Title: Powdery dust content monitor
Inventor: YUUMIN SHIYOU
IPC: G01N5/00
Filed: 1992-04-20
Abstract: PURPOSE: To obtain a monitor for analyzing the content of powdery dust directly which can be operated easily while decreasing the frequency of maintenance and can be applied to an exhauster for high temperature powdery dust content by providing a cyclon separator, a microbalance, a radar and a pressure difference indicator. CONSTITUTION: An exhaust gas is fed from a sampling head 201 through a pipe 201a to a cyclon separator 203 where a spiral flow is produced. Powdery dust in the exhaust gas flows centrifugally toward the wall of the separator 203 and falls into a cup 2111 in a microbalance 211. Upon elapsing a predetermined time, a recorder 212 records the weight of powdery dust in the cup 211a. Since the powdery dust is separated from the exhaust gas, the content of the powdery dust can be analyzed and recorded without stopping the monitor entirely and it can be monitored continuously over a long time. Furthermore, lines 209a, 209b are protected by protrusions 213, 214 and maintenance is facilitated by eliminating clogging due to the powdery dust. Measurement of a fluid speed is also facilitated using a pressure difference indicator.

IPC: G11B5/39
Filed: 1989-05-19
Abstract: PURPOSE:To lessen the fluctuation of depth by polishing a substrate in parallel with the sides parallel with each other of shunt films to expose the shunt films and executing the polishing until the width of the parts of the shunt films exposed on the polished surface attains a prescribed length while measuring this width. CONSTITUTION:The substrate 9 is polished in parallel with the sides parallel with each other of the shunt films to expose the shunt films and the polishing is executed until the width of the parts of the shunt film exposed on the polished surface attains the prescribed length while this width is measured. Specified relations are therefore provided between the width and depth of the shunt films exposed on the polished surface and magneto-resistance effect element films 10. If, therefore, the width of the shunt films exposed on the polished surface and the MR elements films is measured, the depth of this time is known. The management of the depth is facilitated in this way and the fluctuation in the depth is lessened.

Title: Combustion detection device for internal combustion engine
Inventor: OSAWA TOSHIO
IPC: F02P17/12
Filed: 1990-05-18
Abstract: PURPOSE:To correctly detect a combustion condition in no relation to level variation of ion current and improve reliability by generating different threshold according to an operation condition of an internal combustion engine. CONSTITUTION:A ECU 10 drives a power transistor 11 based on a standard positioning signal L corresponding to the crank angle of respective cylinders. Ignition plugs 13 discharge sparks at a specified timing. Ion current I which is generated between gaps of the ignition plugs 13 is taken in an ion current detection device 20 just after the discharge. In the ECU 10, level of the ion current I is judged based on an output signal of a comparator 27. In the ECU 10, a threshold level variation circuit 30 is controlled. The threshold TH in the low level is generated, for example in a normal condition. A combustion condition is surely detected even if the level of the ion current I is varied by the operation condition.

Inventor: TAJIMA KAZUHIRO
IPC: G01N21/88
Filed: 1988-05-26
Abstract: PURPOSE:To surely detect a minute defect by forming a shape of a pattern for constituting a circuit element as a rectangle and comparing the number of picture elements derived from the product of the number of lateral and longitudinal picture elements, and the number of picture elements of the pattern which has been brought to image pickup actually. CONSTITUTION:By utilizing a fact that a pattern for constituting a circuit element is a rectangle, an inscribed rectangle is drawn in its pattern against an image which has been inputted from a camera, and that which has the largest number of picture elements therein is recognized as a resistor. Subsequently, with regard to its resistor 11, the number of picture elements A, B in the lateral direction and the longitudinal direction are measured. Next, the number of picture element C in the rectangle which has been formed on the inside of several picture elements is counted against an image which has inputted the resistor 11. Also, the product AXB of the number of picture elements A, B is derived. Thereafter, the number of picture elements AXB and the number of picture element C are compared. In this case, when there is a picture element which is not counted as the number of picture elements of the resistor 11 due to existence of a defect 12, etc., AXB>C. Accordingly, even when the number of picture element is one, a minute defect can be detected with high reliability.

Title: Fuel supply controller for internal combustion engine
Inventor: KATAOKA RIYUUJI
IPC: F02M7/24
Filed: 1977-10-21
Abstract: PURPOSE: To prevent the shock to vehicle due to the delay of fuel supply at re- acceleration and continue supplying fuel as long as the brake is not operated during the inertial driving with the clutch cut off or the transmission neutralized.  
     CONSTITUTION: In normal running, a negative pressure supply passage 10 is shut off by a valve 11 because a brake pedal 13 is not operated, and a slow fuel passage 6 is opened by a valve element 9e because the external air is introduced into a negative pressure chamber 9a of a pressure-responsible valve 9 through a leaking hole 9f. Thereby, the normal running is continued. Depressing the brake pedal 13 when a throttle valve 13 is quickly closed and the intake negative pressure in a mixture passage 2 strengthens during the decleration, a link 12 moves leftward. Then, said passage 10 is opened by the valve 11 and the intake negative pressure is supplied to the negative pressure chamber 9a of the valve 9. If the intake negative pressure is stronger than the force of a spring 9d, a diaphragm 9c moves rightward and said passage 6 is shut off by the valve element 9e.

The lowering operation is continued by looping S15-S17 during the lowering operation, and when the shutter reaches a lower limit position, a closing operation is completed and a flow is ended (S17). At the time of receiving sensing signals from an obstacle sensing part during the operation (S16), lowering is stopped (S18) and inversion and elevation are performed for prescribed time (S19). Thereafter, stoppage is performed for fixed time (S20) and the lowering operation is performed again (S15).
