Title: Synchronizing coupling system for pal synchronizing signal generator
Inventor: MIYAUCHI NAOKI
IPC: H04N9/475
Filed: 1981-04-03
Abstract: PURPOSE:To simplify the circuit constitution, by synchronizingly coupling PAL pulses through the use of PAL pulse information included in a phase comparison voltage. CONSTITUTION:An input pulse system composite video signal becomes only a burst signal at a burst separating section 1, and when a subcarrier signal (a) of an output of a voltage controlled oscillator 7 is clamped to a ground potential with a clamp pulse b shaped with this burst signal at a clamp circuit 5, since the PAL burst is phase-separated at each line, the average value of the subcarrier signal (a) of the 1st line H is lower than the ground potential and is increased at the next line. This waveform is shaped and the average value is taken and the output frequency of an oscillator 7 is changed and the subcarrier output signal (a) is synchronizingly coupled with the burst of the input signal. This control signal d initially sets the counter of a PAL pulse generating section 9, allowing to synchronizingly couple this PAL pulse output with the PAL pulse information included in the input signal.

A specific mask pattern is written in the memory 18 previously. The video signal of the 2nd object to be positioned is written in said memory 13. Data written in the memory 13 and memory 14 are read out at intervals of one or several bits according to the state of the memory 18 and supplied to TVs 3a and 3b. Both object pictures are displayed on the TVs 3a and 3b as longitudinal and lateral stripes alternately. The positioning operation is completed when the 2nd object is moved and both pictures displayed on the TV3a and 3b coincide with each other.

Title: Ultrasonic curing device used under mri guide
Inventor: AIDA SATOSHI
IPC: A61F7/00
Filed: 1993-03-10
Abstract: PURPOSE:To reduce the risk of mis-irradiation and ommission in curing and to shorten the curing time by forming an ultrasonic wave applicator by a non- magnetic substance, and transporting the applicator fixed to a bed, with a focus point set on the cured part of the patient into a MRI gantry. CONSTITUTION:An ultrasonic applicator 1 is formed by a non-magnetic substance and fixed to a bed 22, with a focus point 7 set on the cured part (e.g. tumor) 8 of a patient 3 to be transported in such a fixed state into a MRI gantry. Accordingly, the ultrasonic applicator 1 can be fixed to the diseased part 8 from the start of diagnosis and curing to the end thereof. Thus, it is possible to reduce the risk of erroneous-irradiation and ommission in curing due to a difference between the initially set position of the diseased part 8 and the position of the strong ultrasonic wave focal point 7, further eliminate the trouble of repositioning at the time of repeating diagnosis and curing, and shorten the curing time.

Title: Semiconductor light-emitting element
Inventor: MATSUOKA TAKASHI
IPC: H01S5/00
Filed: 1989-03-01
Abstract: PURPOSE:To obtain high quality crystals with minimum defects by epitaxially growing, on a substrate, crystals having lattice conformity with a substrate. CONSTITUTION:A semiconductor light-emitting element consists of a 5mum thick N-type InGaN layer 7 grown on an MgO substrate 6 and having lattice conformity with the substrate, a 0.5mum thick light-emitting layer 8 of InGaN doped with Zn to increase a resistance and having lattice conformity with the substrate, an electrode 9 on the light-emitting layer and an ohmic electrode 10 on the N-type layer 7. When a positive voltage is applied to the electrode 9 and a negative voltage is applied to the electrode 10, the light-emitting layer 8 emits light at a wavelength of 570nm. An extremely high external quantum efficiency of 0.45% can be obtained. It can be considered that this is because when crystals having a lattice constant matched with that of the substrate are grown on the substrate those crystals have higher crystallinity. Further, if the InGaN layer used in the element of the present invention is doped with aluminum under condition such that it has lattice conformity with the substrate, the element is enabled to emit light up to a ultraviolet region of about 413nm.

WSiN is compact and has low mutual reactivity as compared with W, WSi, etc., and when it is used for coating GaAs, no reaction occurs between GaAs and WSi nor surface oxidation of GaAs occurs. In addition, no reaction occurs between AuGe/Ni and WSiN.

Filed: 1989-03-03
Abstract: PURPOSE: To minimize the requisite memory capacity and reduce the circuit cost by storing the digital reference value of a hydraulic adjust current to control the adjusting pressure of an automatic transmission in a memory place with an address based on two engine parameters. CONSTITUTION: A microprocessor makes AD conversion of an accelerator pedal position signal, and the resultant value is stored in a register R6' as a load value and fed to a cumulator A to undergo a one-digit left shifting so that the lower five digits are erased. To any empty digit in the cumulator A, the engine speed is read from a counting register R1 and read into a register R4' as a lower table value. An inquiry is made for which characteristic region to be applied, and an upper table value obtained by 20H heightening the lower table value R4' in the applicable region is read into the cumulator A, and a hydraulic adjust current is set through 16 runs of interpolating calculation. Thereby the requisite memory capacity is lessened and the circuit configuration is simplified, and the adjusting pressure can be controlled accurately and finely.
