Title: Key fetching circuit
Inventor: OGATA YUKIHISA
IPC: G06F3/02
Filed: 1988-10-13
Abstract: PURPOSE:To perform a chattering processing by hardware by deciding the presence/absence of key input successively for a constant time. CONSTITUTION:Data with an arbitrary value is written on a key source latch 1, and the data is outputted according to a first timing signal generated at a timing circuit 3 via an output buffer 2. When a key of H level is depressed, the data on a key matrix 4 is inputted to a key latch 6 via an input buffer 5. At such a time, since the input buffer 5 also follows a second timing signal generated at the circuit 3, it is possible to take synchronism with output from the latch 1, which enables an output pin to be used in display, etc. When one of bits of the latch 6 goes to the H level, a signal showing the presence of the key input is inputted to a judging circuit 7. The circuit 7 judges the number of times of successive key input from the circuit 3 in the period of a third timing signal, and it is decided whether or not the key is depressed actually.

Filed: 1987-10-14
Abstract: PURPOSE:To measure the concentration of nuclear species in a drum can separately in a center area and a peripheral area by measuring and integrating gammarays emitted by the drum can at different collimation angles and substituting measured values in a prescribed expression. CONSTITUTION:The inside of the drum can 1 is divided into two areas, i.e. the center area 12 and peripheral area 13 outside it. A collimation angle is fixed to theta1 and the drum can 1 is rotated; and a germanium detector 2 counts the gamma rays emitted from the drum can and integrates a counted value in one turn to obtain an integrated value N1. Then the collimation angle is set to theta2 and a similar measurement is taken to obtain N2. The difference between the N1 and N2 is proportional to the radioactive nuclear species concentration Q2 in the peripheral area 13 of the drum can 1, so the nuclear species concentration Q2 in the peripheral area is estimated from the difference between said N1 and N2. In this case, the N1 is the sum of the products of the nuclear species concentration Q1 in the center area 12 and the nuclear species Q2 in the peripheral area 13, and a specific constant, so the nuclear species concentration in the drum can is measured separately in the center area and peripheral area.

IPC: A61L9/12
Filed: 1988-10-13
Abstract: PURPOSE: To provide a sprayer of an active material, making possible to improve an airtightness by composing so that only the wide side-wall of a spray substance portion has a spray nozzle. CONSTITUTION: The zone of the hollow bodies 1, 2 of a plug-seal (b) and its sealed surface are slightly reinforced by a circumferential shape. According to this feature, the sealed surface is slightly projected in comparison with the perforated zone. When the end portion of a cover element 5 is plugged into the groove of a plug-seal 2, the end portion of the cover element 5 is moved on the sealed surface projected slightly. Since the sealed surface is formed to be slightly projected, a flexible tensile force is increased, so the sealed surface in the groove of the plug-seal 2 of the hollowed bodies 1, 2 and the portion of the cover element 5 are effectively pressed each other at a closed position. Thus, these sealed surfaces are completely connected each other in any place.  By providing this projection, the cover element 5 is easily slid on the perforated zone of the hollowed body 1, 2.
