Title: On-vehicle heart beat detector
IPC: G16H10/60
Filed: 1992-03-19
Abstract: PURPOSE:To remove noises exclusive of heart beat information and to improve the detection accuracy of the heart beats by providing a bioinformation detecting means to be embedded into a seat and vibration sensing means installed in the position different from the position of this means and determining the difference of the output signal of the both means. CONSTITUTION:A piezoelectric element 2 of the bioinformation detecting means 1 converts the various pressure changes, such as rider's heart beats applied to the embedded part, to electric signals. A filter circuit 3 filters the signals of the frequency bands corresponding to the heart beats. An amplifier circuit 4 amplifies the electric signals past the filter circuit 3 and a smoothing circuit 5 rectifies and integrates the amplified signals. A piezoelectric element 7 of the vibration sensing device 6 converts the vibrations, exclusive of the bioinformation of the rider, to electric signals. The filter circuit 8, the amplifier circuit 9 and the smoothing circuit 10 act similarly as the bioinformation detecting means 1. A subtracting means 11 subtracts the signals outputted by the vibration sensing means 6 from the signals outputted by the bioinformation detect means 1. A heart beat detecting means 12 detects the heart beat information included in the signals outputted by the subtracting means 11.

Title: Semiconductor device
Inventor: URAKAWA KAZUYA
IPC: H01L29/74
Filed: 1990-03-13
Abstract: PURPOSE:To prevent short-circuiting between a gate electrode and a cathode by a method wherein an insulating means which is provided with a belleville spring bringing the gate electrode into contact with and connecting it to a chip via a gate support rod composed of an insulator and which prevents the gate electrode from being short- circuited on the side of an anode is formed between a gate support sheet and the belleville spring. CONSTITUTION:A mica washer 16 is used as an electrical insulation means which is formed on the side of a cathode 6, i.e., between a gate support rod 11 and a flat washer 14. It is installed in such a way that a gate electrode 10 does not come into contact with the flat washer 14 even when a sleeve 12 is damaged. Thereby, the gate support rod 11 repeatedly comes into pressure contact and the gate electrode 10 is brought into pressure-contact with and connected to a chip 4 by the pressure-contact face of a belleville spring 15. Even when, e.g. the sleeve 12 is damaged, the gate electrode 10 does not come into contact with the flat washer 14, and the gate electrode 10 and a cathode 6 are not set to a short-circuited state. The electrical insulation means is not limited to this structure. An insulating ceramic sheet 17 may be installed between the gate support rod 11 and the belleville spring 15 so as to prevent short- circuiting between the gate electrode 10 and the cathode 6 when the sleeve 12 is damaged.

Abstract: PURPOSE: To form with ease an uneven pattern rich in a three-dimensional effect on a sheet surface, by radiating ultraviolet rays onto a substrate sheet of ultraviolet ray curing synthetic resin with the masked parts where an uneven pattern is provided, laminating a colored layer onto the surface thereof, and stretching it under heating.  
     CONSTITUTION: Use is made of an ultraviolet curing synthetic resin sheet that has been prepared by blending 100pts.wt. of a base material such as vinyl chloride resin, about 5W60pts.wt. of a photoreactive plasticizer, about 0W120pts.wt. of a conventional plasticizer, a photosensitizer, etc. On this substrate sheet is printed a desired pattern 2 with an ink that does not transmit ultraviolet rays, and then the ultraviolet rays 3 are radiated to cure the sheet 1 except the pattern 2. On the surface of the sheet 1 is then applied a color layer 4 (by printing or by attaching colored synthetic resin sheet) followed by stretching it in the direction shown by arrows P under the influence of heat to recess the pattern 2 of the sheet 1 to form an uneven pattern 2'.

Filed: 1987-03-20
Abstract: PURPOSE:To detect the shifting of the phase of a clock signal in respective distributing destinations by supplying a referring signal to adjust the phase of a clock signal to respective distributing destinations of the clock signal with a second signal channel. CONSTITUTION:In respective phase adjusting means A-C, a phase detecting circuit 102 detects the phase difference between a referring signal sent from a circuit 103 or 103' for driving through a second signal channel 106 and a clock signal through a variable delaying circuit 101 of respective phase adjusting means and feeds back the result to the variable delaying circuit 101. The phase difference detecting circuit 102 controls the signal propagating time of the variable delaying circuit 101 so that an absolute value can be equal and a code can be reversed for the phase difference between the clock signal and the reference signal when the reference signal is sent from left to right on a signal channel 106 of bidirectionality and for the phase difference between them when the reference signal is sent from right to left. Thus, the phase adjustment of the clock signal can be automatized.

Filed: 1983-04-12
Abstract: PURPOSE:To prevent breakdown due to abnormal voltages, without disadvantage to the electric characteristics of an MIS semiconductor device, by providing a resistor means between a substrate and a power source terminal for imparting a potential to the substrate. CONSTITUTION:A reverse conductive type drain diffused layer 3 and a source diffused layer 7, which are formed by diffusion, are provided in a substrate 8. An output terminal 1 is connected to the drain diffused layer 3. A power source terminal 9 is connected to the substrate 8 by way of a resistor means 10 and also connected to the source diffused layer 7. When an abnormal voltage is applied in the reverse direction, a current begins to flow when the junction withstand voltage between the drain diffused layer 3 and the substrate 8 is reached. When a large current is going to flow, voltage drop occurs by the resistor means 10, and the voltage applied to the junction is decreased. Thus the current, which damages the junction, does not flow. When the abnormal voltage in the forward direction is applied, the current is limited by the voltage drop by the resistor means 10, and the damage is hard to occur furthermore.
