Abstract:
A liquid pressure control device for an anti-lock brake system is provided. The device includes a control valve which intermittently interrupts the liquid pressure feed from a master cylinder to a wheel cylinder, a liquid pressure control piston which moves in such a manner as to control the liquid pressure to the wheel cylinder, a differential pressure-responding member which closes the control valve and moves the liquid pressure control piston in conjunction with its forward motion, a stopper arranged engageably with the differential pressure-responding member located in its initial position, and a gas pressure chamber and liquid chamber, which produce the pressure difference acting on the differential pressure-responding member. The gas pressure chamber is charged with gas, the gas pressure of which is used to return the differential pressure-responding member to its initial position during the non-braking and normal braking condition, while the liquid chamber receives an input of controlling liquid pressure which acts against the gas pressure in the gas pressure chamber during the anti-lock action, so as to make the differential pressure-responding member shift forwards. During non-braking and normal braking conditions, the stopper is engaged with the differential pressure-responding member to inhibit its forward motion and disengaged therefrom during the anti-lock action, so as to allow its forward motion.

ProblemTo obtain a drive unit integrated rotating electrical machine that makes it easier to connect power circuits and achieves not only excellent vibration resistance but also excellent heat releasing properties.Means for SolutionA drive unit integrated rotating electrical machine has a motor, a drive unit driving the motor under control and provided with power switching elements and conductors passing a current to the power switching elements, and a heat sink cooling the drive unit, which are combined into one unit. The drive unit integrated rotating electrical machine is characterized in that: the power switching elements are molded and formed into mold modules in a state in which terminals thereof are exposed; the conductors are insert-molded in a frame in a state in which terminals thereof are exposed; and the exposed terminals of the mold modules are connected to the exposed terminals of the insert-molded conductors and the mold modules are firmly fixed to the heat sink.
Abstract:
To provide a calendar mechanism equipped timepiece which, being small and thin, includes two date indicators configuring date characters which are large and easy to see. A calendar mechanism equipped timepiece of the invention includes a first date indicator which displays the ones column of the date, a second date indicator which displays the tenths column of the date, and a program wheel which enables each of the first date indicator and second date indicator to rotate intermittently. The program wheel includes program wheel teeth, first date indicator advance teeth, second date indicator advance teeth having provided at the leading ends thereof second date indicator advance fingers, and correction teeth. A configuration is such that the height of the second date indicator advance teeth is greater than the height of the first date indicator advance teeth, and the height of the first date indicator advance teeth is greater than the height of the correction teeth.
Abstract:
A method for producing a plasma display panel includes the steps of: evacuating air from a discharge space formed between a front plate and a rear plate which are substrates facing each other through piping; introducing a discharge gas into the discharge space through gas piping that branches from the piping; and recovering the discharge gas remaining in the piping system through the piping.
Abstract:
A front plate and a back plate are superposed with each other in parallel, and pressed onto each other. Moreover, the back plate and a gas-blowing jig are brought into close contact with each other. The glass pipe in which a glass fiber filter paper is placed is pressed onto the back plate, with a solid-state glass frit ring interposed therebetween. Thus, by using a glass pipe, a nitrogen, Xe, or Ne gas is supplied into the panel, or the inside of the panel is evacuated.
Abstract:
The present invention relates to fine hollow powder with a titanium oxide shell, obtained by spray drying an exfoliated titania sol, and thin flaky titanium oxide powder obtained by pulverizing the fine hollow powder, and also to processes for producing the same. The present fine hollow powder and thin flaky titanium oxide powder have a distinguished dispersibility and are useful for additives to cosmetics, pigments, paints, etc., and the present fine hollow powder also has a distinguished flowability and is useful for seed particles for flow measurement.
Abstract:
An optical processing apparatus includes an emitter for emitting light, a first light path for directing the light to a position to be processed on a workpiece, and a processing head. The processing head includes an optical system provided in the first light path, for shaping the light, a second light path having a portion shared with the first light path, the second light path directing light reflected from the workpiece, and an optical receiver for receiving the reflected light from the second light path. The optical processing apparatus further includes an actuator for changing a positional relationship between the optical system and the workpiece, a feeder for supplying a solder to the workpiece, a first shifter for moving the processing head in a first direction in parallel to an optical axis of the light emitted from the emitter, a second shifter for positioning the feeder in the first direction away from the processing head when the processing head is moved away from the workpiece by the first shifter, and a third shifter for moving the feeder against the processing head in a second direction perpendicular to the first direction while the processing head is moved by the first shifter. The optical processing apparatus allows the spot of the incident light and the position of soldering to be readily set depending on the configuration of a workpiece and can thus solder the workpiece at higher quality under soldering conditions optimized for the workpiece.
Abstract:
A multifunctional watch has a movement including first and second train wheel rotational centers each arranged at a position between a center of a main plate and an outline portion of the main plate. The first and second train wheel rotational centers are provided with respective first and second train wheel guide portions rotatably guiding respective first and second train wheel members about the respective first and second train wheel rotational centers. A first train wheel having the first train wheel member is arranged rotatably relative to the first train wheel rotational center for rotating one of the small hands only in a single direction of rotation to display the first calendar information. A second train wheel having the second train wheel member is arranged rotatably relative to the second train wheel rotational center for rotating another of the small hands only in a single direction of rotation to display the second calendar information.
