Title: Delay detecting circuit
Inventor: NIINA SABUROU
IPC: H04L27/18
Filed: 1981-04-03
Abstract: PURPOSE:To compensate the demodulation distortion due to the shift of a carrier frequency, by adding a preamble word for phase detection to the start of each burst to detect the phase and holding the phase only in the duration of the burst to control a variable phase shifter. CONSTITUTION:An input phase modulation wave is inputted to one input of a phase comparator 102, and this modulation wave has the phase shifted in a circuit 104 by pi/2 and is inputted to one input of a phase comparator 102'. The input phase modulation wave is delayed in a delay circuit 101 by components of the one-bit interval, and the output is inputted to a variable phase shifter 105. The output of the phase shifter 105 is inputted the other inputs of comparators 102 and 102', and the phase difference output obtained from the comparator 102' is given to a sample holding circuit 106, and the value of the input signal of the circuit 106 is sample-held within the duration of a preamble word arranged in the start of the burst of the communication signal, and the phase shifter 105 is controlled for the burst time. The demodulation signal of the output of the comparator 102 is decoded by a decoder 103 to become a receiving output. Thus, the demodulation distortion due to the shift of the carrier frequency of each burst is compensated automatically.

Abstract: PURPOSE:To make it possible to obtain balanced stereophonic reproduced sound by providing side speakers provided in the front and left and right sides of listeners arranged in a row and reproducing left and right channel signals corresponding to stereophonic sound sources, a center speaker that reproduces both channel signals of stereophonic sound sources and a delaying device that gives a specified delay time to both channel signals inputted to the center speaker. CONSTITUTION:R channel sound is radiated from the side speaker 20(R) positioned at the front right side to a rider M1, and L and R channel sound is radiated from the first and second center speakers 22(R), 23(L). At this time, R channel sound component which is the same channel as the sound of the first side speaker 20(R), i.e., the sound of the first center speaker 22(R) acts on the ear of the rider M1 as if it were reverberation to the sound of the first side speaker 20(R). The sound of L channel of the second center speaker 23(L) is actualized and reaches dominantly the left ear of the rider. Stereophonic sensation can be obtained by the first side speaker 20(R) that radiates R channel sound and the second center speaker 23(L) that delays and radiates left channel sound.

Title: Conversation type numerical control lathe device having edged tool correction offset function
Inventor: NISHIGAKI HIROBUMI
IPC: G05B19/404
Filed: 1984-03-19
Abstract: PURPOSE:To improve the working speed of thick and thin working by switching tool offset even if the working is not returned to the original point of a program when the same working edged tool is used. CONSTITUTION:When a tool No. and an edged tool No. are changed, working for returning to the original point of the program is once tried to prevent the tool from collision with a substance to be worked, but when only an edged tool correction offset No. is changed, the working is continued without return to the original point. Since the quantity of edged tool correction and the quantity of edged tool correction offset have been incorporated into calculation at the initial stage of automatic calculation for working data to form a working shape, the edged tool is prevented from sharp insertion into the substance to be worked even if the edged tool correction offset No. is changed. Consequently, the working type and working operation may be the same as a case setting up the edged tool correction offset No.0 to set working data on the basis of the size of the shape to be worked. Even if the quantity of edged tool correction is changed, the quantity of edged tool correction offset is not changed, so that thick and thin working is not almost influenced.

Title: Medical laser apparatus
Inventor: KOSAKA YOSHIHIRO
IPC: A61N5/06
Filed: 1989-03-03
Abstract: PURPOSE:To avoid the continuation of the irradiation of a region other than a necessary range with laser beam without being aware of this irradiation state by mounting a control means discriminating the over-radiation of a living boyd part having an electrode arranged thereto with laser beam on the basis of the signal generated by a detection means to stop the oscillation operation of a laser oscillator. CONSTITUTION:When a measured current (i) is lower than a predetermined value, the electrode 11 in the body is regarded to be not sufficiently brought into contact with a living body and a current measuring device 8 sends the signal corresponding to this state to a laser oscillator 1 to perform control so that laser beam is not oscillated from the laser oscillator 1. When the current (i) is equal to or more than said value, the electrode 11 in the body is regarded to be sufficiently brought into contact with the living body to bring the laser oscillator 1 to such a state that oscillation operation is possible. The current measuring device 8 always compares the stored current value (i) with the current value i' during irradiation and, when the change quantity i'-i exceeds a predetermined value, for example, 0.1mA, a stop signal 12 is transmitted to the laser oscillator 1 to automatically stop the oscillation of laser beam. By this method, the continuous irradiation of the normal tissue of a living body other than a lesion part 6 can be prevented and safety is secured.
