Title: Manufacture of thermal heads
Inventor: ARAI MICHIO
IPC: B41J2/335
Filed: 1986-09-30
Abstract: PURPOSE:To form an SiO2 film and a boron-doped polysilicon film thermal element efficiently on the surface of an enameled substrate using the same device by repeating the formation of a non-doped polysilicon film on the surface of an enamelled substrate and oxidation of the film prearranged times to form an SiO2 film, and further forming a doped polysilicon thermal resistor like boron-doped polysilicon on the SiO2 film. CONSTITUTION:An SiO2 film has at least approx. 500Angstrom thickness, and also is given a required performance as a barrier and an effective growth capability of doped polysilicon. Therefore, a non-doped polysilicon film of less than 250Angstrom  is formed using a gas source such as SiH4 at substrate temperature of 650 deg.C under low pressure. Next if SiH4 supply is suspended and O2 is injected for oxidation, an SiO2 film grows. If this process is repeated, an SiO2 film of more than 500Angstrom  can easily be formed. Next, O2 supply is suspended, and SiH4 and B2H6 are introduced to provide a growth of boron doped polysilicon film. Consequently the formation of an SiO2 film and a doped polysilicon film on an enamelled substrate can be achieved quickly using the same device.

Title: Detector for erroneous operation of decoder
Inventor: SEKI YUJI
IPC: H03M7/00
Filed: 1986-09-30
Abstract: PURPOSE:To simplify the constitution and to contrive to improve the performance of the titled detector to detect an operational error of a decoder by comparing an N-bit code information that is an input to the decoder and an N-bit code information that is an output of an encoder, and outputting an error detection signal when prescribed agreement is not obtained from the comparison. CONSTITUTION:The output of the decoder is inputted to the encoder circuit 2 of the error detection circuit 4, and the decoder circuit 2 executes the opposite action of that of the decoder circuit 1. Accordingly, as far as the chip actions of the circuits 1 and 2 are normal, the 3-bit code information output of the circuit 2 is identical to the 3-bit code information input of the circuit 1. A data comparison circuit 3 compares these 3-bit code information input and 3-bit code information output, and outputs an error signal to its output terminal 0 in case of disagreement is obtained. In such a way, the titled detector can be constituted with less circuit elements, and can be made effectively detect many kinds of operational errors.

Title: Method for measuring compaction extent of compacting member
Inventor: HASHIMOTO TSUKASA
IPC: G01N22/00
Filed: 1988-09-16
Abstract: PURPOSE:To measure the compaction extent without any destruction and to grasp its variance by calculating the amount of water from the voltage or propagation time of an electromagnetic wave propagated in the surface layer part of the compacting member and finding the density. CONSTITUTION:A transmitter 1 and a receiver 2 are installed on the compacting member (e.g. heaped-up material) (m) and the pulsating electromagnetic wave is sent into the member (m) by the transmitter 1. Then the surface propagated wave which is propagated in the surface layer part of the member (m) is received by the receiver 2 and displayed on a display device 4 through a control part 3. The surface propagated wave is received while attenuated or delayed in propagation time in proportion to the amount of water in the heaped-up material, so the amount of water is calculated from a prepared relational diagram of water content and arrival time to decide the density.

Abstract: PURPOSE:To enable the enhancement of mixing effect in a reactor even if a packing material with a small particle size is used, by enhancing mixing effect by introducing air bubbles into the reactor while removing air bubbles resulting in the obstruction of detection in the post stage of the reactor. CONSTITUTION:In such a state that a carrier is flowed to a flowline 7 from a carrier supply part 1, the specimen injected in a specimen injection part 2 reaches a separation column 3 to be separated into components and a reagent from a reactive reagent injection part 4 is mixed in the separated components.

The fluid mixture from the reactor 5 reaches a detector 6 but, during the passage of the mixture in the Teflon pipe 10 of an air removing apparatus 9 on the way of the flowline from said reactor 5, air bubbles present in the mixture are removed. That is, the internal air in the mixture is sucked from an air vent part 12 and only the liquid remains. As a result, accurate detection can be performed by the detector 6.

Abstract: PURPOSE:To decide on a center frequency on a center meter all the time by adding the detection output of the S curve of an intermediate frequency signal to the opposite-phase detection output of an opposite-phase S curve, and comparing the addition output with the detection output. CONSTITUTION:The signal generated by shifting the phase of an IF signal from an intermediate frequency amplifier 1 through a phase shifter 6 and the original IF signal are inputted to a detector 8 and an opposite-phase detector 10 and multiplied by each other to obtain the detection output signal S1 of S curve characteristics and the detection output signal S2 of opposite-phase S curve characteristics. The signals S1 and S2 are summed by an adder 12 to obtain the output level DELTA(-V) at the intersection A of the signals S1 and S2. The output of the adder 12 is compared by a comparator 14 with the output of the detector 8 to output the voltage level of S curve characteristics S1 which has a DC zero point at the intersection A of the signals S1 and S2 corresponding to the difference between the both from a terminal 14a. Then, the frequency where the deflection of the center meter is zero is calculated to decide that the voltage level is a center frequency.
