Title: Sales data processor
Inventor: FUJIWARA YASUHIRO
IPC: G07G1/14
Filed: 1990-09-27
Abstract: PURPOSE:To shorten the data collection time of a master machine by providing a real-time transmission means for transmitting sales data to the master machine, transmission monitoring means, and an auxiliary storage means. CONSTITUTION:In a satellite machine 11, the success or failure of sales data transmission by the real-time transmission means is monitored by the transmission monitoring means. When the sales data transmission fails, the sales data whose transmission failed is temporarily stored in the local PLU (Price Lookup) file of the satellite machine 11 by the auxiliary storage means. In this way, sales data are transmitted from the satellite machine 11 to a master machine 10 simultaneously with sales registration at the time of the sales registration. Even if there is an error in the real-time transmission of sales data, the data is temporarily stored in the local lookup file. Thus, sales data collection time is shortened, and business becomes smooth.

Title: Rotary polygonal mirror
Inventor: TAMURA YOSHIHIRO
IPC: G02B5/09
Filed: 1985-11-20
Abstract: PURPOSE:To make a lens system compact by constituting a reflecting face of a part of a spherical face. CONSTITUTION:Since the reflecting face is constituted of a part of a spherical face, the curvature of the reflecting face in a plane orthogonal to a revolving shaft of a rotary polygonal mirror 4 and that in a plane parallel with the revolving shaft of the rotary polygonal mirror are made equal to each other, and therefore, the reflecting face is concerned in image formation of light equally in both of the plane orthogonal to the revolving shaft of the rotary polygonal mirror and the plane parallel with it. Consequently, it is unnecessary to use a lens different in curvature in planes orthogonal to and parallel with the revolving shaft of the rotary polygonal mirror in a lens system arranged in the light incidence side of the rotary polygonal mirror. Thus, the lens system is made compact.

IPC: H01S5/026
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a method for coupling members or the like which allows positioning with high accuracy and is high reliability at a low cost. SOLUTION: A case 22 and a laser diode 24 are coupled by a first adhesive 32 which is UV curable and is rapidly fixable after the case 22 and the laser diode 24 are aligned. The case 22 and the laser diode 24 are thereafter coupled by a second adhesive 34 which is thermosettable. Both are rapidly temporarily fixed by using the first adhesive 32 after the alignment, by which the mispositioning after the alignment may be prevented. Both may be thereafter fixed more securely by using the thermosetting second adhesive 34 and spending a sufficient time. The coupling processing with the lessened misalignment and high strength is thus made possible by utilizing the adhesive processing of simple work.
