Title: Diamond impregnated grinding wheel for processing of ceramic
Inventor: OGAWA KUNIO
IPC: B24D5/00
Filed: 1989-07-19
Abstract: PURPOSE:To enhance the processing speed greatly by giving vibration to the processing surface through contacting of a grinding wheel with a work to be ground, and generating micro-cracks in the work. CONSTITUTION:When a grinding wheel 1 with its shank 3 fixed to the spindle of a grinder is rotated and contacted with a work to be ground 5, the grinding is commenced. At this time, a friction force F will act in the circumferential direction of the wheel 1 owing to the contact pressure of the wheel 1 with the work 5, which should cause a minute deformation at the periphery 1-1. When there is no more contact with the work 5 due to rotation of the wheel 1, deformation to the opposite side is generated. Repetitions of such deformation generate vibration of projections 3 at the periphery 1-1, and the vibration is conducted to other projections 3 off contacting the work 5 owing to so called the principle of tuning fork to put them in vibration also. This vibration causes initiation of minute cracks in the work 5, which is thus ground.

Title: Manufacture of semiconductor device
Inventor: PETER MATIAS
IPC: H01L21/76
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To lessen both leakage current generated in response to the formation of a trench and the generation of high electric field by performing a single process. SOLUTION: After a trench 7 has been formed by dry etching, a wet etching treatment is performed using a mixed solution of H2O2 and HF as an etchant. As a result, the surface layer part of the trench 7, containing crystal defects introduced through the dry etching, is removed. Also since the oxide layer, composed of a silicon oxide, is etched more strongly than the semiconductor substrate 1 which is composed of silicon, the upper edge of the trench 7 on the semiconductor substrate 1 is given roundness. A leakage current is suppressed low by the removal of crystal defects. Since the upper edge 11 is rounded, the concentration of electric field in this part in relaxed, and the generation of high voltage can be suppressed. The effect of the suppression can be accomplished by a singe wet etching process.

IPC: G06F1/32
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a terminal device which can save the power consumption when an abnormal pseudo-input condition occurs without providing special hardware. SOLUTION: When a special key input operation is performed (S106) and, moreover, the continuation time of this special key input condition is judged to be not smaller than a specified value (S108), a low power consumption mode is set (S114). Next, it is judged whether or not there is a special key input operation (S116) and, when the special key input operation is not performed, a step is returned to the step at which existence/nonexistence of the special key input operation is judged and a standby condition is entered until the special key input operation is performed (S116). That is, even if a key is coincidentally pressed during this time, the input is ignored and the low power consumption mode is maintained.  On the other hand, when the special key input operation is performed (S116) and, furthermore, the continuation time of the special key input condition is judged to be not smaller than the specified value (S118), the low power consumption mode is released and a normal power consumption mode is set (S100).
