Title: Multiple mode crystal resonator
Inventor: INAO KIYOHISA
IPC: H03H9/56
Filed: 1992-07-31
Abstract: PURPOSE:To keep an excellent frequency temperature characteristic by forming a lead electrode and an electrode land with different metals and overlapping them and adopting an Al for either of the lead electrode or the electrode land. CONSTITUTION:Electrode lands 20, 21 made of a metal different from that for lead electrodes 6, 7 are overlapped onto the electrodes 6,7 extended from input output electrodes 3, 4 of a crystal chip 1. The lead electrodes 6, 7 are led out from one corner of a diagonal line of the crystal chip 1 and the electrode lands 20, 21 are formed from the diagonal line part to the end in the broadwise direction. Even when an adhesives is shrinked, a slip takes place on a boundary face between the electrodes 6, 7 and the lands 20, 21 to relax a tension caused on the surface of the crystal chip 1. That is, since an Al is adopted for the lands 20, 21, an oxide film is produced with the electrodes 6, 7 and the oxide film weakens the bonding between the both to assist the slip. Then occurrence of distortion due to a tension at a simulated part is avoided and the effect onto a thickness-shear vibration is weak and the substantial frequency temperature characteristic is obtained.

Title: Air conditioner containing pwm inverter
Inventor: YAMANE SHIGEKI
IPC: F24F11/02
Filed: 1984-10-26
Abstract: PURPOSE:To prevent audible vibration and noise from a motor as well as to offer an air conditioner of low cost and, furthermore, the maintenance of a belt becoming unnecessary. CONSTITUTION:When a carrier frequency of a PWM inverter 16 is heightened, the noise value of the air conditioner is largely decreased from about 8kHz, and at about 20kHz the noise becomes the same with the operation noise when the motor 6 is drived by an AC electric source. When the carrier frequency is heightened the input electric power value becomes large and the loss increases. Accordingly, when the PWM inverter 16 of which carrier frequency is above 8kHz and below 30kHz is used, even if a fan and motor is drived directly connected, uncomfortable noise is not generated, and low cost because of pulley is not necessary and maintenance free of a belt can be realized.
