An inertia force sensor with a damper. The damper includes a cantilever for a movable part disposed in a movable electrode protruding therefrom, and a cantilever for a fixed part disposed in a support portion for the movable part or a support portion for the fixed part and protruding therefrom. The damper allows the cantilever for the movable part and the cantilever for the fixed part to contact each other before the movable electrode contacts the support portion for the movable part and the support portion for the fixed part. As a result, it is possible to prevent a stopper from being damaged and to improve the reliability of the sensor.

A thermo-sensitive flow rate sensor that comprises a plate-like substrate, a part of which is removed so that a space is provided therein, a diaphragm portion formed like a thin layer above the space in such a manner as to be integral with the plate-like substrate, and a heating element constituted by a thermo-sensitive electrically resistant film formed on the diaphragm. Plural holes penetrating the diaphragm portion are bored in an outer peripheral portion of the heating element. Each of the plurality of holes is shaped in such a way as to have obtuse corner portions or to have substantially no corner portions. The thermo-sensitive flow rate sensor measures the flow rate of a fluid, which is to be measured, according to an amount of heat transferred to the fluid from a part heated by energizing the heating element.

A pressure sensor of the present invention comprises a diaphragm 6 having a first surface which receives pressure and a thermal detecting portion 3 with a heat sensitive portion disposed as to oppose the diaphragm through a spacer, wherein displacement values of the diaphragm owing to variations in pressure are detected at the thermal detecting portion as variation values of thermal equilibrium state. With this arrangement, a surface of the diaphragm which directly receives pressure from measuring fluid does not need to undergo film forming or photolithographic processes whereby main portions of thermal pressure detecting elements might be formed onto a silicon substrate by large quantities in a lump sum through simple manufacturing processes so that it is possible to improve accuracy and reliability of the thermal pressure detecting elements and to obtain a pressure sensor of low cost.
摘要:
In an oil-operated tensioner, oil from s reservoir formed in the tensioner housing passes through a check valve to a chamber behind a spring-urged plunger, which protrudes from the housing to maintain tension in a chain or belt. Instead of the usual press-fit cup for closing the opening of the reservoir, a flat or convex cover plate is fixed to the housing for closing the opening in the reservoir.
摘要:
In a machine, such as an internal combustion engine, in which a chain is used to transmit rotating power from one shaft to another, the chain is situated in an oil-tight chain compartment which is separated from other lubricant containing spaces so that lubricating oil in the other spaces cannot flow directly into the lubricating oil in the chain compartment. Contamination of the chain lubricant is avoided, and the useful life of the chain is increased. In a first embodiment, a separate quantity of oil is situated in the chain compartment. In a second embodiment, the chain lubricating oil is recirculated in the chain compartment by a dedicated pump. In a third embodiment, filtered engine oil is delivered to the chain compartment through a passage in a shaft, and through a port in a chain sprocket on the shaft.

摘要:
A pressure sensor includes a diaphragm having a first surface receiving pressure, and a first thermal detection section opposed to a central section of the diaphragm through a spacer and having a thermo-sensitive resistance section, and a second thermal detection section opposed to an end section of the diaphragm and having a thermo-sensitive resistance section, wherein the first thermo-sensitive resistance section and second thermo-sensitive resistance section are connected to independent, adjustable constant-current sources, respectively, and are connected to a differential amplifier which amplifies a difference between (i) a voltage of the first thermal detection section, which detects a displacement quantity of the diaphragm due to pressure change as a displacement quantity of a thermal equilibrium state by the thermal detection section, and (ii) a voltage of the second thermal detection section, which does not change according to pressure. The sensor can measure pressure with high accuracy.
摘要:
A magneto-optic recording system uses a unit recording medium having on a substrate a first magnetic layer whose Curie temperature is low and also having on the first magnetic layer a second magnetic layer whose Curie temperature is high. The system heats a spot on the medium with a heating device. The system may employ two such unit recording media, each having the second magnetic layer magnetized in one direction. The two unit recording media are superposed on each other and formed integrally so as to obtain a magneto-optic recording medium in which the amount of information recorded and the recording speed are doubled. In addition, a light-emitting device and a magnetic field generator are added to the magneto-optic recording medium to obtain a compact magneto-optic recording system with a low level of power consumption.

摘要:
A magneto-optic recording medium has a cartridge provided with a magnetization direction indicating portion for indicating the direction of magnetization of a second magnetic layer. Alternatively, the direction of magnetization of the second magnetic layer is recorded in advance in the first magnetic layer. The direction of magnetization of the second magnetic layer indicated or recorded is detected and recognized. A magnetic field oriented in an opposite direction to the direction of magnetization detected is imparted to the magneto-optic recording medium. Alternatively, predetermined information is recorded in the first magnetic layer, the direction of magnetization of the second magnetic layer is detected on the basis of a signal reproducing that information, and the direction of a magnetic field to be applied to the magneto-optic recording medium is set on the basis of the direction of magnetization thus detected. In addition, the direction of the magnetic field to be applied to the magneto-optic recording medium is set and the output of a light beam is changed on the basis of the direction of the second magnetic layer detected.
