摘要:
A vibration-damping device with hydraulic damping has a base body, a cylindrical holder secured to the base body, and an outer cylinder press-fitted within the cylindrical holder. A vibration-damping rubber body provided with a main liquid chamber enclosing a damping liquid is disposed within the outer cylinder, and retains an inner cylinder. A thin rubber wall is disposed between the outer cylinder and the vibration-damping rubber body, and defines an auxiliary liquid chamber with the vibration-damping rubber body. This auxiliary liquid chamber communicates with the main liquid chamber by way of a throttled passageway. The cylindrical holder has a rib-like projection which radially outwardly project therefrom, and extends in a circumferential direction thereof. This projection defines a groove along an inner surface of the cylindrical holder. This groove communicates with a space defined by the outer cylinder and the thin rubber wall by way of a through hole formed in the outer cylinder, whereby the thin rubber wall freely deforms due to the flow of the damping liquid from the main liquid chamber to the auxiliary liquid chamber, and accordingly, effective vibration-damping operation can be performed.

In a projection cathode ray tube device in which a projection cathode ray tube and a projection lens assembly are coupled and held by a coupler, superior focus characteristics and high resolution are realized by eliminating the deviation between the center of the phosphor screen of the cathode ray tube and the center of the lens assembly. In the cathode ray tube, each of the outside and inside surfaces of a faceplate is formed as a spherical convex surface which is curved toward an electron gun.

The present invention aims at maintaining the high focusing performance at a low deflection power in a single-beam projection tube which is used as a projection type TV receiver or a projector and is operated at a high voltage and with a high current. The neck outer diameter of a portion on which a deflection yoke is mounted is made smaller than the neck outer diameter of a portion which accommodates an electron gun. The maximum anode voltage of the projection tube is set to equal to or more than 25 kV and the maximum beam current is set to equal to or more than 4 mA

A vibration-damping device capable of reducing the transmission of noise caused by a water pump of a hybrid vehicle, for example, to a vehicle compartment. The vibration-damping device includes a cushion member, a pump mounting member, and an elastic support member. The cushion member supports the pump, and includes holding portions each with a slit formed between an upper and lower surface thereof for insertion therein of end edges of a pump extension member that extends from the pump. The pump mounting member includes inverted L-shaped cross-section retaining portions provided on an upper surface thereof, the supporting portions being disposed between the retaining portions and the upper surface of the pump mounting member to retain the cushion member to the pump mounting member. The elastic support member engages a lower side of the pump to provide support against lateral deflection of the pump.

A method for producing a cylindrical bushing with hydraulic damping includes the steps of preparing an internal ring having an elliptical cross-section including a major axis and a minor axis, disposing within the internal ring a vibration-damping rubber block through which an inner cylinder coaxially penetrates and which has wall portions for defining a liquid chamber, so that the wall portions extend along the minor axis of the internal ring; deforming the internal ring so as to have a circular cross-section; and press-fitting the deformed internal ring into an outer cylinder.

A projection picture tube includes a bulb, a sealing chamber disposed in contact with a front surface of a phosphor screen panel of the bulb and sealed with a liquid coolant, and a holding mechanism for holding the sealing chamber by the bulb. The sealing chamber includes a transparent member disposed in front of the phosphor screen panel to be spaced apart therefrom, a heat dissipation member which is disposed between the transparent member and the phosphor screen panel and part of which is in contact with the liquid coolant sealed in the sealing chamber, seal members respectively disposed between the heat dissipation member and the phosphor screen panel and between the heat dissipation member and the transparent member, and a holding piece for holding the transparent member on the heat dissipation member. The holding mechanism is coupled to the heat dissipation member.

A method is provided for creating a binary-coding pattern to be used in binary-coding a multi-value image. The method includes the steps of: creating a basic pattern shape of the prospective binary-coding pattern by a first arithmetic operation; determining the sequence of lighting pixels composing such basic pattern by a second arithmetic operation; and creating a rectangular pattern, which serves as the prospective binary-coding pattern, based on the resultant basic pattern. Hereby, it is possible to automatically create a centralized type of binary-coding pattern, and also it is possible to facilitate creating a minimum-sized binary-coding pattern.
