Title: Blurring correcting device
Inventor: HIRANO SHINICHI
IPC: G03B17/00
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To safely and definitely determine the beginning timing of blurring correction or assigned position control, with a simple constitution, by restraining oscillation drive corresponding to an optical system or an image pickup surface, on deciding that lock releasing is not completed, when the operation of blurring correction is started. SOLUTION: When a release button 11 is fully pushed, a blurring correcting control microcomputer 22 starts to energize a fixed magnet 29. Next, the blurring correcting control microcomputer 22 is allowed to slightly drive an X encoder 31. Subsequently, a moving amount of the blurring correcting optical system is detected, through the X encoder 32. In the meantime, if the correcting optical system is moved by drive of the X motor 31, the correcting optical system is judged that it is in a lock released state. While, if the correcting optical system is not moved, the correcting optical system is judged that it is in the locked state, and the execution of blurring correcting is tentatively restrained. In this state finding of the locked state is repeated, by executing such as a focusing control again.  On the other hand, when it is judged that the lock is released state, the blurring correcting control microcomputer 22 is allowed to execute the blurring correction.

Inventor: INOUE MICHIYA
IPC: G05B19/05
Filed: 1988-09-21
Abstract: PURPOSE:To improve the economical properties of a signal input module by in corporating an input load circuit which outputs an input signal after limiting its voltage to a prescribed level and an input conversion circuit having another function into the independent units that can be separated from each other and therefore changing only the input load circuit unit even when the type of the input signal is changed.

Title: Manufacture of cylinder head for engine
Inventor: ADACHI SHUHEI
IPC: F01L3/04
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To provide an excellent joint state by setting an annular valve seat body to a valve seated surface, heating to bring them into contact while applying a current, and changing current density in such a way as to be larger on the exhaust port side than the intake port side. SOLUTION: A valve seat is so formed that a valve seated surface 40 has an annular protrusion 46 formed by two faces that are a plane 41 and an inner tapered face 42. Valve seat body 20 is formed in an inclined state so that the peripheral surface 50 is gradually reduced in other diameter toward the cylinder head body 11 side and that the bottom face 51 is gradually shifted onto the cylinder head body 11 side toward an axis. At the time of setting the valve seat body 20 to the valve seated surface 40 and heating to bring them into pressure contact while applying a current, current density during current application is changed so as to be larger on the exhaust port side than the intake port side. An excellent joint state can thereby be obtained.

Title: Channel control system
Inventor: NORO TERUO
IPC: G06F13/12
Filed: 1988-09-21
Abstract: PURPOSE:To improve the transmission efficiency by securing the connection between the channel of an information processor and an input/output device via a loop-shaped serial transmission line and transmitting a frame including an interface action turned into a code together with the variable frame width. CONSTITUTION:A frame is sent unidirectionally to a serial transmission line 16 from a channel device 15 of a CPU 1. The frame includes the actions of interfaces 18-22 of the input/output devices 17-21 turned into the codes for each function. Each input/output device applies a data writing action to the frame as necessary and sends it back to the line 16. Then the frame returns to the device 15 in a loop via each input/output device. The data transfer efficiency is improved since the transmitting direction is fixed. When the input/output devices are scattered, the simultaneous actions of these devices are attained with a single frame. Then the total transmission time of a series of frames is approximated to the time required for one round of the loop. Thus a frame under transmission always exists on the line 16 and therefore the frames are processed at a high speed with no idle time.

Abstract: PROBLEM TO BE SOLVED: To facilitate the signal processing for the acoustic signal processing unit in which an acoustic signal with high resolution and high quality is decoded even when a dither is inserted to a frequency band higher than an audible frequency band through high frequency sampling and noise shaping. SOLUTION: Code information of an N-bit digital acoustic signal obtained by A/D-converting to a sequential sampling value resulting from sampling an acoustic signal with a sampling signal having a sampling frequency in excess of twice an upper limit frequency of an audible frequency band is divided into N-bit code information for an audible frequency band and into N-bit code information for a frequency band higher than the audible frequency band by band split filters 60, 61. After applying decimation 64 is applied to the N-bit code information for the audible frequency band, the result is given to a bit number conversion section BNC, in which the result is converted into M-bit code information in the relation of M>N.  The M-bit code information outputted from the bit number conversion section BNC is up-sampled (65) and the result and the N-bit code information outputted from the band split filter 61 are added by an adder section 63 while the most significant digits of them are in matching with each other.

Filed: 1989-09-13
Abstract: PURPOSE:To quickly learn the pattern classification by using reference vector preliminarily learnt in a self-organizing neural circuit type device as learning data at the time of learning the pattern classification by a multilayered perception type neural circuit model device. CONSTITUTION:M-number of reference vectors stored in a memory 4 are learnt in a self-organizing neural circuit type device 3 based on relations between an input pattern and the category to which the input pattern belongs to, and learnt reference vectors are used to learn reference vectors and categories, to which they belong, in a multilayered perception type neural circuit model device 6. At the time of pattern classification, the category to which the input pattern belongs is calculated by the multilayered perception type neural circuit model device 6. Thus, the number of patterns learns in the multilayered perception type neural circuit model device 6 is reduced to increase the learning speed. Since only the multilayered perceptron type neural circuit model device is operated at the time of operation, the calculation volume for pattern classification is reduced.

IPC: G01F23/28
Filed: 1987-09-22
Abstract: PURPOSE:To prevent erroneous detection due to the lowering in the output of a receiver when the surface of a liquid is at a predetermined level, by sweeping a definite range without fixing frequency singly. CONSTITUTION:A triangular wave oscillator 10 oscillates an output signal having a saw-tooth wave and the output thereof is given to the control input of a voltage control oscillator (VCO) 12 to sweep oscillation frequency. For example, the VCO 12 oscillates while sweeps a range of 100kHz-1MHz and the output thereof is emitted as an ultrasonic wave from a transmitter 16 and, as a result, a direct wave D and a reflected wave R propagate through the liquid 20 in a pipe to be received by a receiver 24. This ultrasonic wave is converted to an electric signal which is, in turn, inputted to an integrator 28 through a band- pass filter 26 to be detected as the total energy of the receiving signal during one sweeping period. Continuously, said signal is inputted to a comparator 30 and, when said signal is judged to be larger than a threshold value Vt, the comparator 30 outputs an H-level signal to give the same to an alarm 32. Therefore, the alarm 32 displays or informs that the height of the surface of a liquid is a predetermined value or more.
