Abstract: PURPOSE:To improve the reproduction characteristic of a low sound frequency region by arranging a high-cut filter to a front side of a speaker unit so as to cut off a high frequency component of a sound wave emitted from the front side of the speaker. CONSTITUTION:A speaker equipment 1 has a speaker unit 2 and a cabinet 3 and a high cut filter 4 is fitted to a front side of the speaker unit 2 and the speaker 2 is fitted to a front side of the cabinet 3, that is, a buffle face 3a via the high-cut filter 4. Moreover, a duct 5 being an acoustic pipe in which a front end opening 5a is made open to the buffle face 3a is built in the cabinet 3. The high-cut filter 4 is formed by coupling a small diameter cylinder whose cross sectional area is small and a large diameter cylinder whose cross sectional area is large and the small diameter cylinder is used for an acoustic mass and the large diameter cylinder is used for acoustic compliance. Thus, the low sound resonance frequency is decreased to extend a reproduction band of a low frequency and a high frequency characteristic is decreased and a powerful sense rich in a low sound frequency is obtained.

Title: Preparing method for original print plate for print circuit board
Inventor: TAKAOBUSE KAZUYASU
IPC: G03F1/00
Filed: 1978-07-14
Abstract: PURPOSE: For enhanced working efficiency, basic pattern line is drawn on a base plate, from which a negative film is produced. To produce a print original film, either the original film or the negative film is riciprocally moved at right angle to the optical axis so that a line thicker than the basic line is formed.  
     CONSTITUTION: On a base plate 1 a fine circle line 2 is drawn with a pencil, etc., from which a negative film 3 with a light line 4 is produced. To expose a photosensitive original film 5 through the negative film 3, either the film 5 or 3 is finely vibrated at right angle each other so that exposed line from the circle 4 becomes thicker. Vertical, left-to-right, or circular vibration will produce the exposure 6, 7, or 8 respectively. The process eliminates the need for drawing the same patter as that required on copper foil, providing thick patterns on the photosensitive film 5 for use in copper etching of the print circuit board. Thus, the work efficiency increases.

Filed: 1993-04-14
Abstract: PURPOSE:To provide a highly reliable compressor where the abrasion of a roller due to decrease of the viscosity of the oil and the oil film break is not promoted by applying the super smooth finish to both sides of the roller. CONSTITUTION:When the ON/OFF control of a refrigerating system is conducted, the liquid coolant condensed by an evaporator 27 when the system is in OFF condition passes through a connection tube 28 when the system is started, and is sucked into a suction tube. The suction tube is cooled, the coolant in an enclosed container is liquefied on its surface, and dripped into the oil. The viscosity of the oil where the coolant is dripped is reduced, and the oil is supplied from an oil supply tube to a roller 29. The roller 29 is super-smoothly finished, and the lubricability is improved thereby, and the friction resistance between the metals is reduced. Thus, the reduction of the adhesive abrasion caused by the local break of the oil film and suppression of the deterioration of the lubrication oil caused by the local high temperature can be expected, and the abrasion of the roller 29 is not promoted.
