Abstract: PROBLEM TO BE SOLVED: To detect the position of an object face with high accuracy by changing the light flux distribution of an objective lens system, and processing signals based on the signal changes of a light receiving sensor in response to the changes. SOLUTION: The focal position of an objective lens 100, the rotation center of a scanning mirror 500, and an illumination light source 300 are located at conjugate positions to the pupil 101 and opening aperture 430 of the objective lens 100. The secondary light source of the illumination light source 300 is invariably formed at the focal point of the objective lens 100 without depending on the inclination of the scanning mirror 500, and the pupil position of the illumination light source 300 is moved in the pupil 101 of the objective lens 100 by the scanning of the scanning mirror 500. When an object face 3000a coincides with the focal face of the objective lens 100, the position of a secondary light source image on a light receiving sensor 950 is not moved.  At the time of noncoincidence, the secondary light source image is moved according to the inclination of the scanning mirror 500. When the phase relation between the shift quantity of the secondary light source image on the light receiving sensor 950 and the scanning of the scanning mirror 500 is checked, the drift quantity and drift direction of the focal point can be detected.

Title: Measuring instrument of grain processing equipment
Inventor: IWASHITA MASAHIRO
IPC: B65G65/40
Filed: 1990-03-31
Abstract: PURPOSE:To improve the efficiency in receipt of grain by providing a conveyor means with a route switching part for switching the supply of grain to one of a plurality of measuring instruments. CONSTITUTION:When the amount of grain passing a roughing machine A6 becomes small, namely, when an increase of the supply of grain to a measuring instrument A8 is reduced, the instrument A8 supply the grain is forcedly switched to another instrument, thereby starting receipt of next grain. When a switch valve A7 is changed while the grain is not completely supplied to the instrument A8, the remaining amount of the grain supplied therebefore and left in the roughing machine A6 is added to the grain supplied next. However, a part of the gain supplied next remains in the roughing machine A6 when the supply is stopped, thus generating no measuring error. Moreover, since there is no grain left in the roughing machine A6 when the equipment is started, the amount of the grain received first is measured less by the remaining amount in the roughing machine A6. However, if the remaining amount is set beforehand, the measuring value can be corrected.

Title: Discharge lamp lighting device
Inventor: KITAMURA NORIYUKI
IPC: H02H3/08
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To perform overcurrent protection for a main switching element with a simple circuit configuration and reduce a cost by configuring such that a control circuit for performing various control such as lighting start control is separated from an overcurrent protection circuit. SOLUTION: In this discharge lamp lighting device, a control circuit 20 for performing various control such as discharge lamp start control and an overcurrent protection circuit 30 for performing overcurrent protection for a main switching element Q1 are separately provided. When a rush current occurs, a voltage between a gate and drain of the main switching element Q1 is detected with resistors R2-R4 in the overcurrent protection circuit 30. When the detected voltage exceeds a VBE voltage of an overcurrent protecting transistor Q3, the overcurrent protecting transistor Q3 is turned on to allow a flow of a collector current. As a result, a gate current (a drive signal) of the switching element Q1 is reduced to a low level, so that breaking of the main switching element Q1 due to the current can be prevented.  Because the overcurrent protection can be performed with this simple configuration, a cost of the whole device can be reduced without complicating the control circuit.

Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To obtain a dismounting apparatus by which a BGA package can be removed easily without having a bad influence on a printed-wiring board by a method wherein a heating filament is electrified. SOLUTION: First, in a state that the heating temperature of a heating filament 12 is regulated, a dismounting apparatus is arranged to be parallel with a printed-wiring board. Then, the heating filament 12 is brought into contact with solder balls in a first row out of solder balls provided ay a BGA package. Since the heating filament 12 is set to a high temperature state, the solder balls in the first row are fused. Immediately after the heating filament 12 has fused the solder balls in the first row so as to be passed through the balls, a separation thin plate 13 is interposed between the fused solder balls in the first row. Since the separation thin plate 13 is constituted of a material to which molten solder is not stuck, the heating filament 12 is soon brought into contact with solder balls in a second row.  At this time, the solder balls in the second row are fused in the same manner as the solder balls in the first row.
