IPC: E04B9/00
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To effectively lower the noise level of a low frequency range in heavy weight source floor impact sound by making a ceiling material provided under a ceiling slab-to have a resonance sound absorbing mechanism. SOLUTION: In a ceiling construction in which a ceiling material 2 is provided under a ceiling slab 1 made of a concrete slab and the like, the ceiling material 2 is provided with a resonance sound absorbing mechanism such as a resonator. This resonance sound absorbing mechanism 3 is constructed so that the base end side of a head part having an opening part on one end side is connected to a main body part, and the communicating passage in the head part is communicated to the hollow part in the main body part. By this resonance sound absorbing mechanism 3, a resonance phenomenon due to the mass of the head part and the air spring component in the hollow part of the main body part is utilized, and standing wave in a room generated by heavy weight source floor impact is reduced.  Consequently, a noise level in the low frequency range to be exceedingly problems in heavy weight source floor impact sound can be effectively reduced.

Title: Self-diagnostic method for insulation resistance measuring device
Inventor: YAMAMOTO HIROSHI
IPC: G01R31/02
Filed: 1989-12-22
Abstract: PURPOSE:To measure the insulation resistance of cable in a live-line state by providing a drive detecting current transformer between a power amplification part and a transformer for injection in the main body of a device, and applying a detected primary winding current of the transformer for injection to a current transformer through a self-diagnostic switch. CONSTITUTION:When the transformer 1 for injection is normally connected, a driving current of transformer for injection flows from the power amplification part 2 and a signal is generated at the secondary side of drive detecting current transformer 3. This signal is amplified in a self-diagnostic amplification part 4 and applied to the secondary winding of leakage detecting current transformer 6 through the self- diagnostic switch 5. In the case the transformer 1 for injection is not provided, the driving current does not flow at the time when the primary winding is disconnected, and a voltage is not impressed on the secondary winding of leakage detector even if the self-diagnostic switch 5 is depressed. If the number of winding turns for primary and secondary windings of the driving detecting current transformer 3 is selected, the self-diagnostic amplification part 4 can be excluded. By this constitution, the self-diagnosis can be made for a measuring device of the insulating state including the connection state of transformer 1 for injection.

Title: Kana (japanese syllabary)/kanji (chinese character) system/method
Inventor: TADANO MASAYOSHI
IPC: G06F17/27
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To execute re-conversion after the decision of KANA/KANJI conversion. SOLUTION: A re-conversion key (it can be similar to a conversion key) is depressed by adjusting a cursor to a clause 'seigi' which is to be re- converted. The position of the cursor can be placed just before a clause to be re-converted. A clause to be noticed 20 is re-converted and a homophonic conversion candidate as its result is shown like a list 22. Since a reading 'seigi' has a high probability (likelihood) in 'seigi', conversion candidates against the reading 'seigi' are shown as shown in the reading 24. Thus, objective 'seigi' does not exist in the list of the conversion candidates. When an inverted triangle is displayed in such a case, the list 26 of all the readings on the clause 'seigi wa' can be displayed if the side of the reading 24 is clicked. When the reading is selected, the conversion candidate on the reading is displayed.

Abstract: PROBLEM TO BE SOLVED: To provide a paging method and a system for a communication unit in a packet data communication system where the number of failed paging times is reduced so as to enhance the use efficiency of a radio communication resource. SOLUTION: Stationary infra-structures 101, 103, 111-119 transmit a paging message to one communication unit 110 among communication units. The communication unit 110 transmits an affirmative reply in response to reception of the paging message. In the case that the stationary infra-structures 101, 103, 111-119 cannot receive the affirmative reply within a prescribed wait period, the stationary infra-structures 101, 103, 111-119 transmit again the paging message after awaiting the lapse of a back-off period at least. The temporal length of this back-off period depends on the quantity of an existing system behavior pattern.
