Title: Dicing method for semiconductor wafer
Inventor: YAMADA YUTAKA
IPC: B28D5/02
Filed: 1991-09-17
Abstract: PURPOSE:To reduce the number of cracks in a semiconductor wafer during a dicing step by using a resin blade for cutting a groove at a low feed rate after a dicing step with a diamond blade is carried out for a wafer. CONSTITUTION:A semiconductor wafer 1 is half cut to such an extent that the wafer doesn't split off, and thereby a half cutting groove 2 is made. A resin cutting blade has a soft contact with working faces and a blade width less than a diamond blade. With the resin cutting blade, the center of the cutting groove is fully cut at a low feeding rate so that the wafer is cut off completely and an adhesive tape is halfway cut. In this way, a crack caused by a shaking movement of the diamond blade can be prevented. Also the cracks can be reduced in number to a minimum extent.

Abstract: PURPOSE:To prevent the runaway and malfunction of a processor caused by switching a clock frequency during a session by holding the operation of the processor in a standstill state according to a stop signal from a reader/writer and restarting the operation of the processor by the supply of a clock signal in the standstill state. CONSTITUTION:When the clock signal of the prescribed frequency is supplied from a reader/writer 100 to a processor 210 of an IC card 200, the processor 210 is operated at processing speed based on the clock signal. At such a time, when the stop signal is outputted from the reader/writer, a stopping means 220 holds the operation of the processor 210 in the standstill state. When the clock signals of various frequencies, for example, are switched and supplied from the reader/writer 100 in the state that the operation of the processor 210 is stopped, a restarting means 230 restarts the operation of the processor 210. Thus, when the clock signal is switched during the session with the reader/ writer 100, the runaway and malfunction of the processor 210 are not generated.

Filed: 1987-09-19
Abstract: PURPOSE:To execute the measurement with high sensitivity by a simple constitution by providing two pairs of ultrasonic transmitters and receivers on the wall surface of the downstream of a vortex generating body so that acoustic wave propagation paths become parallel and in the opposite directions, and comparing the phases of both output ultrasonic signals. CONSTITUTION:On the inside of a duct line 6, ultrasonic transmitters 9a, 10a and the respective receivers 9b, 10b are provided so that the advance directions of the respective ultrasonic waves a', b' are reversed and one Karman vortex traverses simultaneously the acoustic waves a', b'. As a result, when the vortex passes through, the phase of the acoustic wave a', for instance, leads, and the phase of the acoustic wave b' lags. When the latter half part of the vortex passes through a propagation path of the acoustic wave, the phase of the acoustic wave a' lags, and the phase of the acoustic wave b' leads. Accordingly, by detecting a variation of a phase difference of receiving output signals (a), (b) of this ultrasonic wave by a phase comparator 11, the generation of a vortex can be detected, and by counting the vortex per unit time, a flow velocity and a flow rate of a fluid can be measured. Also, an external factor such as a temperature variation, etc., exerts the same influence on the method for propagating the acoustic waves a', b', therefore, the phase difference of the output signals (a), (b) is not varied substantially.

Title: Strip line, transmission line, resonator and filter using same
Inventor: WAKINO KIKUO
IPC: H01P1/203
Filed: 1993-09-22
Abstract: PURPOSE:To increase Q by forming slits in the length direction of a strip conductor. CONSTITUTION:A strip line 10 includes a dielectric substrate 12. An earth electrode 14 consisting of a metal is formed on the whole surface of one main face of the substrate 12 and a U-shaped strip conductor 16 consisting of a metal is formed on the other main face of the substrate 12. Since two approximately parallel slits 18 are formed, the strip conductor 16 has structure connecting three narrow conductor parts 16a to 16c in parallel. When the length of a part on which current is unevenly distributed is defined as delta, the total length of the conductor parts 16a to 16c becomes 6delta because an eddy current is interrupted by the slits 18. Since current is unevenly distributed only on both end parts of a strip conductor in a conventional strip line, the total length of the current is unevenly distributed parts is 2delta. Thereby a practical cross sectional area is sharply increased as compared with a conventional strip line, so that a loss is reduced and Q can be increased.

Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To obtain a rolling roll with which an rolled stock excellent in surface gloss is manufactured by providing grinding nicks which are inclined at random at the greatest number of angles of less than a specified angle in a stitch shape respectively on both sides of the circumferential direction on the peripheral surface of a roll. SOLUTION: The roll surface is made into the stitch shape by mutually crossing the grinding sticks which are inclined at random at the greatest number of the angles of 0.5 to <90 deg. respectively on both sides of the circumferential direction (same as the rolling direction) of the roll. It is necessary to form the grinding nicks of the roll at a prescribed greatest number of the angles to the circumferential direction, but the angles of the respective grinding nicks are random and it is not necessary to make the greatest number of the angles θ1, θ2 to the circumferential direction of the roll equal (symmetrically). When the greatest number of the angles are 0.5 to <90 deg., preferably, 5-85 deg. from the ease of impartation of the grinding nicks, the improvement of gloss is obtained.  The roll on the outer layer of which a sintered hard alloy is adopted has excellent wear resistance and the surface gloss of the rolled stock is stably maintained for a long term.
