Title: Manufacture of resin encapsulating nozzle of semiconductor chip and optical sensor chip
Inventor: SAGAMI YOSUKE
IPC: H01L21/56
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To take out a large number of chips by having the surface curve recessed and smoothly from an injection opening to an opening in the inner surface of at housing section. SOLUTION: Smooth and concave inner surface of a housing is enlarged forward and tapered from an injection inlet to an outlet. Enlargement of the housing is most preferably set, such that (ϕ-ϕ1 )/H lies in the range of 0.25-0.6, where H is the distance from the injection outlet to an ejection opening plate, ϕis the inside diameter of the opening, and ϕ1 is the inside diameter of the injection outlet. Furthermore, L/(ϕ2 -ϕ1 ) is most preferably set in the range of 11-22, where ϕ2 is the inside diameter of the injection inlet, L is the distance from the injection inlet to the outlet, and ϕ2 >ϕ1 . Since encapsulating resin can be ejected at a uniform pressure from a large number of needles, quality, reliability and productivity of resin encapsulating process for semiconductor chip can be improved.

Title: Sensing method of vehicle for vehicle gate unit
Inventor: ISHIDA TAMOTSU
IPC: G01V3/10
Filed: 1984-07-03
Abstract: PURPOSE:To enable the sensing of the presence of a vehicle not affected by any external factor such as temperature, by comparing the oscillation frequency during the passage of the vehicle with a reference obtained by adding a specified number to the oscillation frequency before access of the vehicle to reduce the number of required oscillators of a vehicle detection means to one. CONSTITUTION:The number of data outputted from a data latch section 10 is compared with the reference outputted from a total adder 16 and when it is larger than the reference, H is outputted while when it is smaller than the reference, L is outputted. The outputting of H from a comparator 17 means the sensing of a vehicle and a counter 11 is reset while the strobe of a latch strobe control 1 is forbidden to hold the reference. As the vehicle passes, the number of data at the data latch section 10 decreases and the output of the comparator 17 goes to L. The counter 11 restarts counting and the latch strobe control 12 outputs a signal at a specified time interval to rewrite the number of data at an auxiliary latch section 13 and a main latch section 14. Thus, the presence of a vehicle can be sensed in noway affect by any external factor such as temperature.
