Title: Key structure in key board
Inventor: SHIN SHIAN YUU
IPC: G06F3/02
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a key structure in a novel key board in which a key cap is stably moved downward in good balance, the electric contact of a key is stabilized, and an electric contact failure is prevented. SOLUTION: This key structure comprises a first element 20 and a second element 30 arranged as to cross each other. The first element 20 and the second element 30 are installed between a key cap 12 and a key sheet 11. Cooperatively reactive pressing parts 25, 34 are installed in the first element 20 and the second element 30, respectively. When key cap 12 is pushed down, it stably moves downward in good balance. When the key cap 12 is released from the applied push down force, due to the function of elastic rubber in the key sheet 11, it stably turns back to the original position.

IPC: B21B1/46
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To prevent the quality of a strip and the duration of casting operation from being adversely affected by the deterioration of a positive insert by forming a recessed part filing refractory material on the surface directed to a casting space side at the lower part. SOLUTION: As the refractory material 17 to be charged into the recessed part 1, a material having laminar structure such as graphite is used.

Title: Thermosensing recording method in facsimile equipment
Inventor: ONISHI TORU
IPC: H04N1/23
Filed: 1989-07-21
Abstract: PURPOSE:To obtain a print picture with less uneven density by applying prescribed print based on a print signal, giving an interrupt with an interrupt signal till a succeeding print signal is given and using the interrupt signal to apply overwrite print onto the print. CONSTITUTION:A thermal head control section 7 generates a print pulse with a print data signal and a pulse width signal from a CPU 12, receives a print request signal and sends a print output to a thermal head. An interrupt timer is started simultaneously with a print output. In the case of interrupt drive, a pulse width is set to 1/4Tsec (nearly 2.5ms) at first and printout is implemented by the print request signal. When the printout is applied, an interrupt number 1 is added to an interrupt number counter prepared in a RAM 5. When the interrupt number does not exceeds a set maximum interrupt number, the interrupt timer is again started. Thus, the interrupt is applied again after 10ms and the drive pulse having a width of 1/4Tsec is consecutive at an interval of 10ms.

Title: Brittle material and substrate using the same
Inventor: AMI NORIHIRO
IPC: C04B35/00
Filed: 1990-07-20
Abstract: PURPOSE:To effectively strengthen a material difficult to heat-treat or a material having <=0 thermal expansion coefficient by compressing the brittle material such as glass and ceramic by a compressing means to strengthen the material.

The four compressing means 11 are arranged outside an alumina substrate 12 and clamped by a screw 13 to compress the substrate 12. Since the shrinkage force is exerted on the substrate 12 in this way, a tension applied thereafter due to the flaw and bending is compensated, the net tension on the substrate 12 is reduced, the tension resistance is enhanced, and the substrate is strengthened. Furthermore, as a compressive stress is applied on the entire inside of the substrate 12, the substrate is effectively strengthened against even a serious flaw.
