Title: Processing circuit of television signal
Inventor: NAKAGAWA MASAKI
IPC: H04N9/77
Filed: 1984-02-17
Abstract: PURPOSE:To obtain a horizontal profile correction signal with respect to a high frequency band of a luminance signal by means of an adder and a filter of a coefficient multiplier and to enable the signal applicable to respective signals PAL and NTSC by utilizing a video signal at each input side of two 1H (H: one horizontal period) delay circuits and that at the output side of the other 1H delay circuit. CONSTITUTION:Video signals at I/O terminal sides of an 1H delay circuit 13a and that at the output terminal side of an 1H delay circuit 13b are assumed to be D1, D2 and D3, respectively. An adder 14 adds digitally the video signal D1 to the video signal D3, and its added output is inputted to one input terminal of an adder 16 and that of a multiplexer 18 after it passes through a coefficient adder 15. When a system is in a PAL mode, an output of the coefficient adder 15 is selected by the multiplexer 18 and outputted as a horizontal profile correction signal CSO through a band-pass filter 19. Here said signal CSO turns out a signal that having a relatively high frequency band component of a luminance signal where a chrominance signal is not mixed.

Title: Production of p-ethylphenol
Inventor: TACHIBANA YAKUDOU
IPC: C07C37/16
Filed: 1983-02-21
Abstract: PURPOSE:To improve the yield of the titled compound in the alkylation reaction of phenol and ethanol, at a relatively low temperature with simple procedure, by using a catalyst comprising a heteropolyacid supported on a carrier such as silica. CONSTITUTION:The objective compound is prepared by reacting phenol with ethanol at 150-300 deg.C in the presence of an acid catalyst obtained by supporting a heteropolyacid or its salt to a carrier selected from silica, alumina and activated carbon. The feeding ratio of phenol to ethanol is preferably 1-2.5mol of phenol per 1mol of ethanol, and the rate of feeding of the raw materials is 0.05-30hr<-1>, preferably 0.1-10hr<-1> in terms of liquid space velocity. The catalyst can be prepared by dissolving the heteropolyacid in a solvent, adding the carrier to the solution, stirring the mixture at a temperature between normal temperature and the boiling point of the solvent, evaporating the solvent to dryness, and if necessary, calcining the residue.

Title: Error detector
Inventor: MORIYAMA TADASHI
IPC: G08B21/00
Filed: 1991-02-22
Abstract: PURPOSE:To prevent a problem that the hardware of the detector in a conventional error detector is increased at an increasing tempo when an input signal line number is increased because combinations of a multi-input OR and an AND gates are employed in the input of input signal lines for the discrimination as to whether or not two error signals '1' or over are in existence among plural signal lines. CONSTITUTION:The detector consists of a multiplexer section to multiplex an input signal line and a count discrimination section 2 converting and discriminating a multiplex signal. Moreover, the multiplex section 1 is provided with a multiplexing pulse generating counter 3 used to sample the input signal. Since the combination discrimination having been required for a conventional detector is not required for the circuit discriminating count after multiplexing of the input signal lines, rapid increase in the hardware is not caused even when number of signal lines is increased.

Title: Flow rate detector
Inventor: GONDA TADAO
IPC: G01F3/10
Filed: 1986-02-12
Abstract: PURPOSE:To prevent vibrations or the like of an engine, by computing a flow rate using an average cycle of a flow rate signal when noncircular gears of a flowmeter is rotated forward and backward repeatedly. CONSTITUTION:When a power of a power source is supplied to a control unit 24, a control program starts and a projector section 26 ready to emit light. Then, a fuel is sucked into a pump rotating noncircular gears 14 and 15 of a flowmeter 5. When an optical signal is provided to a light receiving section 25 through optical fibers 22 (22a and 22b) and 23 (23a and 23b), the light receiving section 25 outputs a flow rate signal with the cycle varying depending on the rotation all speed under the forward rotation of the gears 14 and 15 while an reversion signal under the backward rotation thereof. Under the forward rotation of these gears 14 and 15, the cycle of the flow rate signal is computed and in all, four cycles including three obtained in the previous computations are memorized. When the fuel generates a pulsation, causing a forward and backward rotation in the gears 14 and 15 repeatedly, a CPU34 is given a backward rotation signal from the light receiving section 25 at the backward rotation and read out four cycles memorized to determine the average cycle. Based on the average cycle thus obtained, a control processing of the injection is done to suppress variation in the errors from the target injection value.

Title: Method for detecting residual shell in shucked shellfish and apparatus therefor
Inventor: HAYATA FUMITAKA
IPC: A22C29/02
Filed: 1988-02-09
Abstract: PURPOSE:To contrive automatic discrimination between pieces of shells and shucked shellfishes, by measuring intensity and wave form of an absorption part and absorption width of an absorption signal in an X-ray image and discriminating the X-ray absorption parts due to the pieces of the shell and shucked shellfishes based on the measured values. CONSTITUTION:X-rays are irradiated to shucked shellfishes 14 in the respective buckets 24 on a bucket conveyor 18 in an X-ray irradiator 32. An X-ray image of the shucked shellfishes 14 is received by an X-fluorescent plate 36 emitting light by sensitizing to the X-rays of a receptor having the fluorescent plate 36. Further, the light emitted from the fluorescent plate 36 is converted into an electric signal by a photoelectric transfer element 38. The electric signal of the photoelectric transfer element 38 is amplified to a prescribed level in a signal processor 40 and then subjected to logarithmic conversion to measure the intensity, width and absorption wave form of an X-ray image absorption part of the above-mentioned transferred image signal. Thereby, X-ray image absorption parts of the shucked shellfishes and pieces of shells are discriminated based on the afore-mentioned measured values. Furthermore, a control signal is taken from the processor 40 in a selector 59 to operate the bucket 24 and remove the shucked shellfishes containing pieces of shells.
