摘要:
VCO (voltage-controlled oscillator) device used for a radio unit such as a television broadcast receiver. A VCO device oscillating in a wide band of oscillation frequency and capable of realizing low power consumption is provided. VCO circuit group 4 oscillates signals of frequencies corresponding to control voltage Vt applied to frequency control voltage terminal 8. LO signal selecting means 3 selects a required output signal from VCO circuit group 4. PLL 6 frequency-divides local signal fvco selected by LO signal selecting means 3, compares a phase thereof with a phase of a reference signal and outputs a signal converted from a phase difference. Loop filter 7 smoothes the output signal from PLL 6, outputs control voltage Vt that is a frequency control voltage and outputs the local-signal selected by signal selecting means 3 to high frequency signal processing means 1.

A lever switch for vehicle, which can be produced thin and which operation is easy and ensured is provided. A lever is formed in substantially a linear shape, having at an end thereof an operating part sticking out of a case and at an other end thereof a driving part of which a middle part is movably held in the case, and a resilient push force mechanism composed of a coil spring, a pin and a saving cam is disposed between an end of a driving part of lever and an inside wall of the case, constituting the vehicle lever switch.

A variable valve control apparatus includes a variable valve timing mechanism that adjusts an actuation timing of an intake valve and an actuation timing of an exhaust valve; a variable working angle mechanism that adjusts a working angle of the intake valve; a variable valve control section that controls at least one of the variable valve timing mechanism and the variable working angle mechanism based on an engine load; and a negative pressure suppression control section. The negative pressure suppression control section suppresses a negative pressure of an inside of a cylinder when the negative pressure suppression control section determines that both of the intake valve and the exhaust valve close after an intake top dead center, based on opening conditions of the intake valve and the exhaust valve.

摘要:
In an image-recording apparatus for recording at least two images at desired positions on an image-recordable object: positions of a plurality of reference marks which are arranged in advance on the image-recordable object and common to the at least two images are detected; each of recording positions of the at least two images is corrected on the basis of the positions of the plurality of reference marks detected in the step (a); and the at least two images are recorded on the image-recordable object in an arrangement determined by the recording positions corrected in the step (b). Each of the recording positions has a positional relationship with the plurality of reference marks.

An engine component (2, 3) is disposed in front of or behind the vehicle engine with respect to the direction of vehicle travel. The component (2, 3) is covered by a protective shell (10) from an opposite direction from the engine (1). The protective shell (10) is fixed to the engine (1) by brackets (5, 6). Stoppers (11-13) in the protective shell (10) limit the displacement of the protective shell (10) towards the engine (1) from exceeding a predetermined distance. The brackets (5, 6) are provided with deformable members (5, 6A) which deform in response to an impact load applied to the protective shell (10) and guide the protective shell (10) only in a direction towards the engine (1) up to the position which is limited by the stoppers. In this manner, the protective properties of the external components (2, 3) with respect to an impact load is enhanced.

A switch apparatus has a case that includes a hollow projecting support section, a switch contact provided inside the case, and a button having a depressing section that comes into contact with the switch contact and mounted on the support section in a manner vertically movable. Furthermore, an inwardly projecting catch section is provided on the inner periphery of the support section, and an engaging hole is provided on the depressing section of the button into which the catch section is to be inserted. In this configuration, an opening on the top surface of the case is not required when manufacturing the case and the button by resin molding. As a result, a switch apparatus is obtained which is superior in resistance to water and dust and stable in operation.

A lighted switch unit having a light-shield structure at a lower end of an operating body is provided, in which an outer surface of the operating body is covered with a non-translucent covering layer, and a light-transmitting display part is formed on an upper part or side part of the body. The light-shield structure is such as an inclined part formed on an outer surface at the lower end of the operating body, with which an exposed area of a lower end of the inner surface of the operating body is made small so that an amount of a light that leaks out of a gap between the cover and the operating body is reduced. Thus, a lighted switch unit having good visibility is obtained with a simple structure.
