Title: Apparatus and method for performing efficient enclosing of smoky fog with hood
Inventor: ROBERT H MORRIS
IPC: F24F7/06
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To attain a minimum disturbed flow in an eddy chamber and further make a minimum releasing of counter-flow of air containing smoky fog by a method wherein an amount of air flowing to a discharging system through a bypass passage is changed in response to an output signal of an eddy pressure difference converter controlling an amount of air flow passing through an eddy chamber. SOLUTION: A sensing stage 44 of a dynamic differential pressure converter 45 is arranged outside a hole in a side wall 46 of a hood so as to detect a slight variation in air flow passing through the hole caused by a quite slight variation in pressure in an eddy chamber. In the case that the variation is detected, a signal is transmitted to the converter 45, amplified in a real-time basis and the signal is transferred to a feed-back control device 50. An operating device 52 to which an output of the control device 50 is transmitted moves a bypass damper 56 so as to further enter air into eddy flow and limit bypassing air passing through a bottom slot 40 and moves an outlet damper 54 in order to further open an outlet damper 54. In turn, in order to reduce an amount of air flowing into the eddy flow, the outlet slot 36 is further throated.

Title: Reset circuit
Inventor: NAKAE YOJI
IPC: H03K17/22
Filed: 1988-07-19
Abstract: PURPOSE:To surely operate the circuit even against a change showing a slow power voltage rising by providing a waveform shaping means and an RC time constant circuit retarding the signal obtained from the means. CONSTITUTION:The time till an output V1 of an RC time constant circuit 3 reaches a threshold voltage of an inverter Schmitt 4 is retarded according to the time constant when the time constant of the RC time constant circuit is selected longer than the time when the power voltage VCC does not reach its top but arrives in the steady-state soon. When the output V1 of the RC time constant circuit 3 reaches a threshold voltage, the inverter Schmitt changes the state and the output RESET changes from '1' to '0'. Thus, the initial reset signal for a digital circuit or the like is operated stably by retarding the reset signal by a prescribed time after the power voltage VCC reaches the steady-state and changing the state of the reset signal.

Abstract: PURPOSE:To take a measurement in a short time with high accuracy by interrupting luminous flux incident on a reference-side sample chamber or its transmitted luminous flux statically at high speed through fine or no vibrations. CONSTITUTION:Homogeneous light from a light source part 1 is split by a beam splitter 11 into two pieces of luminous flux, which are converged toward the reference-side sample chamber 3 and a measurement-side sample chamber 4.

Abstract: PROBLEM TO BE SOLVED: To increase the migration of hydrogen per unit time by passing hydrogen emitted from a hydrogen occulusion alloy in the rear of an alloy encapsulating chamber through the cavity of a hydrogen distributing means. SOLUTION: A container 1 is partitioned, by means of a plate filter 2, into a chamber 3 for encapsulating a hydrogen storage alloy M, and a containing chamber 6 provided with grooves 4 for migrating hydrogen. A plurality of grooves 4 are provided radially from a central hydrogen inlet/outlet 8 and hydrogen emitted from the hydrogen storage alloy M in the rear of the alloy encapsulating chamber 3 is introduced quickly to the outside through the grooves 4 with low pressure loss. On the contrary, hydrogen supplied externally through the hydrogen inlet/outlet 8 is introduced quickly to the hydrogen storage alloy M in the rear of the alloy encapsulating chamber 3 through the grooves 4 with low pressure loss. Since the migration of hydrogen per unit time is increased by means of the grooves 4, sufficient performance can be exhibited.
