Title: Compressor for turbocharger
Inventor: HASEGAWA HIROYUKI
IPC: F02B39/00
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To increase work load of pressure conversion by extending a diffuser from an inlet portion, leading to an impeller chamber to a scroll in the radial direction, so as to define a bent portion in a flow passage extending to an outlet portion that opens to be inside of a section along the inner surface of the scroll. SOLUTION: In a compressor housing 18, when viewed in a cross section which includes an impeller shaft 14, a diffuser 22 is provided with a straight portion 22A and a bent portion 22B. The straight portion 22A extends from an inlet portion 25A which communicates with an impeller chamber 21 to a scroll 23 in the radial direction. The bent portion 22B extends along the inner surface of the scroll 23 from the outer end portion of the straight portion 22A to an outlet portion 25B, that opens to the inside of the section of the scroll 23. This constitution allows the diffuser to be elongated and work lord of pressure conversion to be increased without enlarging the outer appearance of the compressor housing.

Title: Door opening and closing device for recording medium inserting hole
Inventor: SHIBUYA YASUSHI
IPC: G11B33/02
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To drive an opening member for opening a door with a low load and moreover to prevent the occurrence of backlash between a driving body and the opening member. SOLUTION: The opening member 17 of a turning type for opening the door 13 is formed with a cam hole 17b, and a projecting part 16 of the driving body 15 is slid in this cam hole 17b. For example, under the door closing state prior to insertion of a recording medium, the projecting part 16 is elastically pressurized by an elastic member 17d in a restraining part (1) of the cam hole 27b. Therefore, a backlash is hardly generated between the driving body 15 and the opening member 17. In addition, since the opening member 17 is not energized by a spring, a driving load by the driving body 15 is lightened.

Title: Code information reader
Inventor: NISHIGUCHI OSAMU
IPC: G06K7/10
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent code information from being misread by counting matches while regarding the same code information obtained from the same scanning line as one piece of code information. SOLUTION: When a read frequency (m) recorded in a read frequency area reaches a certain value (>N), a bar code information decision part compares or retrieves pieces of bar code information by scanning lines which are stored in a bar code information area of a bar code information storage memory 24 and judges bar code information having more than one match as correct bar code information. Further, a scanning line number (n) is managed and bar code information obtained from the same scanning line is handled as one piece of bar code information even in case of a match. Therefore, even when code information is misread on only one scanning line and unreadable on other scanning lines, the number of matches of the misread code information does not increase, so the misread code information is never judged as proper code information.

Title: Magnetic recording and peproducing device
Inventor: SUZUKI YUTAKA
IPC: G11B31/00
Filed: 1991-03-20
Abstract: PURPOSE:To prevent a receiving channel of the outer equipment from erroneously being switched by locking the receiving channel of the outer equipment under video recording at the same time as the video recording start of VTR. CONSTITUTION:A control curciut 3 outputs to a traveling mechanism 1 and a recording circuit 2 a traveling start instruction and a video recording start instruction by operating a video recording key. Next when a switching circuit 5 is at a point of contact a, (normally it is selected before the video recording start with an input switching operation of the user), a circuit 3 connects a BS control terminal 11 at a positioln of a point of contact b by switching a switching circuit 12 and a BS lock signal is sent out to a BS tuner 6. After receiving the BS lock signal, the tuner 6 becomes a lock mode and a channel key operation of the body and a channel selection with a remote control signal are not received. Thus it is prevented to be switched a receiving channel of the BS tuner 6 with an erroneous operation of the user.
