Title: High frequency switch
Inventor: HAYASHI HIROAKI
IPC: H01L27/095
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a high frequency switch with a small loss. SOLUTION: Relating to a coplanar high frequency switch formed on a semiconductor substrate, a capacitor 400 is formed between a signal line 100 and a FET 300 to connect the signal line 100 to ground 200 via the capacitor 400 and the FET 300. When the FET 300 is turned off, the capacitance of the capacitor 400 and the junction capacitance of the FET 300 are connected in series. The capacitance resulting from the series connection of the junction capacitance of the FET 300 and the capacitance of the capacitor 400 is smaller than the junction capacitance of the FET 300 itself. Thus, leakage to the ground when a high frequency signal passes the high frequency switch can be reduced. That is, the high frequency switch with a small loss can be realized.

Title: Controlling method for galvanizing bath
Inventor: ISHIHARA HARUHIKO
IPC: C23C2/00
Filed: 1987-12-03
Abstract: PURPOSE:To maintain good plating workability for a long period and to improve quality of a plated product and productivity by removing foreign matters in the galvanizing bath contained in a main pot by filtration and floatation separating operation and clarifying the bath. CONSTITUTION:The height of the galvanizing bath 2 level in a subpot 5 is regulated to same level as a main pot by a communication part 4 and when the bath 2 of the downstream side of a partition wall 6 is returned to the main pot 1 with a circulation pump 11, the bath 2 level of the downstream side part is lowered and difference is caused between this bath level and a bath 2 level of the upstream side of the partition wall 6. Therefore the bath 2 of the upstream side is transferred quietly and smoothly to the downstream side through an inflow port 9 and the foreign matters in the bath 2 are filtered with a ceramic filter 8 without uneven clogging. The foreign matters passed through the filter 8 are allowed to float on the bath 2 level by bubbling due to a bubble blowing device 7 and are removed and discharged to the outside of the system. Therefore, when returning the bath 2 free from the foreign matters by filtration and floatation separating operation to the main pot 1 with the pump 11, the bath 2 in the main pot 1 is always kept in a clean state and thereby quality of a plated product and productivity can be improved.

The linear laser light is obliquely cast into the reflecting surfaces 21a and 22a and made to go back and forth between the surfaces so that the light is cast on floating particulates in the space. Then, a scattering light detector 24 receives the scattering laser light scattered from the floating particulates and converts the light into the electric signal. The signal is outputted. Thus, the position alignment of the mirror 21 and the mirror 22 is ensured, and the number and the diameters of the floating particulates can be accurately measured.

Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To remove heat generated by sliding surface friction by forming a cavity in the bottom of a saddle sliding surface formed on a saddle of a machine tool and by passing coolant in the cavity. SOLUTION: Temperature sensors 22 embedded in a bed sliding surface and a saddle sliding surface 24 detect the temperature of the sliding surfaces. Based on the detected temperature information, a liquid temperature adjustment device sends appropriate temperature and flow rate of water or coolant to a coolant entrance of the bed sliding surface and a coolant entrance of the saddle sliding surface 24 via a line. If friction heat is generated in the sliding surface between the bed and the saddle 10, the water or the coolant is passed in a cavity 18 so as to reduce the heat generated by the sliding surface friction. If the friction heat is generated in the sliding surface between the saddle 10 and a table, the water or the coolant is passed in a cavity 26 formed in the bottom of the saddle sliding surface 24 so that the water or the coolant absorbs the heat.
