Title: Heart stimulating device
Inventor: OBEL MARTIN
IPC: A61N1/362
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To surely adjust a pulse by means of a simple lead line by operating a pulse generating means by means of a second mode when a noise IEGM signal with a prescribed signal characteristic is detected in a first noise detecting means and keeping the mode in the second one during a stimulating pulse which comes after noise detection. SOLUTION: The IEGM signals from sensing input sides 1 and 2 are amplified by a sensor amplifier 3 and inputted to detecting means 4-6. The noise detecting means 6 detects the noise IEGM signal having the prescribed signal characteristic. A logical means 7 changes-over a pulse generator 8 into the second mode based on the detection of the noise IEGM signal. Thus, the pulse with high energy is transmitted to the heart of a patient. The second mode is kept during the stimulating pulse after noise detection. An induced reaction detecter 5 is made to be non-operating in the second 1 operation mode and a back-up pulse generator 9 is stopped. Therefore, the continuous adjustment of stimulating energy is automatically made to be non-operating only by the existence of obstacle noise so that safety and a long life are obtained.

Title: Microcomputer
Inventor: OKANO YOSHIAKI
IPC: G06F1/32
Filed: 1985-02-18
Abstract: PURPOSE:To execute a stand-by control by a comparatively simple circuit, by impressing a stand-by start requesting signal to a set terminal of a latching circuit and setting it temporarily to a stand-by state, and releasing it after a prescribed time. CONSTITUTION:When shifting to a stand-by state, a stand-by start requesting signal S2 is impressed to a set terminal of an FF 51. As a result, the FF 51 is set, its Q output becomes a low level, and an output part of an inverter 53, namely, a voltage VN1 of a node N1 is shifted to a lo level. In this shifting process, a threshold value Vth1 of an inverter 55 is higher than a threshold value Vth2 of an inverter 54, therefore, an output of the inverter 55 becomes a high level and a stand-by starting signal S55 is impressed to a stand-by signal generating circuit 56. The circuit 56 outputs a stand-by signal S5 and sets an MPU 2, a memory 3 and an input/output part 4 to a stand-by state. Thereafter, when the voltage VN1 drops and reaches the threshold value Vth2, the FF 51 is reset. When said voltage reaches the minimum value, and thereafter, reaches the threshold value Vth1, the stand-by state is released and shifted to an operation state.

Title: Manufacture of semiconductor device
Inventor: TOKUDA JUN
IPC: G01D5/16
Filed: 1994-02-28
Abstract: PURPOSE:To easily eliminate a retaining structure in a short time, by using an N-type semiconductor substrate, diffusing phi type impurities in the surface part of the semiconductor substrate except at least a retaining structure forming position, irradiating a specified light in specified reaction gas, and eliminating the retaining structure by etching. CONSTITUTION:A cantilever 2 and a peripheral frame part are connected by a retaining structure 3. On the surface of a silicon substrate 1, the conductivity type of only the retaining structure 3 part is N-type, and that of the other part is P-type. Since a P-type layer 5 is formed on the surface of the part except the retaining structure 3, electrons are not formed in the case of light irradiation and the reaction with NF3 gas as the reaction gas is not induced. On the contrary, electrons are formed in the N-type retaining structure 3 in the case of light irradiation, so that etching reaction is induced as the result of reaction with NF3 gas. Hence only the N-type retaining structure 3 part is etched and eliminated by light irradiation.
