Title: Method and device for laser cleaning
Inventor: KATO YOSHIHISA
IPC: B23K26/046
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To surely separate and remove attached stuff without degenerating or wearing the surface of a work to be cleaned. SOLUTION: The continuous short-pulse laser beam to be outputted from a laser beam oscillation unit 12 is fed to a laser beam irradiator 16 through an optical transmission tube 32, and the surface of the work to be cleaned is irradiated with the short-pulse laser beam from the irradiator 16. The intermittent thermal shock wave is generated on the surface by the irradiation of the short-pulse laser beam on the surface of the work to be cleaned. The thermal shock wave generates the fine resonance, and the attached stuff is separated and removed from the surface of the work to be cleaned by this resonance effect.

Title: Transmitting circuit for buzzer
Inventor: NAKAGAWA SHUJI
IPC: G10K9/12
Filed: 1987-11-30
Abstract: PURPOSE: To obtain a stable oscillation frequency which is not changed by voltage variance by using a comparator to constitute an oscillation circuit for buzzer. CONSTITUTION: When a voltage Vcc is applied to a comparator 1, the voltage of an non-inverted input terminal 3 goes to K2 Vcc, and an output 2 of the comparator 1 goes to the high level because it is higher than the voltage of an inverted input terminal 4. Next, the voltage of the inverted input terminal 4 rises because a capacitor C1 is charged through resistances R1 , R6 , and R5 by Vcc; and when it exceeds the voltage of the non-inverted input terminal 3, the output 2 is changed from the high level to the low level. At this time, the voltage of the non-inverted input terminal goes to K1 Vcc, and the voltage of the inverted input terminal 4 gradually falls from the voltage K2 Vcc because the capacitor C1 is discharged through the resistance R6 .  Since the voltage of the non-inverted input terminal 4 is repeatedly charged and discharged as shown by 5 and 6, oscillation is executed. Thus, a stable oscillation frequency is obtained without enlarging the outside shape of a buzzer.

SOLUTION: Whether the ABS control or the like is executed or not is judged (S200), and when it is executed, the data on vehicle condition after the break-in of the stability controlled system (SCS) is stored in a RAM (S202). When it is not executed, whether the data is more than a specific value or not is judged (S204), so that the SCS control is broken in and then the data is stored (S202) when the data is more than the specific value because it means that the vehicle travelling condition is suddently changed. Further when the data is over the specific value, the data before the break-in of the SCS control is stored (S206). In case when the SCS control is switched to be operated (S208), a time of the switching, that is, the time when the trouble is generated is set (S210).  When the SCS control is still not operated thereafter, whether a situation is immediately after the completion of the operation or not is judged.

IPC: A61B17/22
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To enable an ultrasonic forceps coagulation device to limit the clamp force bringing good touch-feelable feedback, by partitioning a cage of a spring by one of either an operation lever or a drive york and a slot of the spring by the other and transmitting the force transmitted from the operation lever to the drive york by the spring. SOLUTION: An operation lever 222 is mutually connected with a reciprocatable actuating member 170 by a drive york 220 and a drive collar 200 and rotatably connected with a housing. Movement of the lever 222 toward a grip pat 224 moves the actuating member 170 to the proximal position and rotates a forceps arm 190 in the direction of an end effector 180'. The force loaded on the reciprocatable actuating member 170 of the equipment by rotating motion of an operation lever 22 actuated through the drive york 220 and the drive collar 200 is limited by the force of a spring 226 to press a spring flange 230. Application of excess force brings rotating motion of the spring flange 230 of the operation lever for the drive york 220 against the spring 226.

At this time, by controlling current density, a lower plating layer of high Cr content is formed and then an upper plating layer of low Cr content is formed to a thin thickness by using the same plating bath. It is preferable to form a Zn-type plating layer containing, by weight, 5-30% Cr and 0.001-5% organic high polymer as the above lower plating layer and also to form a Zn-type plating layer which contains 0.01-<5% Cr and <=1% organic high polymer and in which coating weight is regulated to >=0.5g/m<2> as the above upper plating layer. Further, cation polymer is suitably used as the above organic high polymer. By this method, the highly corrosion resistant composite electroplated steel sheet of high Cr content excellent in chemical conversion treating property can be obtained easily and practically.
