Title: Damped structure
Inventor: HARA MICHIHIKO
IPC: E04H9/02
Filed: 1994-02-08
Abstract: PURPOSE:To provide a damped structure that is easy to design and produces a high damping effect. CONSTITUTION:A dummy structure B, given a different vibration characteristic from that of a structure main body A by reducing its rigidity relatively, is set up near and parallel to the structure main body A that is a subject for damping. The structure main body A and the dummy structure B are connected together at mid-height by a connecting member C such as a horizontal beam to constitute a coupled system, wherein the dummy structure B absorbs the vibration of the structure main body A in an earthquake. The dummy structure B is an auxiliary structure that is adapted to absorb vibrations, is given strength such that collapse can be prevented, and is reusbale through restoration if greatly damaged.

Title: Circuit for controlling temperature of oven
Inventor: AMANO TSUNEHISA
IPC: F23N5/14
Filed: 1983-01-31
Abstract: PURPOSE:To make precise temperature control possible, and to prevent yeast fungi from dying even if change-over means becomes out of order, by changing the output property of a temperature detecting circuit over to a second temperature/electric potential output property by first change-over means when cooking that uses yeast is set so that the temperature is controlled using a steep part of the electric potential/temperature gradient. CONSTITUTION:Since in case of high temperature cooking the steep gradient part P1a of the first property P1 is used to control the temperature and in case of cooking that uses yeast the steep gradient part P2a of the second property P2 is use to control the temperature, the change in the room temperature against the change in the output of a setting circuit (B) can be minimized over a wide temperature range and precise temperature control becomes possible. When cooking that uses yeast is set and a change-over switch SW becomes out of order, since the detected output becomes the first property P1 or the set output has been lowered to step outputs Q2a, Q2b, its OFF set value Q2b would not intersect with the first property P1, and therefore a comparator CP1 would not issue a combustion signal for a burner.

Abstract: PURPOSE:To surely prevent a head attraction phenomenon in a simple production process by using a head attraction prevention mechanism to limit the head space before a recording medium is inserted, then releasing the limit of the head space when the recording medium is inserted. CONSTITUTION:A head sucking prevention mechanism 20 contains a stopper member 22 which can freely rotate with a fixed shaft 21 defined as a fulcrum and a spring member 23 which always energizes the member 22 so that the tip part of the member 22 is set opposite to a head arm 13. The arm 13 is attached to a carriage 11 via a plate spring 14. The member 22 prevents the attraction states of an S0 head 10 and an S1 and 12 before a recording medium is loaded. In such a case, a prescribed space is kept between both heads 10 and 12. At the same time, the carriage 11 is detached from the arm 13 in accordance with insertion of the recording medium. Then the mechanism 20 releases the shift limit of the arm 13 in the loading direction. Thus, it is possible to surely prevent the attraction phenomena of both heads 10 and 12.
