Title: Lens system for deflected light beam
Inventor: SAKUMA NOBUO
IPC: G02B13/00
Filed: 1985-01-30
Abstract: PURPOSE:To form a lens system for a deflected light beam which has curvature of field corrected excellently while having a large effective angle of deflection by composing a surface inclination correction system of an ftheta lens and a correcting lens. CONSTITUTION:The ftheta lens 10 consists of two positive meniscus lenses and its effective angle of deflection is >=50 deg.. Those two meniscus lenses both have their concave surfaces opposite to a deflection point side. The correcting lens 20 is a troidal lens and arranged between the ftheta lens 10 and a surface to be scanned. This troidal lens has a surface inclination correcting function and a curvature-of-field correcting function. The ftheta lens 10 consists of the positive meniscus lenses, so a >=100 deg. effective angle of deflection can be obtained.

Title: Parallel arithmetic unit
Inventor: ASADA OSAMU
IPC: G06F17/16
Filed: 1989-01-27
Abstract: PURPOSE:To improve the computing speed by solving simultaneous linear equations based on a specific recurrence formula and also deciding a necessary real constant parameter from the estimated maximum proper value and the estimated conditional number. CONSTITUTION:The repetitive arithmetic operations are carried out based on an equation I so that simultaneous linear equations Ax=b is solved. In other words, a repetitive arithmetic means computes repetitively the equation I and gives the unknown vector x<(>K<)> obtained from each operation to a control means. The control means detects the error of the received vector x<(k)> and decides for each repetitive operation whether the allowable accuracy epsilon is satisfied or not to output the vector x<(k)> when the accuracy is satisfied for the first time. In this case, a parameter generating means produces the parameters alphaand beta based on the allowable accuracy epsilon and the repetitive computing frequency (k), the maximum proper value obtained from a maximum proper value computing means, and the initial error obtained from an initial error computing means. These obtained parameters are given to a repetitive computing means. Thus the computing speed is improved.

Title: Structure for surface mount piezoelectric component
Inventor: ANZAI FUMIO
IPC: H03H9/19
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To provide a component in which splash of solder is not deposited onto a vibrator by providing a notch to an outer circumferential part of a cover and packing a sealing member to the notch. SOLUTION: Even when splash of solder is produced by melting a solder 9 filled in an outer circumferential ridge 5 of an opening of a package 2, since a remaining notch 10 acts as a shield, the splash of the solder is not jumped into the recessed part of the package 2. Thus, the excitation of a crystal vibrator 1 provided to a bottom face of the recessed part of the package 2 is ensured. The position deviation between the package 2 and a cover 7 is not caused by fitting the wall of the cover 7 to the recessed part of the package 2. Thus, in the sealing process, a job to correct the position deviation between the package 2 and a cover 7 is not required, then the component is suitable for mass- production and the manufacture cost is reduced.
