Title: Connection structure of surface acoustic wave device and substrate
Inventor: KAJIWARA TAKAHARU
IPC: H03H9/145
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To improve out-of-band decay quantity by permitting structure to be the connection one where a ground pattern is grounded only at one place in an input side IDT(interdigital terminal) and an output side IDT. SOLUTION: A case 37 is provided with an input terminal 34 connected to the input side IDT 32, an output terminal 35 connected to the output side IDT 33 and ground terminals 36a and 36b respectively connected to the input side and output side IDTs 32 and 33. The ground terminals 36a, 36b and the ground terminal 38 of the case 37 are grounded on a substrate 39 in one place within them. Another ground terminal 38 of another case 37 is in a non- connection state. The front surface and the back surface of the ground pattern on the substrate 39 are cut. Thus, it is eliminated that the earth current of the input side IDT 32 is permitted to flow in the neighborhood of the grounded terminal of the output side IDT 33 so as to make the ground potential of the output side IDT 33 unstable. Therefore, out-of-band characteristic is improved.

IPC: B03C3/00
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To allow a differential electromobility classification system to be operated at the atmospheric pressure or below and to classify fine particles having specified particle sizes into particles having a uniform particle size by a method in which the projecting distance between a carrier gas ejection port and a classification part slit is decreased to improve sheath gas exhaust efficiency in an apparatus, an ultra-fine particle moving distance in classification is decreased to prevent the deterioration of resolution in Brownian diffusion. SOLUTION: Sheath gas 103 is introduced into a differential electromobility classification system, made uniform isotropically by a sheath gas buffer 104, and discharged from a sheath gas exhaust port 113 by way of a filter 118 and a classification part 109. Charged ultra-fine particles 119 are carried by carrier gas 107 from a distance- reduced carrier gas ejection port 110 by way of a slit part 111, exposed to an electrostatic field in the classification part 109, and turned in the axial direction of a cylinder according to the electromobility of the charge number and the particle size. Only the ultra-fine particles 119 which reached the slit part 111 in the lower part of an inner cylinder are taken out as classified ultra-fine particles 120 from a carrier gas exhaust port 115.  In this way, operation is done at the atmospheric pressure or below, and classification is enabled for the ultra-fine particles 119 of 1-20 nm in particle size into particles having a uniform particle size.

Title: Controlling method for drive of hammer for printing
Inventor: SAITO TETSUYA
IPC: B41J9/44
Filed: 1988-04-12
Abstract: PURPOSE:To control the braking of a printing hammer and to improve a printing speed by auxiliarily braking the hammer in response to the speed of the hammer at the time of reciprocation when the hammer is impacted, and then finally braking it in response to the returning speed at the time of returning. CONSTITUTION:When a hammer shaft 9 is driven and a signal detected by a sensor 12 is output from a pulse forming circuit 101 as a pulse, a CPU 102 receives an interrupt input. Then, whether the pulse is PC=1 or not is judged. In case of PC=1, a timer 103 is started to measure a period TAB of times be tween A and B. In case of PC=2, the content of the timer 103 is stored in a register TAB in the CPU 102. Thereafter, a delay time DELTAt and an exciting time l are read from a ROM table in the CPU 102. When the delay time DELTAt is elapsed, the hammer is energized for the time l, and auxiliarily braked. Subsequently, after the hammer is hit, the returning speed of the hammer is set to TCD in the similar procedure to measure it. The delay time DELTAT and the exciting time L corresponding to the TCD are read from the table in the CPU 102, thereby finally braking it as an original braking.

Title: Error correction system
Inventor: ABE TAKAYUKI
IPC: G11B20/18
Filed: 1986-04-18
Abstract: PURPOSE:To improve the error correcting capability by using an error signal for demodulation as a pointer to give the same correcting capability as a conventional product code to a single correction code which is not a product code. CONSTITUTION:In case of demodulation at the data read time, an error detecting circuit 16 detects data which does not accord with modulating and demodulating rules, and the pointer is set in the address where this data occurs. An error correcting circuit 13 reads out data from a sector buffer 12 and refers to the error pointer set in the error detecting circuit 16 to find the address where the error occurs. Thus, the error is corrected with the correcting capability exceeding the essential error correction code capability.

Title: Semiconductor differential amplifier circuit
Inventor: KONDO KENJI
IPC: G11C7/06
Filed: 1989-04-06
Abstract: PURPOSE:To prevent the increase in the drive load capacity from causing a delay in a data transmission time of a differential amplifier by making 1st and 2nd transistors(TRs) inactive when no differential amplifier is selected. CONSTITUTION:When a differential amplifier AK1 is selected and a selection signal Y1 is at an L level, since 1st and 2nd TRs (TRs TF1, TG1) are turned off and an output of an inverter N1 is at an H level, a TR TC1 is turned on and a differential amplifier AK1 is operated similarly as a conventional differential amplifier. However, when the selection signal Y1 goes to an H, the TRs TF1, TG1 are turned on and the TR TC1 is turned off and the TRs TA1, TA2 are inactivated independently of the level of output signals INA1, INB1. Thus, the decrease in the level between two output lines DA, DB via the TRs TF1, TG1 is prevented. Thus, the amplification factor of the differential amplifier is increased without causing a delay in the transmission time.
