Title: Thermal head
Inventor: INOUE KUNIHIRO
IPC: H01L49/02
Filed: 1982-01-20
Abstract: PURPOSE:To provide a thermal head which enables printing with a low power by preventing thermal conduction to a glazed layer with a heat resistant resin layer provided between the glazed layer and a thin film resistance layer. CONSTITUTION:For example, a coating of a heat resistant resin such as polyimide is applied entirely over a partially glazed substrate by dipping and dried. Tantalum nitride or the like is attached to the top thereof by sputtering or the like, and moreover an electrode layer made of a chrome-copper-chrome or the like is attached thereto by evaporation. Then, a required pattern is formed thereon by photoetching and after the peeling of the resist, SiO2, Ta2O5 and the like are attached thereto as protective layer by sputtering. In addition, if necessary, a photoresist is applied except for a heat generating section and after the sputtering of Ta2O5 again, the resist is peeled. Then, the heat generating section is projected slightly from the heat generating periphery with a protective film by a liftoff method.

Title: Foundation structure of underground construction
Inventor: HIRAI TAKANORI
IPC: E02D3/00
Filed: 1990-01-17
Abstract: PURPOSE:To hold down floating of an underground construction to a very little amount in case that liquefaction is caused in a sand layer by constructing a cut-off wall up to an impermeable layer, forming a drain layer inside the cut-off wall, building up an underground construction on the drain layer, and backfilling sediment. CONSTITUTION:A cut-off wall 2 is constructed in such a manner that the lower end thereof is extended to an impermeable layer C in such a position as to surround an underground construction 1 and a sand layer S just under the construction, and after digging to a depth for forming an inside drain layer D, the dug portion is backfillied with ballast or the like to form a drain layer D. Subsequently, after the underground construction 1 is built up on the drain layer, further sediment is backfilled. In the case where earthquake force or the like is applied to the sand layer S to cause liquefaction in the sand layer S in the cut-off wall 2 just under the underground construction 1, the ground in the periphery is checked from its wraparound into the cut-off wall 2, and pore water due to a very little floating is discharged to the drain layer D. Thus, the excess water pressure in the sand layer can be quickly dissipated, and a drainage work having a reliable drain effect can be executed.

Title: Controlling method of antenna mounted on satellite
Inventor: OODATE HITOSHI
IPC: H04B7/15
Filed: 1984-01-23
Abstract: PURPOSE:To reduce the switching frequency of radio channels and a switchboard by controlling a multi-beam antenna mounted on a periodically circulating satellite for communication so that respective beams are oriented to the same small zones also during the movement of the satellite on a track. CONSTITUTION: The satellite starts its service to a sevice area 7 at a position 6 and the multi-beam antenna mounted on the satellite irradiates small zones 81- 8m respectively precisely. During the period that the satellite moves on the track 5 from the position 6 through positions 6', 6'', the multi-beam antenna irradiates always the same small zones 81-8m. When the satellite passes through the position 6'', the multi-beam antenna is switched to the succeeding service area. Therefore, it is unnecessary to switch the connection of the switchboard in the satellite and to switch radio channels also in an earth station, so that the switching frequency is reduced.

Title: Recorded orchestral accompaniment device
Inventor: TAKEDA YUKIO
IPC: G11B20/02
Filed: 1985-01-21
Abstract: PURPOSE:To decrease the volume of sound relatively and reduce troubles to the environment and to expand and improve functions by providing a headphone amplifier, a changeover switch, and a resistance which limits the variable range of a main sound volume control and switching circuits properly. CONSTITUTION:Contacts D, D', and D'' of the changeover switch 16 are con nected to B, B', and B'' in addition to a way of using other than normal accom paniment. In this case, tape reproducing signals of heads 5 and 5' are applied to a tape mixing amplifier 8' through the contacts B and D, but a microphone signal from a microphone volume control 4 is not applied to a microphone tape mixing amplifier 10 because contacts A' and D' are broken, so the signal of a microphone is not listened to through a speaker. When headphones are plugged in a headphone jack 13-2 in this state, the tape playback sound and microphone reinforced sound whose mixing ratio is adjusted by the sound multi plex balance volume control 7 are listened to while mixed together. Further, the output of the microphone mixing amplifier 10 is applied to a main sound volume control 11 through the resistance 30 and contacts B'' and D'', so the sound reinforcement volume range of the speaker is limited.

