Title: Air filter and method for producing same
Inventor: TALLENTIRE ALAN
IPC: B01D39/14
Filed: 1987-11-20
Abstract: A porous material (e.g. a paper 6) has pores with a range of sizes. A pore modifying agent (comprising particles 8 of a narrow size range) is selectively incorporated within the larger pores (7) to provide zones (9) of high surface area. These greatly reduce the penetrability of the material (e.g. by micro-organisms) while having relatively little effect on its air-permeability. The modifying agent (8) may be incorporated by creating a pressure difference across the material (2), and treating it with a dispersion (e.g. an aerosol) of the modifying agent (8), under conditions of low inertia, and incorporating only a small amount of the agent (8) (e.g. under 1% w/w).

Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive light shielding device which is simple in constitution and has high transmittance and large opening rate and an information transmission device, such as high-performance printer or display element, equipped with such light shielding device. SOLUTION: An opaque liquid material 4 hermetically sealed in a transparent vessel 1 is heated to evaporate by a heating means 2 disposed in the transparent vessel 1, by which the transmittance in very small light transparent regions R is increased to allow the transmission of light. On the other hand, the evaporated liquid material (air bubbles) 5 is condensed by stopping the energization to the heating means 2, by which the transmittance in the light transparent regions is lowered to selectively shut off the light. The heating means 2 is disposed on at least one inside surface of a transparent substrates 1a, 1b and are formed of transparent conductive films, by which the hindrance of the transmission of the light is averted.

Title: Latch circuit
Inventor: NAKAIZUMI KAZUO
IPC: H03K3/356
Filed: 1988-01-08
Abstract: PURPOSE:To suppress the delay in the reply time even when the level of the level shift of an output stage is decreased to decrease current consumption of a latch circuit by driving a gate of a D-FET for preventing floated output by means of an exclusive level shift. CONSTITUTION:A signal DIN goes to an H level and the inverse of DIN goes to an L level at a time t21, a CLK is at an L level and the level of a node N11 is kept to an L level and the level of a node N16 is kept to an L level. When the CLK goes to an H level at a time t22, the node N16 goes to an L level at a time t24. The signal inverse of DOUT goes to an L level at a time t26 because the discharge of an added capacitance C12 takes much time. When the node N16 approaches an L level at a time t23, the current drive capability of a D-FET Q11 is larger than that of the Q14 and the node N11 reaches an H level at a time t25. The signal of DOUT goes to an H level at a time t27 because the charge of an added capacitance C11 takes much time. When the CLK reaches an L level at a time t28, the latch data is obtained as an H level at the terminal DOUT and an L level at the terminal, inverse of DOUT.
