Title: Both end free type bending crystal resonator
Inventor: KAWASHIMA HIROFUMI
IPC: H03H9/19
Filed: 1989-12-22
Abstract: PURPOSE:To attain miniaturization and to reduce leakage of vibration by connecting a vibrator to a support at a node of a vibration part via a bridge part and integrating them by the etching method. CONSTITUTION:A vibrator 1 consists of a vibration part 2 and a support 3 via a bridge part 4 and they are integrated by the etching method. Since the 1st bridge part 4 is a node of vibration, the displacement is almost zero and the energy of the vibration part is not almost propagated to the 1st frame part 5. Simultaneously, the vibrator 1 constitutes a 2nd frame 7 with the 1st frame 5 via a 2nd bridge part 6 and they are supported by a mount part 8. Thus, a bending crystal resonator with small size without leakage of vibration is realized.

Title: Indoor ventilation
Inventor: HORI MAKOTO
IPC: F24F7/06
Filed: 1987-12-29
Abstract: PURPOSE:To prevent a north side room from forming condensed dew in the wintertime, and to make use of a bathroom even as a drying room by sufficiently ventilating rooms in a house with the external air. CONSTITUTION:After warm air in a south side room 16 or in a bathroom 14 has been dehumidified by a dehumidifying filter 66 in the wintertime, the warm air is, if necessary, heated by a heater 68 and sent into a north side room 12. As a result, the formation of condensed dew and/or the gathering of mold in the north side room 12 can be restricted without particularly actuating a heating apparatus and the like. Further, if the air in the bathroom is circulated by means of the dehumidifying filter 66 and the heater 68, the bathroom 14 can also be used as a drying room. Consequently, the formation of condensed dew and/or the gathering of mold in a north side room 15 can be restricted without particularly actuating the heating apparatus and the like.

Title: Deterioration diagnostic method for low voltage electric wire/cable in nuclear energy facility, or the like
Inventor: KAMIMURA SEIJI
IPC: G01N25/00
Filed: 1989-12-22
Abstract: PURPOSE:To accurately decide deterioration in a live-line state by sampling an organic insulation material, measuring a thermal decomposition temperature with thermogravimetric analysis TGA, and deciding the deterioration from a corresponding relation to a decline of elongation. CONSTITUTION:Since the decline of elongation for sheath on the most outer layer caused by a composite deterioration of radioactive rays and heat is more remarkable than the deterioration of the insulator, the life is decided by the deterioration of the sheath. First of all, the organic insulation material of insulator or sheath for the actually installed wire/ cable is collected as a sample in a very small quantity allowing the current to be supplied. Then the thermal decomposition temperature for this sample is measured by the thermogravimetric analysis to decide the extent of deterioration for the wire/cable from the corresponding relation to the decline of elongation. Consequently, the analysis for sample can be performed even in the live-line state and the deterioration degree for the wire/cable can be exactly diagnosed with high reliability.
