Title: Detection of collision by combination of accelerometer and high-frequency pressure transducer
Inventor: MAAKU EI ROSU
IPC: B60R21/01
Filed: 1995-03-10
Abstract: PURPOSE: To make reliable sensing of the half period of the strength of collision, the colliding direction, and initial speed change by the combined use of a low frequency accelerometer and a plurality of high frequency sensors. CONSTITUTION: A high-frequency detection circuit 14 has a series of high-frequency pressure converters 16 for detecting a high-frequency signal, resulting from the deformation of metals during a collision, and each converter 16 severally has BPF 18. Each converter 16 detects the collision in either of the frequency bands different in a certain fixed number, so as to more accurately express the violence of the collision, and sends a detection signal through an A/D converter 20 to a microprocessor 22. The processor 22 judges whether the development of an airbag is necessary or not from this signal and signals sent from a low frequency accelerometer circuit 12 about the directional information of the collision and the deceleration information of a vehicle, and gives necessary signals to an airbag-activating circuit 24.  In this case, a passenger restraining device 10 can be formed near the airbag as a single assembled body in a section for the passenger.

Title: Speaking-type insulation resistance meter
Inventor: ASAKURA EIZOU
IPC: G01R27/14
Filed: 1980-04-17
Abstract: PURPOSE:To increase the workability and at the same time realize hearing of the result of measurement at a remote place, by sending the result of measurement after converting it into the voice. CONSTITUTION:When the probe 3 and clip 4 are connected to the subject of measurement, the resistance detector 2 detects the leak current. This detection signal is converted by the logarithm converter 7 and then by the A/D converter 8 to be applied to the voice synthesizer 10. Here the result of measurement is converted into the voice and is delivered through the speaker 15. Owing to such speaking type, the operator does not need to look at the readings of the meter. Thus the workability is increased. Furthermore the microphone 13 and the transmitter/receiver 19 are provided and switched to each other to transmit the result of measurement to a remote place. At the same time, such a device is also used as a transceiver.

Filed: 1979-04-27
Abstract: PURPOSE: To provide rubber compsn. in which working properties are improved without lowering physical properties, by a method wherein 1,2-polybutadiene is blended with natural rubber contg. vulcanized rubber powder and sulfur.  
     CONSTITUTION: 5W300pts.wt. of vulcanized rubber powder and 4W10pts.wt. of sulfur are blended with 100pts.wt. of a mixt. consisting of 5W80pts.wt. of 1,2- polybutadiene and 95W20pts.wt. of at least one rubber selected from natural rubber and synthetic rubbers. It is preferred to use 1,2-polybutadiene having a vinyl bond content of not less than 70%, crystallinity of not less than 5%, and an intrinsic viscosity [η] of not less than 0.7 (at 30°C in toluene). Such 1,2-polybutadiene can be obtained by using Ziegler type catalyst. When the amount of 1,2-polybutadiene sued in the blend exceeds 80wt%, beneficial result can not be expected and the tensile strength of vulcanized material is lowered. Below 5wt%, improvement in working properties is insufficient.

Title: Semiconductor device
Inventor: IGARASHI YUKIO
IPC: H01L29/74
Filed: 1978-04-28
Abstract: PURPOSE: To prevent the break-through and breakdown of a SCR by increasing a non-trigger gate voltage and a non-trigger gate current by devising the constitution of the gate part.  
     CONSTITUTION: The interval between the connection point of gate electrode 8 and auxiliary gate electrode 9 is widened and wide conductive film 11 is provided between the both. Film 11, using Al as well as cathode electrode 7, auxiliary gate electrode 9 and anode electrode 10, is formed long along N layer 6 coming in ohmic contact with P layer 4. In the above constitution, a gate current flows into film 11 from the connection point of electrode 8 via P layer 4 and then into auxiliary gate electrode 9 from the entire surface of film 11 via P layer 4 and N layer 6. During this, the natural resistance of the substrate causes a voltage drop including a pn junction and, in consequence, non-trigger gate voltage VGD 2  and non-trigger gate current IGD 2  both increase so as to prevent rhe break-through. In addition, the local convergence of the current is avoided and the element breakdown is also prevented.

Title: Production of foamed-in-place polyolefin resin molding
Inventor: YOSHIMURA SHIYOUHEI
IPC: B29C59/00
Filed: 1982-03-30
Abstract: PURPOSE:To produce the title molding which is reusable and has physical properties similar to those of moldings obtd. by using conventional crosslinked pre- expanded particles alone, by mixing crosslinked and uncrosslinked pre-expanded polyolefin resin particles, and expansion-molding the mixture by heating. CONSTITUTION:A mixture of uncrosslinked and crosslinked pre-expanded polyolefin resin particles is charged in a molding die and expanded by heating to produce a foamed-in-place polyolefin resin molding. Since the molding temp. range of this process is greatly widened as compared with the case where molding is conducted by using uncrosslinked pre-expanded particles alone, severe molding conditions are not required so that molding can be easily conducted. The resulting expanded molding has physical properties similar to those of moldings obtd. by using conventional crosslinked pre-expanded particles alone. Further, this process has an advantage in that the resulting expanded molding is reusable, while the expanded molding obtd. by using the crosslinked particles alone is not reusable, because the molding can not be melted.

Filed: 1990-03-02
Abstract: PURPOSE:To reduce burden on a magnetron by sensing the input current of an inverter circuit driving the magnetron and also the pos. electrode current of the magnetron, and thereupon controlling a switching transistor of inverter circuit. CONSTITUTION:Input current of a driver circuit for a magnetron 11 equipped with a switching transistor 7 is sensed by an input current sensing means 12 and an input sensor circuit 18, which the pos. electrode current of the magnetron 11 is sensed by a pos. electrode 4 sensing means 11 and a pos. electrode current sensor circuit 26. These outputs from sensing are fed to a control circuit 8, which prolongs the On period of the transistor 7 if the input amperage is low, or if a temp. rise has caused sinking of the pos. electrode current of magnetron, while shortens the period if high, through On/Off control of the transistor 7, and thus the power supplied to the magnetron is controlled. As a result, overloading is prevented and the burden on the magnetron is reduced, to lead to prolonging of the lifetime of the magnetron, and also in case it is used in a cooking apparatus, a uniform finish condition of cooking is obtained.
