Title: Underlay for ferrite calcining
IPC: C01G49/00
Filed: 1992-03-31
Abstract: PURPOSE:To provide the subject underlay capable of preventing, in the production process for Mn-Zn-based ferrites, the deterioration of their electromagnetic properties and mechanical strength due to ion diffusion, also resistant to its deterioration even if put to repeated heating and cooling. CONSTITUTION:The objective ceramic underlay with its surface provided with a Mn-Zn-based ferrite layer consisting mainly of (A) 50-60mol% of Fe2O3, (B) 20-40mol% of MnO, and (C) 10-15mol% of ZnO. With such structure, as the above ferrite layer comes into contact with a core in baking a Mn-Zn-based ferrite, the deterioration of the electromagnetic properties and mechanical strength of the ferrite due to ion diffusion can be prevented; besides, owing to the heat shielding effect of the above ferrite layer, the deterioration of the present underlay due to repeated heating and cooling can also be prevented.

Title: Combustion apparatus
Inventor: TOMIOKA MITSUHARU
IPC: F23D3/18
Filed: 1980-06-09
Abstract: PURPOSE: To increase the combusting air sucking force of the combustion apparatus such as a fan heater by a method wherein there is provided a choking section capable of giving rise to scking action on the side of a combustion gas passage due to an air stream flowing through a hot wind passage and the air stream is flowed through the choking section at a certain angle of inclination with respect to the latter.

Title: Solid-state image sensing device
Inventor: ISHIHARA YASUO
IPC: H04N5/369
Filed: 1990-03-26
Abstract: PURPOSE:To dispense with a mounting of another component like an infrared cut filter with the object of intercepting light in a prescribed wavelength range by a method wherein a film to absorb the light in the prescribed wavelength range is formed on the photodetecting surfaces of photoelectric conversion element parts. CONSTITUTION:An infrared absorption dye is mixed in a resin film 13 and the resin film 13 having superior light transmission properties is applied on the whole region including photodetecting parts of photodiode element regions 7. The formation of this dye-containing resin film 13 is performed by a method wherein a dye to absorb light in a wavelength range of 700 to 1100nm is mixed into a P-type photoresist (a novolak resin), for example, and the resist is applied on a silicon wafer with a solid- state image sensing device formed thereon by a spin coating method. After that, the resin on bonding pad parts is selectively removed by a normal photolithography technique. In case the device formed using this silicon wafer is used for a TV camera, the film 13 absorbs light in an unnecessary wavelength range before the light is incided in the element regions 7. Accordingly, an infrared cut filter being used for making spectral sensitivity characteristics meet to the standard of a reference TV becomes unnecessary.

Title: Loran c signal tracer
Inventor: KURIMURA SHIZUO
IPC: G01S1/24
Filed: 1978-06-30
Abstract: PURPOSE:To effectively accomplish the phase trace with the use of a simple device by adding the signals, which are operative to effect the step of plus ten microseconds, to a signal region for each preset time when the S/N ratio is deteriorated in a three wave detecting unit. CONSTITUTION:When the S/N ratio at a phase tracing point is deteriorated lower than a preset level, the outputs of S/N detectors 11' and 11'' take low levels so that main and auxiliary station timers 12 and 13 generate output signals a preset time later. And, OR circuits 14 and 15 admit both the signals of the aforementioned timers 12 and 13 and the signals of main and auxiliary three wave detectors 7' and 7'' to step the respective synchronous signals plus ten microseconds in an automatic manner so that the position tracing point is automatically stepped to the signal region where the S/N ratio is improved. When the S/N ratio is improved, the phase tracing point is restored. Thus, the phase tracing operation can be effectively accomplished with the use of a relatively simple device.
