Title: Method and device for dicing
Inventor: ISHIGAKI KOJI
IPC: H01L21/301
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To find a correction value for the feeding amount of a blade in a non-contacting state. SOLUTION: A dicing device which dices a wafer with a blade 19 by moving the blade 19 forwards and backwards, while rotating the blade 19 after the blade 19 has been fed to a holding surface 11 of a wafer 1 is provided with a range finder 20, which measures the error ΔA of a present location 11a of the holding surface 11 from a reference location 11o, by measuring the distance to the surface 11 and a CPU 21 which measures an error B or a present location 19b of the point of the blade 19 from a reference location 19o from the feeding amount of the blade 19 until the blade 19 is detected by means of a non- contacting sensor 22.  The correction value for the feeding amount of the blade 19 is found, based on the sum of the error ΔA of the present location of the holding surface 11 from the reference location 11o and the error ΔB of the present location of the point of the blade 19 from the reference location 19o. Since the amount cut by the blade 19 into the wafer 1 can be maintained at a set value after the blade 19 has been set by correcting the feeding amount of the blade 19 with the correction value found, a prescribed cutting amount can be maintained.

Title: Lighting device for metallic vapor discharge lamp
Inventor: KUMAZAWA TOSHIHIRO
IPC: H05B41/234
Filed: 1988-02-16
Abstract: PURPOSE:To make normal lighting action possible by disposing a current control circuit consisting of a parallel circuit of a diode and a resistor outside an outer tube of a discharge lamp. CONSTITUTION:A current control circuit 6 consisting of a parallel circuit of a diode 4 and a non-flammable resistor 5 is disposed so as to be connected in series to a lamp 1 when the lamp 1 is installed. Namely the current control circuit 6 is disposed outside an outer tube of a metallic vapor discharge lamp. As a result, conventional metallic vapor discharge lamp and lighting devices are used as they are and the current control circuit 6 of the simple construction is merely interposed between them. With such a simple construction, thermal influence from the oscillation tube of the diode 4 is reduced and flickering is prevented over the entire life of the lamp 1.

Title: Paper feeder
Inventor: KAMEYAMA TOSHIAKI
IPC: G03G15/00
Filed: 1991-01-31
Abstract: PURPOSE:To smooth any movement of a paper feed tray as well as to promote the ensurization of paper feeding operation by performing the contact or separation between a separation roller and a feed roller in linkage with rotation of a tray bottom plate. CONSTITUTION:A lever 10 as a contact-separation means for a separation roller is lowered by dint of energizing force of an energizing member 6 as a tray lowering means, and when it is not set to a paper feeding position, the separation roller 7 is shifted to a lower direction separated from a contact-separation position to or from a feed roller 4. When a paper feed tray 1 is set to a specified position, an up motor 13 gets rotation whereby the paper feed tray 1 goes up by a tray bottom plate upping means, and the lever 10 makes the separation roller 7 come into contact with the feed roller 4 by dint of the specified pressing force. Therefore, since the contact-separation to or from the separation roller 7 with the feed roller 4 is performed in linkage with rotation of the tray bottom plate 5, a span of contact time between these rollers 4 and 7 is shortened, thus paper-feed setting operation can be done smoothly.

Title: Reed relay
Inventor: MIZUGUCHI YASUNARI
IPC: H01H50/44
Filed: 1991-01-31
Abstract: PURPOSE:To reduce the total self-inductance so as to enhance responsiveness of a switch by connecting in parallel a plurality of coils wound less than the winding number required to generate a desired quantity of a magnetic flux, and obtaining the necessary winding number. CONSTITUTION:A plurality of coils C1-Cn each wound less than the predetermined winding number are connected in parallel onto the circumferential surface of a reed switch 1, to thus generate a magnetic flux required for switching a contact portion 1a of the switch 1. Since each of the coils C1-Cn wound less has small self-inductance, the total self-inductance can become small even in the case of plural parallel arrangement. Consequently, it is possible to shorten a rising time from a time when the switch 2 is closed and a voltage is applied to the coils C1-Cn to a time when strength of a magnetic field is saturated. As a result. responsiveness of the reed switch can be enhanced.
