Title: Magnetic head and its manufacture
Inventor: SAKAI KUNIHIDE
IPC: G11B5/127
Filed: 1982-04-19
Abstract: PURPOSE:To obtain a magnetic head adaptive to a magnetic recording medium which has high coercive force by forming magnetic films with large saturated magnetic flux density over the nearly entire butting surfaces of core falf bodies and butt-jointing them. CONSTITUTION:A magnetic alloy material, such as ''Sendust'' alloy, which has a coefficient of thermal expansion nearly equal to those of rectangular parallelepiped blocks 1 and 2 of ferrite blank materials and greater saturated magnetic flux density than those blank materials is sputtered over the butting surfaces of the rectangular parallelepiped blocks 1 and 2 to form ''Sendust'' alloy films 6 and 7. Then, a nonmagnetic material, e.g. quartz glass which has a relatively high softening point is sputtered to form a thin film 10 over the ''Sendust'' alloy film 7 of the front gap constitution side to gap width (g), and a nonmagnetic material, e.g. glass which has a relatively low softening point and a coefficient of thermal expansion nearly equal to that of the ''Sendust'' alloy film 7 is sputtered over the ''Sendust'' alloy film 7 of the rear gap constitution side to form a thin film 11; and grooves and holes formed in those blocks 1 and 2 are charged with fused glass to constitute a block 14.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To sufficiently spread underwater sludge without making water muddy, and efficiently suck the underwater sludge through a suction hose. SOLUTION: A dredging device of underwater sludge sedimented on the bottom of reservoir, river or the like sucks underwater sludge together with water by means of a conveying machine 1, and the sludge and water to be sucked are moved to a treatment machine 2 to separate sludge from water by the treatment machine 2.

The dredging device connects a blocking cylinder 6 to the suction end of the conveying machine 1. The blocking cylinder 6 formed in the shape of a cylinder has a downward opening and a closed circumference. A nozzle 10 for spreading the sludge inside of the blocking cylinder 6 by injecting high pressure water is provided to the inside of the blocking cylinder 6.

Title: Vibration type force detector
Inventor: KAWAMOTO AKIRA
IPC: G01L1/10
Filed: 1984-03-31
Abstract: PURPOSE:To make it possible to select a vibrating body having effective mechamical characteristics without limitation on the quality of the vibrating body, by offsetting the potential, which is generated by the product of the electric resistance of the vibrating body and an exciting current, by a potential obtained by dividing the exciting voltage. CONSTITUTION:A vibrating chord 2 is arranged in a magnetic filed 1. The electromotive force generated by the vibration of the vibrating chord 2 is amplified by an amplifier 3 and fed back to the vibrating chord 2 through a resistor 4. The exciting current flows through two circuits of the vibrating chord 2 and a resistor 5 and resistors 6 and 6. The amplifier acts as a differential amplifier, which amplifies the potential difference voltage between the connecting point of the vibrating chord 2 and the resistor 5 and the connecting point of the resistor 6 and the resistor 7. Thus the potential, which is not related to the electromotive force generated by the vibration of the vibrating chord 2, is offset.

Title: Photometry controller of automatic focusing camera
Inventor: KAWAMURA MASAHARU
IPC: G03B7/08
Filed: 1984-03-30
Abstract: PURPOSE:To seize securely a shutter chance by meter light during a storage time when subject brightness is low and performing storing operation and light metering operation in time series when the subject brightness is high and the storage time is short. CONSTITUTION:Outputs of output ports T0-T3 of a CPU are K-Tv corresponding to an APEX value of shutter second time, so a decimal decoder DE1 selects one output among binary inputs. A counter CN1 is released from being reset and counts clock pulses from a clock generator CG1. A digital comparator MC1 compares the output of a decoder DE1 with the output of the counter CN1 and outputs a signal HL to a terminal R of an FF1 when the outputs coincide with each other. Consequently, the time from the turn-on point of a counter switch SW4 to the resetting point of the FF1 is raised to the (K-Tv)th power, i.e. equalized to the shutter second time. Consequently, a shutter chance is seized securely even by a camera with an automatic focusing function.

Abstract: PURPOSE: To enable to write in the data and check bit being uncorrectable error to memory units after simple production, by compulsively inverting at least 2 bits of check bits.  
     CONSTITUTION: A memory controller 6 includes a check bit production circuit 11 and inversion elements 12, 13. At least, two bits are inverted (by elements 12, 13) with a parity error signal 15 to a plurality of check bits produced from the circuit 11 from write-in data 14 to form the write-in data being uncorrectable error. Thus, by the write-in data and check bits formed, when the parity error signal is detected in the data from CPU1, the error of two bits or more is formed compulsively as uncorrectable error and this is written in the memory 7. Accordingly, in checking the data read out from the memory 7 and the check bits, if the said uncorrectable error is taken place, it can be detected as two-bit error.