Title: Anode plate for sealed lead-acid battery
Inventor: KAMIHARASHI SEIJI
IPC: H01M4/14
Filed: 1986-01-21
Abstract: PURPOSE:To increase a capacity recovery rate in a battery stored for a long period of time by adding the fine hydrophilic powder of SiO2, Al2O3, TiO2, or oxides or rate earth elements to an anode plate. CONSTITUTION:Fine hydrophilic powder is added to an anode plate. As the fine hydrophilic powder, SiO2, Al2O3, TiO2, oxides of rare earth elements, or a mixture of these materials is preferable. The particle size of these materials is 1-100mum, and the amount to be added is 0.01-3.0%. Since the hydrophilic nature of the anode plate to an electrolyte is increased, the moisture in the anode plate diffuses to the container wall and is reduced during storage over a long period of time. Even when the amount of electrolyte is reduced less than a specified value, since the anode plate has good hydrophilic nature, the electrolyte is supplied from a glass mat, and good performance is retained.

Title: Hot water heater
Inventor: SATO HIROTOSHI
IPC: F24D3/10
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To facilitate a neat arrangement of a connecting portion by reducing a step of the connecting portion which connects a radiator with a hot water pipe, wherein a soft cross-linking polyethylene pipe is used as hot water pipes which are disposed between the radiator and a plug. SOLUTION: As hot water supply and return pipes 4A, 4B which are disposed between a hot water floor heating mat 4 and a hot water plug 6, flexible crosslinked polyethylene pipes are used. Accordingly, the hot water supply and return pipes 4A, 4B have a sufficient flexibility and are light-weighted and have an excellent erosion resistance and an excellent impact resistance. Accordingly, it becomes possible to make the thickness of the hot water supply and return pipes 4A, 4B thin while these pipes 4A, 4B are almost free from cracks thus assuring no leakage of water. Due to such a construction, it is unnecessary to increase the outer diameter size of these pipes 4A, 4B exceeding their proper size relative to their inner diameter size. Rather, it becomes possible to reduce the outer diameter size of these pipes 4A, 4B compared to the conventional size.  Accordingly, the step of the connecting portion which connects the hot water floor heating mat 4 with the plug 6 can be reduced thus providing a neat arrangement of the connecting portion while assuring a stability of the hot water heating mat 4 laid in a room.

Abstract: PURPOSE:To prevent the deterioration the sound volume, the articulation, etc. of a  remote controller, by setting a tone signal for control at a low band frequency and at  the same time inverting the frequency spectrum of an audio signal to be transferred  so as to reproduce again both the audio and control tone signals at the receiving side. CONSTITUTION:An audio input signal is modulated with a subcarrier given from the  1st subcarrier oscillator 3 and through a balanced modulator 2 of the transmitting  side 21. The low-side band signal component is extracted out of a modulated wave  signal through an LPF4, and a part of the low-frequency component is deleted through an HPF5. Both the output of the HPF5 and a control tone signal supplied from a  control signal oscillator 6 are applied to a buffer amplifier 7, and the transmitting  signal is sent to a single transmission line 25. This signal is applied to a balanced  demodulator 11 of the receiving side 22, and at the same time the subcarrier given  from a subcarrier oscillator 10 is applied to the demodulator 11. Then the output of  the demodulator 11 is applied to an LPF12 to reproduce the audio signal. At the same  time, a signal is applied to a wave detector 9 via a BPF8, and a control tone signal  is delivered from the detector 9. In such a way, the deterioration of the sound volume, the articulation, etc. can be avoided for a remote controller.
