Abstract: PURPOSE:To make it possible to effectively prevent cracks from being generated, by providing ribs on high stress generating sections in the outer peripheral surface of a dome-like ceramic cylinder to enhance the thermal-stress resistance thereof. CONSTITUTION:Ribs 2, 2', 3, 3' are projected, on front and rear sides and left and right sides of an elongated hole 1 for a fuel injection nozzle and a glow plug, which is opened in the top section of a dome-like inner cylinder 10, each on each side. Further, ribs 4, 4' are formed in the vertically center section of the inner cylinder 10 in the direction of the minor axis of the elongated hole 1. Each rib is preferably formed in a circular or elliptic doughnut-like shape. With this arrangement, the parts in which a high stress is generated, are concentrated at 6 positions corresponding to the positions of the ribs, and therefore, it is possible to prevent cracks from being generated, and as well, the ribs inforce the binding fore between the inner and outer cylinders, thereby it is possible to prevent them from being vertically shifted from each other.

Title: Long side vibration crystal resonator
Inventor: KAWASHIMA HIROFUMI
IPC: H03H9/19
Filed: 1991-01-16
Abstract: PURPOSE:To realize the long side vibration crystal resonator without leakage of vibration with a low equivalent series resistor R1. CONSTITUTION:The vibrator 1 consists of a vibration section 2, a bent section 3, a bridge section 4, a frame 5 and a support section 6. Moreover, exciting electrodes 9, 10 are formed on upper and lower faces of the vibration section 2 opposite to each other with a different pole, and prolonged to a mount section 7 of one of the support sections 7. Thus, the long side vibration is caused by applying an alternate voltage between the exciting electrodes 9, 10. The vibrator is displaced also in the short side direction by the long side vibration. The displacement is propagated to the bent section 3 via the bridge section 4 and the mode is converted into the bent mode. In this case, the vibration is propagated somewhat up to the frame 5, and since the support section 6 having a hole 8 is connected to the frame 5, the vibration of the frame 5 is not entirely propagated to the mount section 7 of the support section 6 especially and no leakage of vibration is caused even when the mount section 7 is supported and fixed to a seat base or the like.
