Title: Semiconductor pressure sensor
Inventor: ASANO MITSUHIKO
IPC: G01L9/04
Filed: 1986-12-26
Abstract: PURPOSE:To hold airtightness strictly between a sensor element and the top of a base, and a pedestal and a housing body by covering the pedestal with part of the resin of the housing body by melting. CONSTITUTION:A recessed part 18 is formed in the center of the housing body 16, the pedestal 12 is mounted on its bottom, and a rib 30 whose upper end is higher than the top surface of the pedestal 12 is formed around the recessed part 18. Then the rib 30 is molten to deform and flows onto the edge part of the pedestal part 12, thereby covering the pedestal. Consequently, the pedestal 12 and housing body 16 are joined airtightly to form an airtight sealing part at the peripheral part of the pedestal 12, thereby making complete airtightness between a reference pressure chamber 24 and the outside. Consequently, a sensor part is not peeled off the housing part 16 owing to corrosive fluid, etc. This sensor is therefore applicable to fluid of this kind and the housing body 16 is molded of inexpensive resin and reduced in cost.

Title: Fore pile generating method
Inventor: NAKAHARA IWAO
IPC: E21D9/04
Filed: 1994-12-14
Abstract: PURPOSE: To reduce the wear of an inner bit and increase the carryingout effect of slime by longitudinally injecting the drilling water, longitudinally advancing via the collision with the inner wall of a reinforcing steel pipe, generating negative pressure via the jet, and sucking and discharging the slime into the steel pipe from the gap between the inner bit and a drilling bit. CONSTITUTION: When the drilling water W is injected obliquely forward at a high pressure from a jet nozzle 79, the water W is bent by a taper section 87 and injected forward from an edge 71a. The wear of an inner bit 71 is sharply reduced. When the water W is injected obliquely backward from the jet nozzle 79, a negative pressure is generated in the front of the jet nozzle 79, and the slime generated by drilling is sucked into a reinforcing steel pipe 59 from between the inner bit 71 and a drilling bit 79. The carrying-out effect of slime is improved. Drilling can be conducted while the inner bit 71 is stored in the steel pipe 59 or protruded from it. An inner pipe 61 is returned into the steel pipe 59, and the water W is injected to resolve slime plugging. The drilling efficiency can be increased.

Filed: 1987-12-08
Abstract: PURPOSE:To aim at enhancing the safety by providing such an arrangement that braking lock is inhibited when a lever of an automatic transmission is set into a drive range even though braking is manipulated. CONSTITUTION:When an automatic lever 1 of an automatic transmission is turned about a fulcrum 2 toward a drive position 3 from a parking position 13 or a neutral position 14, a tension force is effected in the releasing direction of a locking pin 6 through the intermediary of a wire 4, a spring 7 and a clamp 8, but is absorbed by resilient deformation of the spring 7 so that the locking pin 6 is not released. Further, when the lock release lever 9 is pulled, a side brake is released, and thereafter, the locking pin 6 is shifted away from its locking position by the spring 7 so that the locking is not effected even though a side brake pedal 10 is depressed, thereby serving as a foot brake. When the lever 1 is returned to the neutral position 14, the spring 7 is recovered so that the locking pin 6 is moved to a lockable position with respect to a stationary member 11, and is secured when the pedal 10 is depressed. Thereby it is possible to enhance the safety.
