Title: Photo-plate for tight attach printing and its method of using
Inventor: SHIBAOKA YOSHIAKI
IPC: G03B27/02
Filed: 1993-07-13
Abstract: PURPOSE:To make smooth air bleeding and enhance the pattern printing accuracy by laying spheres on a printig plate, and giving different diameters between the central part and peripheral zone so that the diameter gradually varies from the center to the periphery in steps. CONSTITUTION:A printing plate 10 and a metal plate 70 as material to lead frame are set in a printing frame 80, and a tight attached condition is generated by means of air bleeding made by a vacuum pump, see the attached illustration. Spheres are laid on the oversurface of a printing plate 10, wherein the diameter is greater in the central part to reduce gradually toward the periphery in steps. Thereby the spheres in the central part having a greater diameter function so as to correct the deflection of the plate 10, and air stagnation in the center becomes less even prior to air bleeding. Because a sufficient air bleeding passage is secured by these spheres in the arrangement as described, the air bleeding operation can be done effectively, and a high performance of tight attaching between the plate 10 and metal plate 70 is achieved.

Title: Analog switch
Inventor: SESHIMOTO AKIRA
IPC: H03K17/60
Filed: 1984-09-18
Abstract: PURPOSE:To decrease a signal loss and to prevent the titled switch from the effect of the impedance of a signal source by using a two-way switching transistor (TR) whose emitter and collector are formed in the same shape. CONSTITUTION:A constant current I from constant current sources 8, 9 is fed to the emitter of two-way switching TRs Q3, Q4. Further, a constant current 2I is absorbed from a base by a constant electric current source 10. The constant current sources 8-10 form independently of drive circuits from an input terminal 2 and an output terminal 1. The on/off of the TRQ3, Q4 is controlled by using a control signal applied to a control terminal 11 and turning on/off the constant current sources 8-10. Since the analog switch is formed in this way, the signal loss is reduced. Since the drive circuit is independently of the input and output terminals, the switch is prevented from the effect of the impedance of the signal source.
