Patent JP-2003150076-A (JP)
Title: Display unit
Inventor: HOTTA KOTARO
IPC: G09F9/00
Filed: 2001-11-08
Abstract: PROBLEM TO BE SOLVED: To provide a display unit which can be fitted with a flat display panel such as a liquid crystal panel so that the weight and size can be reduced. SOLUTION: The liquid crystal panel 13 is fixed to a front cover 11 by pressing the outer circumferential edge of the liquid crystal panel 13 with a center stay 14, a left stay 15, and a right stay 16 which straddle the front cover 11 along the width. The liquid crystal panel 13 need not have a fitting part, so the need for a screw receiving structure which is long along the thickness to fit the liquid crystal panel 13 to the front cover 11 with screws is eliminated to make the front cover 11 thin. A stand part where a display part containing the liquid crystal panel 13 is fitted so that it can slant and rotate is screwed directly in screw holes 20 of the center stay 14. Consequently, a firm structure which only supports the stand part is not necessary on a rear cover which can be made thin and lightweight.

Title: Method of catalytic reaction
Inventor: MAKINO KAZUHIRO
IPC: B01J8/02
Filed: 2001-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a method of catalytic reaction that does not cause a shading in a concentration of air bubbles flowing into a charging bed in the catalytic reaction method comprising steps of introducing a gas and a liquid from the lower part into a reaction zone in which a catalyst charging bed is retained in a liquid phase, allowing the resulting gas-liquid mixed phase flow in which air bubbles is finely dispersed to pass through the catalyst charging bed and discharging the liquid containing the gas and the reaction product from the upper part of the reaction zone. SOLUTION: The method of catalytic reaction regulates the flow to longitudinal direction of the gas-liquid mixed phase flow at the neighborhood of the lower surface of the charging bed by arranging a flow regulating board protruding downwardly from the lower surface of the bed at the lower part of the charging bed.

IPC: H02K5/04
Filed: 2001-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a bracket mounting structure for a motor in which a housing and an end bracket, both formed by drawing, can be accurately coupled by centering thereof. SOLUTION: The housing 2 of the motor 1 and the end bracket 5 are formed together by drawing. Three press injected engaging parts 12 are provided on the outer periphery of the opening end 4 side of the housing 2. A sidewall 15 is formed on the outer periphery of the end bracket 5, and the press injected engaging parts 12 are press injected fixedly to the inner peripheral surface of the sidewall 15. A groove 21 is recessed on the base of the sidewall 15, and the engaging parts 12 are press injected in the sidewall 15 without influence of a corner R. The housing 2 and the end bracket 5 are coupled with good central accuracy by the aligning effect of the three press injecting engaging parts 12. Thus, the bracket of a drawing product can be used instead of a die cast bracket, a cutting work is omitted, and hence the cost can be reduced.

Title: Satellite radio
Inventor: ITO TOSHIYUKI
IPC: H04B1/10
Filed: 2001-11-15
Abstract: PROBLEM TO BE SOLVED: To provide an on-vehicle satellite radio for receiving digital broadcasting from a satellite for preventing sudden volume changes which would surprise driver or the fellow passenger.

Title: Starter
Inventor: NISHIO YUKIHIRO
IPC: F02N11/08
Filed: 2001-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a constitution capable of easily arranging a fuse function in a pig tail 9a. SOLUTION: The pig tail 9a is connected to a plus side brush 10a, and is formed of a low melting point material (for example, Al) having the lowest melting point in a metallic material used in a current-carrying circuit of a motor 2, and is arranged as the fuse function in the current-carrying circuit of the motor 2. Here, a melting point of the low melting point material (Al) is higher than a heat resistant temperature of an insulating coating film of an armature coil. Thus, when a battery current is continuously carried to a starter by failure of a key switch 12, since current-carrying to an armature 6 is stopped when the pig tail 9a is fused, damage of the starter can be prevented.  Since this constitution can impart the fuse function to the pig tail 9a only by changing a construction material of the pig tail 9a to the low melting point material (Al), the fuse function can be easily set even to the starter different in output.

Filed: 2001-11-21
Abstract: PROBLEM TO BE SOLVED: To provide a transformer that can be lowered in noise level without increasing the number of parts used in a switching power unit, etc., nor the occupying areas of mounted parts. SOLUTION: This transformer is provided with a protruded section (1a) protruded from part of one ferrite core (1A) and a hole section (1b) formed in the section (1a). In this transformer, the starting and terminating end sections (3a) and (3b) of the leader line of a primary winding (3) are respectively passed through the holes (2j and 2k) of one terminal pulling-out section (2o) of a bobbin (2) after the ends (3a and 3b) are passed through the hole section (1b) of the ferrite core (1A). Since the starting and terminating end sections (3a and 3b) of the leader line of the primary winding (3) are passed through the hole section (1b) of the ferrite core (1A), a common-mode coil which suppresses conduction noise and radiation noise can be formed closely to the primary winding (3) and, accordingly, no separately provided common-mode coil is required.  Consequently, the level of produced noise can be lowered without increasing the number of parts used in the switching power unit, etc., nor the occupying areas of mounted parts.
