Title: Fireproof joint material
Inventor: UI TAKEHIRO
IPC: E04F13/08
Filed: 1995-05-25
Abstract: PURPOSE: To make it possible to mount a joint material easily which is excellent in workability and attain fire proofing treatment only with a single mounting work. CONSTITUTION: This fireproof joint material comprises a heat resistant plate spring and provides a pair of less whose intermittent part 21 is outwardly projected by bending or curving and holds a fin-like waterstop head 1 made of an elastic body at the tip of an elastically mountable fireproof part 2 having a locking part folded outwardly at the end. This construction makes it possible to embody a fireproof sheet where a spring board can be welded without any clearance only with a single and simple mounting work based on a push-in basis and a water tight seal where the elastic body is pressed in between the joints simultaneously. It is, therefore, possible to provide a dry type fireproof joint material which is capable of preventing the floating or falling off from the joints by locking and fixing the end of the spring board with the wall of a board or the like.

Title: Switching noise removing device
Inventor: KAWAMURA TAKESHI
IPC: G11B20/06
Filed: 1988-06-20
Abstract: PURPOSE:To decrease switching noise included in the break of a sound signal, by causing a signal to be continuous. CONSTITUTION:A reproducing FM signal from a magnetic tape is demodulated and after that, the signal is inverted by inverting means 13 and 14. Such an inverted signal is passed by a passing means such as gate circuits 15 and 16, etc., for example, only for a short time switched by a switching pulse. Then, such a passing signal is differentiated by differentiating means 17 and 18 and formed to the pulse of a reverse polarity. After that, such a formed differentiat ing signal and the reproducing FM signal are mixed by mixing means 19 and 20. Thus, direct current level difference generated in the break of the signal, is canceled and after that, the signal is continuously and smoothly connected to an output signal from next revolving magnetic heads 1 and 2. Thus, the head switching noise, which is generated when the respective revolving magnetic heads are switched, can be decteased.

Title: Double-focus optical system
Inventor: KATOU KINYA
IPC: G02B5/30
Filed: 1982-09-02
Abstract: PURPOSE:To allow any objective to form images of bodies at different positions invariably without any magnification difference by providing elements which diverge and converge the 1st and the 2nd light beams relatively, and specifying the position of the intersection of the light beams of the composite system of both elements. CONSTITUTION:The divergent element A1 diverges the light beam B2 of the 2nd image S2 more than the light beam B1 of the 1st image S1, and the convergent element A2 converges the light beam B2 more than the light beam B1; and the focal length F of the objective L0 converges the light beams B1 and B2 equally. The intersection P of both light beams is at the focal point F behind the principal axis H of the objective L0. Therefore, the angles UMo and UMe of the light beams B1 and B2 to the optical axis are equal, and the image magnification of the 1st body S1 by the light beam B1 and that of the 2nd body S2 by the light beam B2 are therefore equal to each other. Thus, the divergent element A1, convergent element A2, and optional objective are used in combination to form images of two mutually separated bodies on the same plate with equal magnification.

Title: Leak test by pouring water in condenser
Inventor: HORIBE YOSHUN
IPC: G21C17/02
Filed: 1987-06-22
Abstract: PURPOSE:To employ a thin-walled cooling pipe, by reducing the pressure difference between the outside and inside of the cooling pipe by also filling a water chamber with water at the time of a leak test by pouring water on the side of a body. CONSTITUTION:A condenser 2 is provided to the lower part of a turbine 1. At first, the access port valve 4 of a water chamber 2b is closed to fill the water chamber 2b with water by a water pouring system 8. At this time, a pump 9 is continuously operated and water is allowed to flood from an overflow system 10 to prevent the generation of the drainage from a cooling pipe 2d. Next, a body side 2 is filled with water by a water pouring system 5 to confirm the airtightness of the welded part of the body and the strength of the whole of said body. Hereupon, since definite water pressure is applied to the interior of the cooling pipe, a part of the water pressure due to the filling water on the side of the body is negated and external force of a tolerant value or more is not applied to the cooling pipe 2d. As a result, even when the thin-walled cooling pipe is used, the cooling pipe 2d is not damaged at the time of a leak test by pouring water.

Title: Method for testing refresh operation of memory whose subthreshold leakage current may be set at worst condition
Inventor: WIK THOMAS R
IPC: G11C29/50
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a method by which the respective cells of a memory array are tested with a large leakage current in order to assure that the respective memory cells of the memory array satisfy the specification of refresh intervals. SOLUTION: A memory array includes 1st and 2nd memory cell columns. The 1st memory cell column includes a 1st memory cell in which memory values are stored and the 2nd memory cell column includes a 2nd memory cell. A logic HIGH value is stored in the 1st memory cell and a logic LOW value is stored in the 2nd memory cell as memory values. Then writing bit lines connected to the 1st and 2nd memory cells are driven to be a logic LOW level for a period practically equal to a specified refresh interval to read the memory value out of the 1st memory cell. If the level of the memory value is logic HIGH, it means that the 1st memory cell operates normally. If the level of the memory value is logic LOW, it means the operation of the 1st memory cell is defective.
