Patent JP-H11211075-A (JP)
Title: Vaporizing petroleum combustion apparatus
Inventor: ADACHI YOSHIHIKO
IPC: F23N5/00
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent the lift combustion which arises at weak combustion, being caused by the supply of fuel under the specified quantity or the shortage of heat back occurring at low room temperature. SOLUTION: A temperature changing means 32 detects the temperature of a carburetor, receiving the shifting signal to the side of weak combustion from a quantity-of-combustion control means 27, which controls the quantity of combustion with the deviation of the room temperature from the set room temperature, and a heater control means 31, which controls the ON/OFF of a heating heater 2, controls the heating heater 2 on the higher-temperature side than the strong combustion side. Hereby, the lift combustion can be surely prevented, by keeping the temperature of a carburetor dropping sharply with shortage of heat back at a specified high temperature.
Patent JP-S57141098-A (JP)
Title: Semiconductor device
Inventor: FUKAZAWA NOBUO
IPC: G11C16/04
Filed: 1981-02-25
Abstract: PURPOSE:To erase erroneously written information to rewrite information, by forming a programmable logic array with a readout-only storage device where the write and the erase are feasible plural times. CONSTITUTION:Electrons are charged to transistors TRs surrounded with circles of solid lines to make their threshold voltages higher, and electrons are not charged to TRs surrounded with circles of broken lines. TRs to which electrons are charged are not conductive when the voltage of an input terminal becomes a used power source voltage or below, and TRs to which electrons are not charged become conductive when it becomes higher than a threshold voltage VTH. Therefore, an output terminal 15 is set to the earth level when the potential of one of input terminals 13 and 14 is higher than the voltage VTH. That is, the terminal 15 becomes NOR between positive logics of terminals 13 and 14. Thus, information can be written plural times to a ROM of a programmable logic. Consequently, erroneous information is erased to rewrite information.

Title: Method and apparatus for recording/reproducing digital signal
Inventor: HARA MASAAKI
IPC: G11B20/18
Filed: 1994-02-24
Abstract: PURPOSE:To increase a reliability of a recording system circuit and a reproducing system circuit and improve a compatibility. CONSTITUTION:Digital reproduced signal data which is read out, reproduced and converted at a reproducing time of signals is identified at an identifier 9, and the identified result is sent to arm equalization error-calculating circuit 10. The equalization error calculating circuit 10 calculates an equalization error from the reproduced signal data and identified result. The equalization errors for a predetermined time are added at a square sum-calculating circuit 11 and sent to a system controller 5 as an evaluation value. A parameter for adjusting a recording system and a parameter for adjusting a reproducing system which are to be supplied to a recording system circuit 3 and a reproducing system circuit 7 are respectively changed a minute amount based on the evaluation value, and further changed in a direction to decrease a square sum of the equalization errors.

Abstract: PURPOSE:To reduce the sizes and improve the efficiency of a motor by composing air chambers of partition walls and partition bodies capable of passing through each other with the rotation of a rotor. CONSTITUTION:Air is introduced from an air supply port 60 to airtight chambers 31, 41, which are formed with a fixed cylinder 5, a fixed shaft 7, partition walls 70, 71 and partition bodies 51, 52. Then partition bodies 51, 52 are then pressed to rotate a rotor 6.

Similarly, ends of the partition bodies 51 to 54 are respectively engaged with the rotor 6, while the other ends are in slidable contact to the fixed cylinder 5 and the fixed shaft 7, and tiltable in the direction of the rotor 6. The partition walls 70, 71 and the partition bodies 51 to 54 are allowed to pass through each other accordingly, and they repeatedly form the airtight chambers 31, 41 caused by the rotation of the rotor 6. The sizes and weight of a motor are therefore reduced easily compared to the case of a vane type one, and the efficiency is improved better than that of a turbine type one.

Title: Semiconductor integrated circuit device
Inventor: SUZAKI SATOSHI
IPC: H01L25/18
Filed: 1990-02-07
Abstract: PURPOSE:To enhance the mounting density of a device and to make the function of the device high and the capacity of the device large in a short time by a method wherein a subchip is bonded facedown onto a base chip, both are connected and, in addition, a subchip having a separate circuit function is connected. CONSTITUTION:A subchip 1 is bonded facedown onto a base chip 3; both are connected electrically; an LSI having a prescribed function is constituted of both of them. Consequently, since an integrated circuit area can be expanded effectively without making the plane size of a package main body 2 large, a mounting density can be made higher than that in conventional cases. When a subchip 4 having a separate circuit function is connected to the base chip 3 having a prescribed circuit function, a circuit formed on the chip can be expanded and changed easily. Consequently, it is not required to sharply change the design of a device. The function of the device can be made high and the capacity of the device can be made large in a short time. In addition, since an LSI of a different type can be mounted inside the main body 2 having the same specifications, the universality of a package can be enhanced.
