Filed: 1992-09-09
Abstract: PURPOSE:To prevent the contamination of images and characters by the remaining ink, to improve the printing appearance at the time of multi-color printing and to realize both the water-proofness and light resistances, by adding a cationic resin obtained through the reaction of the secondary amine with epihalohydrin at least to the surface of a recording paper. CONSTITUTION:The inkjet recording paper is constituted by adding a cationic resin obtained through the reaction of the secondary amine with epihalohydrin at least to the surface thereof. At this time, the secondary amine is selected from, for example, dimetylamine, piperidine, carbazole, etc. Moreover, the epihalohydrin is selected, e.g. from epichlorohydrin, epibromohydrin, epiiodohydrin and the like. Accordingly, it is prevented that the images and characters are contaminated by the remaining ink. Moreover, images and characters with good appearance can be obtained at the time of multi-color printing. At the same time, both the water-proofness and light resistances are satisfied in this inkjet recording paper.

Title: Semiconductor integrated circuit apparatus
Inventor: MURANAKA MASAYA
IPC: G06F21/75
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent an operation mode from starting wrong and from being set by a third party by making a count operation of a first counter circuit correspond to an input operation for input signals, practically stopping the operation of the first counter circuit when the operations do not coincide and permitting the operation mode by a maximum value output of the counted value. SOLUTION: A comparing circuit CP compares complementary count signals of non-inversions Q0-Q3 and inversions Q0B-Q3B from a counter circuit CNT with address signals LA0-LA3 and inverting signals LA0B-LA3B from an input circuit INC, and outputs comparison outputs C0-C3. A judging circuit LC1 turns an output signal COIN to a low level when one of the comparison outputs C0-C3 is in an incoincidence state and clears the counter circuit CNT. A logic circuit LC5 counts count outputs of the counter circuit CND, that is, high levels of the non-inversions Q0-Q3 and forms a start signal OPEN when a counted value becomes 1111 in binary notation.

Title: Oil feeding device
Inventor: KANEKO MASAKI
IPC: B67D7/78
Filed: 1994-10-05
Abstract: PURPOSE: To ensure the prevention of the accumulation of air in a spare pump, even if the operation of the spare pump is stopped over an extended period of time. CONSTITUTION: The suction openings of two oil pumps 2A and 2B communicate with each other by a connecting pipe 11. A pump 2A in operation draws lubricating oil up from an oil tank 1 through a suction pipe 3A, a suction pipe 3B and the connecting pipe 11. The air entering the spare pump 2B on standby and its suction pipe 3B, together with the lubricating, is sucked by the pump 2A in operation through the connecting pipe 11. Therefore, the spare pump 2B on standby and its suction pipe 3B will not be filled with air.

Title: Device for correcting warpage of printed wiring board
Inventor: ARAI TAKAFUMI
IPC: B29C53/18
Filed: 1988-09-27
Abstract: PURPOSE:To efficiently rectify it according to the degree of warpage by arranging a heat insulating sheet whose thickness is varied over the whole length freely in sliding between cooling plates of a cooler, and bringing the specific thickness part of the heat insulating sheet into close contact with the inside of one cooling plate so as to cover it. CONSTITUTION:The temperature at the surface side 1a where a warp is occurring in a printed wiring board 1 in a cooling process is lowered than that at the rear side 1b. Hereby, the surface side 1a is cooled quickly, and tensile stress turns out to work, and the warpage is corrected, but by bringing a heat insulating sheet 3 into close contact with the inside of a cooling plate 2 where the rear side 1b of the printed wiring board 1 is located so as to cover it, temperature difference can be set between both cooling plates 2 even if the temperature of the cooling plate itself is not adjusted. The surface side 1a of the printed wiring board 1 turns out to be cooled quickly by other cooling plate 2, and a warp is rectified. Moreover, since the thickness of the heat insulating sheet 3 varies over the whole length, by bringing the specific thickness part into close contact with the inside of the cooling plate so as to cover it, temperature difference can be set specifically between cooling plates 2, thus it can be made to cope with the degree of the warpage.

Filed: 1987-09-24
Abstract: PURPOSE:To lighten the pitch condition of an exclusive OR circuit by disposing an inspecting bit for every sort and inspecting the parity of an information bit for every sort to which the information bit belongs. CONSTITUTION:When a number displayed by a kth adic number is sorted for every number in which a lth digit is m and the number displayed by the kth adic number is arranged to delimit at every (k) from an end, the information bit is matched to the respective elements of a series arranged so as not to have more than two numbers belonging to the same sort in one interval. The inspecting bit is disposed for every sort and the parity of the information bit is inspected for every sort to which the information bit belongs. Accordingly, at the time of delimiting the information bit for respective k bits from the end, since more than two information bits belonging to the same sort are not included in the respective intervals, one exclusive OR circuit may be disposed to the respective intervals of the k bits. Thereby, the pitch condition of the exclusive OR circuit is lightened.

IPC: H01L23/495
Filed: 1985-10-28
Abstract: PURPOSE:To obtain terminals having both automatic-mounting corresponding and non-corresponding shapes by cutting down unnecessary terminal portions in response to the requirement of products by mounting auxiliary terminals positioned on both sides of fundamental group terminals to a lead frame for a semiconductor. CONSTITUTION:With a lead frame, a terminal 1, a terminal 2 and a terminal 3 are used as fundamental combination, and each terminal is fixed by a tie bar 4 orthogonal to these terminals and a wide band 6 supporting the terminals. Auxiliary terminals 5 are each arranged at left and right positions separate from the terminals 1 by 2.5mm between the tie bar 4 and the wide band 6. A semiconductor device is assembled, and head sections are sealed with a resin 7. When an automatic-mounting corresponding shape is to be acquired, the tie bar 4, the terminals 2, the terminals 3 and the wide band 6 may be cut as indicated by broken lines in the figure. When an automatic- mounting non-corresponding shape is to be obtained, the tie bar 4, the auxiliary terminals 5 and the supporter 6 for the terminals are cut as indicated by broken lines in the figure. Since a molding process for the terminals is eliminated, dimensional accuracy is improved remarkably, thus eliminating the trouble of the plane alignment requirement of each terminal.

Title: Phase synchronizing receiver
Inventor: YAMANE TOSHINOBU
IPC: H04B1/26
Filed: 1990-09-12
Abstract: PURPOSE:To easily obtain resynchronism by sweeping in a fine range even when the frequency of a received signal is deviated by generating the control voltage of a phase synchronizing loop based on the output frequency of a voltage controlled oscillator just before missing the received signal stored in a memory when the received signal is missed, and sweeping the voltage. CONSTITUTION:When the received signal is interrupted after the phase locked loop is temporarily locked, a microprocessor 9 controls a voltage controlled oscillator 4 through the output of a D/A converter 10 so as to be coincident with the count value of a counter 7 obtained before the received signal is interrupted, and the resynchronism is obtained by a little sweeping around the frequency. Thus, even when the frequency of the received signal is deviated or an oscillation frequency is deviated to the control voltage of the voltage controlled oscillator 4, the resynchronism can be easily obtained by sweeping within a fine range based on the oscillation frequency of the voltage controlled oscillator 4 to be held in a memory 8 just before the received signal is interrupted.
