Title: Production of foamed plate and kiln used therefor
Inventor: NAGAI SATORU
IPC: F27B9/24
Filed: 1986-05-21
Abstract: PURPOSE:To produce a foamed plate excellent in performance in high productivity by pressing the foamed plate after calcination while quenching it by direct contact of a pressurization cooling means and thereafter reraising the surface temp. of the foamed plate. CONSTITUTION:A foamable mineral raw material obtained by pelletizing the mixture of artificial glass and porous volcanic rock or the like is fed on a belt conveyor 3 from a feed hopper 4 and evened by a preliminary roller 5 to regulation it to nearly uniform thickness and sent into a kiln 1. After raising it in temp. at a temp. raising zone of the kiln 1, it is heated in a calcination zone and foamed. The foamed plate 2 is directly brought into contact with pressurization cooling rolls 6 and quickly cooled in such a range that the central part of the foamed plate 2 is not reached to softening point or below. The surface of the foamed plate 2 after quenching is reraised in temp. by atmospheric temp. Thereby the ununiformity of temp. distribution of the foamed plate 2 is eliminated and the generation of thermal stress due to quenching is relaxed. Further since both the upper and the lower side are directly pressurized by the rolls 6, uniform and sure pressurization is performed and the foamed plate excellent in performance can be produced.

Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To make a door impossible to open and possible to close at an optional position in a door checker of an automobile by attaching a selection means interlocking with a zircon knob for door lock to a braking means. SOLUTION: This door checker 4 is constituted of an arm 7 of metal plate of which one end is pivotally fitted to a pillar 2 and the other end is projected inside the door 1, and a braking mechanism 8 provided inside the door 1. The ball 12 of the braking mechanism 8 is elastically energized by a coil spring 14, braking force is applied to the arm 7 against the motion of the arm 7 in the direction of being drawn out of the door 1 by wedge effect so as to restrain the door opening motion but not to restrain the door closing motion. When a zircon knob provided on the door 1 is pulled, a link rod 17 is moved in the arrow mark F1 direction, the ball 12 is pulled off from the braking position by a releasing member 16, and hence the door can be freely opened/closed.  Furthermore, the similar mechanism can be constituted by detachably fitting a sheave with wire wound thereon to the braking means instead of the arm 7.

Patent JP-S61274507-A (JP)
Title: Variable attenuation circuit
Inventor: SHIMODA HIROMI
IPC: H03G3/10
Filed: 1985-05-30
Abstract: PURPOSE:To match the input and output terminals even when the attenuation is changed by inserting a pin diode and a capacitor between emitter follower transistor (TR) amplifiers connected in cascade. CONSTITUTION:A bias current flows to the pin diode X via resistors R12, R13 from a terminal Ib. Since the variable resistor of the diode X is connected in series between the emitter follower TR amplifiers 1, 2, when the bias current is increased (decreased) and the resistance value if decreased (increased), the attenuation is made small (large). Thus, the attenuation is controlled by the bias current. When the resistance value of the diode X is increased, a signal passing through a parallel capacitance of the diode X is a value not neglected. The deterioration of the phase characteristic due to the signal component is compensated by selecting properly the capacitance of a capacitor C11 connected in parallel between the amplifiers 1 and 2.
