Title: Semiconductor pressure sensor
Inventor: ASANO SHOGO
IPC: G01L9/04
Filed: 1990-09-21
Abstract: PURPOSE:To reduce the influence on a soldering part of a thermal stress and improve its reliability by forming a buckled stress moderating part on a lead terminal after mounting a socket. CONSTITUTION:When the environmental temperature is changed in the mounting part of an engine controller, a hybrid circuit board 35 and a socket 46 are thermally expanded to generate a thermal stress in which the socket 46 relatively presses a lead terminal 42 and the hybrid circuit board 35. Then, the horizontal frame 48 of the socket 46 is relatively pressed to the clip part 43 of the lead terminal 42, and according to this, the lead terminal 42 is pulled to extend a stress moderating part 45, and by this extension of the stress moderating part 45, the thermal stress is moderated. Therefore, the stress by thermal expansion is prevented from collectively acting on a soldering part 62 which is the joint part between the lead terminal 42 and the circuit board 60 of the engine controller, and the reliability of the soldering part 62 is improved.

Title: Method for calculating loss of transmission line
Inventor: SAITO MASAHIRO
IPC: H04B3/46
Filed: 1993-10-08
Abstract: PURPOSE:To obtain a method for calculating a loss by which an accurate level loss is obtained from a few continuous data and its range is expanded by calculating the loss from a characteristic of level loss data measured while varying a signal frequency. CONSTITUTION:A signal output terminal 1 of a signal generator 9 and a measurement terminal 2 of a level meter 11 are connected to a signal terminal 3 of a device to be tested 5, a signal input terminal 4A of a measurement device 7A or a signal input terminal 4B of a measurement device 7B. Then the output level of the signal generator 9 is made constant and the level loss of a transmission line 8 is measured by the level meter 11 while varying the frequency at a predetermined interval for a frequency band required for the test. Then the frequency characteristic of the level loss is calculated to decide an approximated polynomial to which the frequency - level loss characteristic is adapted and the coefficient is calculated by a matrix. Thus, when the signal frequency is known, the level loss is easily calculated based on the polynomial and the coefficient. Furthermore, the loss is predicted even in a range in excess of a measurement limit.

Abstract: PROBLEM TO BE SOLVED: To dispense with enlargement of the size, and make a small turn possible so as to improve excavation workability, by shifting a turning axis to the front side from the center between right and left crawler type running devices and positioning it, and adjusting the ground contact length. SOLUTION: In the beginning of excavation by a back hoe device 11, excavation is executed after ground contact of a bucket 17 far away from the machine body. In this case, floating up force of the machine body due to reaction is prevented by lengthening the rear side ground contact length of crawler type running devices 2R, 2L and shifting the center of gravity of the machine body rearward. Meanwhile, at excavation in the condition of deeply putting the bucket 17 in the earth, dragging of the machine body due to reaction of excavation is prevented by ground contact of a dozer device 10 provided on the front part. Further, when the back hoe device 11 is operated in the reverse direction to the dozer device 10 and excavation is begun, the dozer device 10 is used as an outrigger, and the center of gravity is shifted frontward so as to prevent floating up.  Further, the rear side ground contact length is lengthened so as to prevent the machine body from being dragged, and the workability is prevented from being influenced.

Title: Method for adjusting oxygen cowtent of tantalum material
Inventor: JIEIMUZU EE FUAIFU
IPC: H01G9/052
Filed: 1990-09-26
Abstract: PURPOSE: To control the oxygen content of a tantalum material without contaminating the tantalum material by heating the tantalum material under atmosphere containing hydrogen and existence of tantalum getter-metal having lower oxygen concn. than the tantalum material. CONSTITUTION: The tantalum getter-metal having lower oxygen concn. than that of the tantalum material is set at a position nearest to the tantalum material. The tantalum getter-metal can be mixed with the tantalum material and can be used in the physical-form which can easily separate from the tantalum material. For example, in the tantalum powder, the tantalum getter-metal having different physical form and/or size, is mixed. Then, the mixed material is heated at about 900 - about 2,400 deg.C under atmosphere containing the hydrogen. By this method, the oxygen content in the tantalum material is reduced and held to a constant or the absorbing quantity of the oxygen can be minimized to obtain the material suitable to manufacture a condenser.

IPC: F24H3/04
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To realize a safe and comfortable hot air heater by which the contamination of indoor air is suppressed when the heating operation is extended. SOLUTION: A combustion operation of a burner 9 is started by operating a fuel solenoid valve 8 and a sparker 7 when a turning on button 2 is controlled, and at the same time, when an extending button 3 is controlled, the heating operation of the burner is extended to a period of time which does not exceed a previously set period of time being set by the turning on button control. Also, every time the extending control is performed, the extending operation period of time is set so as to be shortened gradually by a control circuit 5 which controls the fuel solenoid valve 8, for the constitution of a hot air heater.  By this method, when the heating operation is extended, the operation time is gradually shortened, and the degree of a contamination of the indoor air is reduced in response to the shortened operation time, and this method contributes to the improvement of the amenity and safety of the hot air type heater.
