Inventor: KANETANI FUMIO
IPC: G08B25/08
Filed: 1995-04-05
Abstract: PURPOSE: To allow a master set to inform a current state clearly by outputting a prescribed message to a slave set called newly from the master set. CONSTITUTION: The telephone system has a master set 1 and plural slave sets 2-1-2-n connecting to the master set 1 through speech lines LN1 -LNn .

Title: Elevator controller
Inventor: TAKAHASHI EIJI
IPC: B66B1/18
Filed: 1988-04-27
Abstract: PURPOSE:To improve the service of an elevator by registering hall call signals as those to an elevator capable of serving to various floors when the signals are judged as destination floor calls to various floors, and providing a second operation control means for making an elevator operate to various floors in response to the hall call signals. CONSTITUTION:When a destination floor push botton 8 to BF hall is for example operated by a waiting person at 3F hall, the hall call signal generated by a hall call generator 4 is registered by a hall call register 11. When this hall call signal is judged as the hall call by the operation of destination floor push botton 8 to the BF hall by a judging part 12 of a hall call response elevator selector 12, this signal is registered at a response elevator selecting part 12b and No.1 elevator is assigned, and the output is given to an operation control part 14 to make the box of this elevator respond to the hall call generator 4. In this way no other elevators respond to the hall call from 3F and therefore no elevator change is given to the waiting person.

Title: Molding sand for shell mold
Inventor: MATSUDA TAKEO
IPC: B22C1/00
Filed: 1986-05-09
Abstract: PURPOSE:To prevent the mold cracking and to reduce the cost by adding slag having the specific wt% of MgO, SiO2, Al2O3, FeO, CaO, etc., respectively to silica sand at prescribed adding range %, to compose a molding sand. CONSTITUTION:The molding sand for shell molding is formed by adding ferro- nickel ore smelting slag composing of 27-33% MgO, 48-58% SiO2, 1-3% Al2O3, 5-11% FeO, 4-6% CaO and remaining part of impurities to the silica sand at 15-70% adding ratio. This slag composition has almost the same coefficient of linear expansion as olivine sand's and so, it has almost the same coefficient of thermal expansion and is prevented from the mold cracking at the time of casting. And, as gas generating volume is reduced caused by slag composition, prevention of rough surface and carburization is effectively executed. Further, as the slag is gotten at low cost, the cost of the molding sand is remarkably reduced.

Title: Energization transfer-type recording head
Inventor: NAKAZAWA MASAFUMI
IPC: B41J2/325
Filed: 1988-04-27
Abstract: PURPOSE:To prevent a shortcircuiting between recording electrodes and the backward movement of the recording electrodes by forming a patterned groove for recording electrodes by carving a recording head substrate and thereby providing the recording electrode which is thinner than the depth of a recessed groove. CONSTITUTION:A plurality of recessed grooves of 30mum in width and 10mum in depth are formed at a specified interval by carving the surface of a substrate 2 of alumina ceramic using a dicing machine. In this way, a patterned groove for a recording electrode is prepared, then electroless Cu plating is applied to the surface of the substrate 2 in the depth of 2mum, and a pattern for the recording electrode of the non-electrolytic Cu plated layer 4 is formed at the bottom of the patterned groove for the recording electrode consisting of a plurality of recessed grooves 3 using photoetching technique. After this, a hard Cr plating is allowed to deposit in the depth of about 5mum on the surface of this energization electrode as a recording electrode 5. It is desirable to differentiate the depth of adjacent recessed grooves 3 and thereby extend the distance between the adjacent recording electrodes so that an electric discharge hardly occurs.

Title: Asymmetrical cmosfield effect transistor
Inventor: SAMIYUERU SHII JIYOOYA
IPC: H01L29/78
Filed: 1990-04-23
Abstract: PURPOSE: To obtains an n-channel field effect transistor having a perfect drain feature by selectively metallizing the source/drain area of a p-channel transistor by reducing the number of photolithographic masks and selectively refining an n-channel transistor having a lightly-doped drain structure. CONSTITUTION: When a substrate 1 is oxidized in wet oxygen, the thickness of an oxide 7 formed on the surface of the substrate 1 becomes markedly smaller than those of oxides 8, 9, 11, and 12 grown on the side and top faces of polysilicon electrodes 4 and 6. Then a photoresist 13 is patterned. When the photoresist 13 is patterned, the gate electrode and source/drain area of a p-channel transistor 16 are exposed, but the gate electrode and source-drain area of an n-channel field effect transistor 14 are covered with the photoresist 13. The source/drain area 17 of the transistor 16 is formed in alignment with the gate electrode 4. The source/drain area 17 is formed by implanting p-type ions 18 into the substrate 1 through the thin oxide 7, and the photoresist 13 masks the n-channel transistor 14.  Since the implantation is performed through the thin oxide 7, the silicon surface of the substrate is protected from damages caused by the implantation.

Title: Air/fuel ratio control device of engine
Inventor: MOTOITSUTA YOSHINORI
IPC: F02D31/00
Filed: 1980-07-30
Abstract: PURPOSE: To prevent the air/fuel ratio from changing to the lean side by providing a correction device to increase the fuel when the opening of carburettor throttle valve exceeds the preset value and it is sensed by an idling revolutions control device which is to hold the idling revolutions constant.  
     CONSTITUTION: When the number of revolution of an engine becomes lower than the set value, the signal from a rotation sensor 18 will generate a pulse signal from a control circuit 19. An actuator 17 is put into operation by this signal to control the duty ratio. On the other hand, the output (d) of a circuit L 1  to integrate the signal from the rotation sensor 18 in control circuit 19 becomes a value corresponding to the opening of a throttle valve 3g. Output (f) is given by the circuit R 1  as reference signal for sensing if this value has attained a certain specified value. When the order of magnitude between two signals (d) and (f) is inverted, the correction signal (h) will permit the actuator 15 to shut an air bleed 10 to increase fuel supply from a float chamber 3a. Thus the air/fuel ratio of the mixture can be concentrated.
