Title: Manufacture of chip filter
Inventor: IKEDA YOSHIHIRO
IPC: H03H3/02
Filed: 1993-03-29
Abstract: PURPOSE:To manufacture a chip filter capable of exactly coating the upper and lower plane of a piezoelectric element with a coating material. CONSTITUTION:The piezoelectric element 14 is arranged horizontally keeping a gap between the inner wall of a case 12 in the inside of a case 12. The piezoelectric element 14 is fixed on the case 12 with conductive paste 16. Furthermore, the coating material 18 is supplied by discharging on the conductive paste 16 by a dispenser 22. A part of supplied coating material 18 flows in the gap between the piezoelectric element 14 and the case 12 from the conductive paste 22. The coating material 18 in the gap further flows in the longitudinal direction along the gap. Also, another coating material flows on the upper plane of the piezoelectric element. The coating material that flows in the upper plane of the piezo-electric element further flows on the upper plane of the piezoelec-trio element, and arrives at the gap between the piezoelectric element and the case. The coating material meanders on the lower plane of the piezoelectric element 14 by capillarity occurring in the gap between the piezoelectric element 14 and the case 12.

Title: Method for dry etching aluminum
Inventor: TSUKADA TSUTOMU
IPC: C23F4/00
Filed: 1982-06-05
Abstract: PURPOSE:To increase etching speed and selectivity to a resist film and to reduce etching residue on a base material in the titled method using a reactive ionic etching apparatus, by mixing a reactive gaseous mixture with oxygen. CONSTITUTION:An Al is dry etched using a reactive ionic etching apparatus in which plasma is generated between parallel flat electrodes by introducing a reactive gas. At this time, a gaseous mixture contg. at least BCl3, CCl4 and O2 is used as the reactive gas. The etching speed is made higher than that of a conventional method using a gaseous mixture of BCl3 with CCl4, and the selectivity to a resist film is increased when the volume ratio of CCl4/BCl3 is high. A gaseous mixture having the high volume ratio of CCl4/BCl3 can not be used so far. Eetching residue can be removed when O2 is not contained in large quantities.

Title: Detecting system for runaway of processor
Inventor: GOTOU MITSUO
IPC: G06F11/30
Filed: 1983-06-01
Abstract: PURPOSE:To simplify the constitution of a runaway detecting circuit by detecting the runaway of a processor of one side of a multi-processor system by a processor of the other side. CONSTITUTION:A local control (LP) program starts a global (GP) monitor program within a fixed time T1. Thus this monitor program compares the contents of a GP monitor flag area 9 with those of an LP monitor flag area 10. Then the contents of the area 10 are inverted if the coincidence is obtained, and at the same time a GP monitor timer area 11 is reset. If no coincidence is obtained, it is checked whether the value of the area 11 exceeds the GP timer value T2. If the value of the area 11 exceeds the value T2, it is decided that a GP processor 7 has a runaway. At the same time, a GP control program also starts an LP monitor program every fixed time T3. Thus a runaway of a local processor 8 can be detected in the same way.

IPC: G02B5/20
Filed: 1990-04-11
Abstract: PURPOSE:To improve the visibility and to apply the optical filter excellently to a display element which is large in area or flexible by transmitting light, which is made incident at an angle of incidence within a specific range determined by the deviation distance between 1st and 2nd light shielding films and the film thickness of a transparent base body, through the transparent base body. CONSTITUTION:The 1st light shielding film 11 is constituted by forming beltlike unit films 6 with width (b) at pitches (a) and the 2nd light shield film 12 is formed in the same pattern with the 1st light shielding film 11 while shifted in position from the 1st light shielding film 11 in a direction crossing the length direction of unit films 6 and 7. Therefore, only light beams l2 and l3 within the specific incidence angle range determined by the pitch (a) of the 1st and 2nd light shielding films 11 and 12, pattern width (b), the deviation distance between the 1st and 2nd light shielding films 11 and 12, and the film thickness (t) of the transparent base 10 pass through the optical filter 5. Consequently, the visibility of a large-area display device is improved and the optical filter is applicable even to the flexible display element without spoiling the flexibility.

Title: House
Inventor: OGINO MITSUHIKO
IPC: F24F3/00
Filed: 1989-04-14
Abstract: PURPOSE:To efficiently perform the space cooling and heating, perform a uniform space heating and provide a healthy environment by forming a heat insulation layer in the roof and exterior wall, laying a heating medium pipe in the earth floor to make it an earth floor heating section, disposing an air supply opening and an air discharge opening in the living space, and routing the air between the living space and the under-the-floor space through a heat exchanger. CONSTITUTION:During the winter season, the air taken in from outside goes through a heat exchanger 23 before being released to the under-the-floor space 3. Because the under-the-floor space 3 is pressurised by the heating effect of the earth floor heating section 8 and the air supplied from the heat exchanger 23, the air rises in the wall space 7 delimited by a heat insulation layer 4 to the attic space 1 and the living space 2 through an air supply opening 20. The air which moved into the living space 2 is diffused and ultimately discharged outside from an air discharge opening 22 through the heat exchanger 23. In the heat exchanger 23, the air taken in from outside and the air discharged to the outside exchange heat. In the summer season, the ventilation is performed through the heat exchanger 23 even when a space cooling apparatus such as air conditioner is being operated in the living space 2.

The part which is heated partially to become the normal conductor passes the magnetic flux from the permanent magnet layer 3, so the magnetic latent image is formed on the distribution of magnetic flux 5 leaking from the part of the normal conductor. Consequently, the energy efficiency at the time of writing is good and large-area writing becomes extremely easy.
