Title: Fastening device for fluid pipe
Inventor: TAKAMURA TSUYOMICHI
IPC: F16L21/06
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To facilitate handling and mounting work by connecting end parts of each fastening piece opposed to a circumferential direction to each other by a connecting means freely to detach them and freely to elastically deform them in the radial direction so as to enlarge, in a ring shape, an inner diameter having a diameter larger than an external shape of a fluid pipe. SOLUTION: Flexible pieces 11b having a thin wall are continuously arranged in parallel with each other on vertical both end parts of a base part freely to elastically deform, a size between the flexible pieces 11b is formed in the same or somewhat smaller size as the groove width of a connecting groove 2, and a lock piece 11c is continuously arranged at a tip end of the flexible piece 11b freely to engage with the stage enlarging part 12a of the connecting groove 12. Respective fastening pieces 10 are connected to each other in a ring shape by inserting a connector 11 into each connecting groove 12 formed on the end surface of the fastening piece 10 from a side direction. In this time, the inner diameter of the fastening device is elastically push-opened in a diameter enlarging direction so as to form the inner diameter some larger than the external shape of a water pipe.  It is thus possible to improve handling and mounting workability, and it is also possible to prevent a damage from generating on a part other than an assigned position.

Title: Laser bar code scanner
Inventor: BABA NOBUYUKI
IPC: G06K7/10
Filed: 1988-12-09
Abstract: PURPOSE:To enlarge the reading range of a bar code by deforming emerging light from a laser light source to a deformed beam, which is long in a main scanning direction and short in a sub scanning direction, by a beam shape deforming member. CONSTITUTION:The emerging light L is deformed to a deformed beam 6, which is long in a mains canning direction M and short in a sub scanning direction S, by a beam compressor 1 in advance. By making the light incident on a hologram disk 4 in this state, the deformed beam 6 can be radiated in a shape, which is short in the main scanning direction M and long in the sub scanning direction S, namely, along the lengthwise direction of a bar code 5 by a condensing characteristic. Thus, a rate for a defective part to be irradiated is reduced and the reading area can be enlarged. Then, since much light quantity to be detected by an optical detector can be obtained, detection sensitivity can be widely improved.

Title: Printer
Inventor: AKIYAMA MASAHIRO
IPC: B41J25/34
Filed: 1988-12-09
Abstract: PURPOSE:To make it possible to make a printer small in size while enabling execution of proper printing, by constructing a coupling means so that it maintains a gap between a print head and a platen and can change the angle of inclination of pins for printing to the direction of movement of a carrier. CONSTITUTION:A coupling means 40 is constructed so that it maintains a gap between a print head 30 and a platen 10 and also can change the angle theta of inclination of pins 31 for printing to the direction of movement of a carrier 20. An inclination angle switching device 34 is formed, including pins 32 and 33 provide on the carrier 20, projecting members 3 fixed on the frame 2 of a printer, etc. In order to adjust the angle of inclination by using the inclination angle switching device 34, the carrier 20 is moved farther than a distance of movement on the occasion of printing, so as to make the pin 32 strike on the projecting member 3. Thereby the print head 30 is rotated around a fitting pin 43 and the angle theta of inclination lessens. Since the means is so constructed as to enable the change of the angle theta of inclination as started above, the width of the print head 30 in the direction of feeding of paper, as well as the diameter of the platen 10, can be lessened. Therefore the printer can be made small in size, while proper printing can be executed.
