer of the drive belt 3. Therefore, the friction coefficient between the both belts 3, 6 can be set low compared with the conventional case where the friction coefficient μ2 is set high similar to the driven belt side (for example, μ1=μ2) so that the belt abrasion between both belts 3, 6 can be suppressed thereby. As a result, the pinching carrier force in relation to the telephone card (a) can be sufficiently exhibited.

Abstract: PURPOSE:To enable the bottom quality discrimination of the sea bottom, by a method wherein an amplifier is saturated with respect to the rise part of a received pulse due to reflected ultrasonic waves from the sea bottom and the gain of the amplifier is sharply reduced directly after saturation. CONSTITUTION:A counter 8 is set to a predetermined initial value by a pulse corresponding to the ultrasonic transmission trigger from a transmission triger generating circuit 1 due to a pulse generating circuit 9 and the gain of an amplifier 3 is still held to a predetermined value through a D/A converter 4. In this state, the amplifier 3 is saturated by reflected received ultrasonic waves higher in a level as compared to that to a school of fish or the like and the sea bottom is detected while the saturation output from the amplifier 3 corresponding to the rising of the received waves opens an AND gate 7 through a slice circuit 5. By this method, the pulse from a pulse generating circuit 6 is subtracted by the counter 8 while the gain of the amplifier 3 is reduced and the bottom quality of the sea bottom is discriminated by the non-saturation output from the amplifier 3.
