Title: Brazing sheet for refrigerant passage for heat exchanger mode of al
Inventor: ISHIKAWA KAZUNORI
IPC: C22C21/00
Filed: 1989-10-05
Abstract: PURPOSE:To suppress the Zn diffusion from a sacrificial material to a core material and to prevent the degradation in pitting corrosion resistance by using an Al-Zn alloy specified in recrystal grain size after brazing to the sacrificial material and using an Al alloy nobler in the potential than the core material for the core material. CONSTITUTION:An Al alloy brazing material is clad on the outer side (atm. side) of the core material consisting of the Al alloy and the sacrificial material of the Al alloy is clad on the inner side (refrigerant side) to form the brazing sheet for the refrigerant passage of the heat exchanger made of the Al. The Al-Zn alloy having >=100mum recrystal grain size after brazing is used for this sacrificial material and the Al alloy, such as Al-Mn alloy, nobler in the potential than the sacrificial material is used for the core material. The Zn diffusion is suppressed even when the material is formed thin. Since the ratio at which the thickness of the Zn diffused layer occupies in the total thickness of the sheet is lowered, the degradation in the long-term pitting corrosion resistance is suppressed.

Filed: 1985-11-22
Abstract: PURPOSE:To measure a displacement of an object to be measured, from a variation of an acoustic pressure which is generated by the displacement of the object to be measured, by utilizing a variation of an acoustic impedance. CONSTITUTION:A diaphragm 11 is vibrated by an input current (i) from an oscillator 3, and a sound of a volume speed being proportional to the current (i) is generated. By the generation of this sound, air passes through a hole 12, and goes in and out through a gap between a sound source 1 and an object to be measured 2, but when an acoustic impedance of this gap is varied, magnitude of an acoustic pressure (p) is also varied. Also, the acoustic pressure (p) at that time is detected by a microphone of an acoustic pressure detector 4. That is when the gap becomes narrow, the acoustic pressure (p) becomes large, and when the gap becomes wide, the acoustic pressure becomes small. An output voltage (e) of the detector 4 is displayed on a meter 8 as a DC output Eo, through an amplifier 5, a filter 6, and a rectifying circuit 7. In this way, a displacement of the object to be measured 2 can be known.

Title: Piezoelectric transformer
Inventor: KAWASAKI OSAMU
IPC: H01L41/107
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To reduce strain and stress during vibration, by providing a primary side electrode at the center of a rectangular plate, suppressing vibration of the λ vibration mode and exciting only the λ/2 vibration mode. SOLUTION: Electrodes 2a and 2b are formed on one main surface of a rectangular plate 5 and at the center of its back surface, and an electrode 3 is formed on the side surface of one short side of the main surface. Lengths of the electrodes 2a and 2b is shorter than that of the rectangular plate 5 so that its edge part does not overlap with the short side of the main surface. The mechanical resonance vibration in the longer direction of the rectangular plate 5 that occurs due to the application of an AC voltage to a pair of primary side electrode 2a and 2b is converted to a high voltage by piezoelectric effect and is taken out of a pair of secondary side electrodes 3 and 2b, thus increasing the amount of induction charge of a pair of primary side electrodes 2a and 2b due to vibration of the λ/2 mode.  However, the charge of the λ mode is canceled out since the sign changes at the center of a piezoelectric transformer 1 that is inside the electrode part, thus reducing the amount of induced charge and hence forcibly exciting only the λ/2 mode.
