Patent JP-S6341091-A (JP)
Title: Laser oscillator
Inventor: TAKENAKA HIROO
IPC: H01S3/10
Filed: 1986-08-06
Abstract: PURPOSE:To achieve a stable machining process by realizing the well reproducible machining conditions of a workpiece by a method wherein, when the magnitude of the output laser beam reaches a predetermined reference value, the supply of a discharge current to a flash lamp is stopped so that the magnitude of the output energy of a laser beam can be kept constant. CONSTITUTION:A part of a laser beam received by a photodetector 6 (pin- photodiode) is converted into an output voltage Vo through a photodetection circuit 10. This output voltage Vo is compared with a reference voltage Vref which corresponds to the output laser energy preset by a comparator circuit 11, and the comparator circuit 11 outputs a coincident signal as soon as the output voltage has become equal to the reference voltage Vref. The coincident signal is output, BCR2 becomes conductive, and a charging current V2 of a capacitor Co for commutation use is applied to the cathode side of SCR1. SCR1 is turned into the state of a reverse bias and is turned OFF so that the supply of the discharge current to a flash lamp 4 is interrupted to stop the laser oscillation.

IPC: A23K1/00
Filed: 1986-08-08
Abstract: PURPOSE:To chemically destroy peridermal tissues of chaff and efficiently obtain a chaff feed having improved digestibility at a low cost in a short time, by adding calcium carbonate and plural species of bacteria to ferment the chaff. CONSTITUTION:Calcium carbonate, e.g. bone meal of chicken or powder of oyster shell, and plural kinds of bacteria are added to ferment chaff and afford the aimed chaff feed.

Title: Semiconductor laser element
Inventor: KOBAYASHI UICHIROU
IPC: H01S5/10
Filed: 1981-11-20
Abstract: PURPOSE:To prevent photochemical oxidation due to the rise in temperature and thereby to prevent the deterioratin of an end surface, by a method wherein the edge part of an active layer wherefrom laser beams are emitted is made not to be oscillated. CONSTITUTION:After a substrate 1 made of n type GaAs is prepared, a groove (channel) 2 is provided by etching in the center of the main surface of the substrate 1. This groove 2 serves as a groove determining an oscillation region which is an optical cavity (optical waveguide) of a semiconductor laser. Both ends of the groove 2 are positioned inside the end surface of the substrate 1, not reaching the same, differently from conventional ones. As the result, a reflector surface whereat lasing is conducted is formed on the end surface of the groove 2 located inside the end surface of an element, an active layer 4 located between the reflector surface and the end surface is not oscillated, and thus the rise in temperature due to the concentration of current is suppressed. Accordingly, the deterioration of the end surface is hard to occur, and the stability of the quality of the element, i.e. the reliability thereof, as well as the yield, can be improved.

This signal is temporarily stored in a buffer 5, and the information of code amounts (m) is transmitted to a code amount controlling circuit 6.  The target value of code amounts to be generated for the picture of one frame is calculated by a code amount controlling circuit 6 for each frame based on a transmission rate, the code amounts (m) of the encoded data stored in the buffer 5 are always monitored, and a quantization coefficient (q) is changed so that the code amounts (m) can approach the target code amounts, and feedbacked to the picture encoder 4. Thus, the feedback control of the code amounts can be attained, and the transmission rate can be controlled.

IPC: F23D14/02
Filed: 1991-06-28
Abstract: PURPOSE:To improve the holding effect of main flames in a thick and thin fuel combustion type combustion apparatus, and to reduce the loads on burner ports and combustion noise. CONSTITUTION:A thin fuel-air mixed gas passage 2 is separated from a thick fuel-air mixed gas passage 3 by a partition wall 4. A contact edge 5 of the partition wall 4 with a burner port plate 1 is formed into a blade-like shape. Thereby, main and auxiliary flames formed on the burner port plate 1 are not separated from each other and the holding effect of main flames is improved, resulting in stabilization of main flames. Moreover, as an area on the burner port plate 1 where flames are not formed can be eliminated, the area efficiency is improved and the loads on burner ports and combustion noise are reduced.

Title: Radiation thermometer
Inventor: TAKAHASHI KENICHI
IPC: G01J5/10
Filed: 1984-09-05
Abstract: PURPOSE:To accurately measure the temp. of relatively low temp. matter, by intermittently passing infrared rays by a chopper and taking out a signal component by the demodulator synchronized with the chopper and a low pass filter. CONSTITUTION:Intermittently changing infrared rays are incident on an infrared detector 11 by the action of a chopper 9. The output of the infrared detector 1 is inputted to the demodulator 13 synchronized with the chopper 9 to demodulate a signal component. Because disturbance light applied on the way of an infrared ray transmitting fiber 10 is not modulated by the chopper 9, said light is inversely modulated by the demodulator 13 and the disturbance component is distincted and only the signal component is left. This light component is converted to temp. by a data processor 5 consisting of an amplifier and a linearizer.

Filed: 1990-07-13
Abstract: PURPOSE:To improve degrading of an image in an interest area attributed to a spatial unevenness of sensitivity of an RF coil by applying an intense magnetic field immediately after an area near the RF coil is excited selectively to cause a false saturation with the scattering of a nuclear spinning. CONSTITUTION:A frequency band of a 90 deg. pulse to be applied together with an inclined magnetic field Gy is selected to excite an area near a transmitting/ receiving coil 22 in a direction Y to an terminal Yk on the side of a transmitting/receiving coil of an interest area 42 from a position of the transmitting/receiving coil 22. Immediately after a nuclear spinning is tilted by 90 deg.. an intense pulse with inclined magnetic fields Gx, Gy and Gz is applied to cause a false unsaturation selectively. In a normal pulse sequence thereafter. no NMR signal is generated from this area. After an adjustment of a peak value of a 90 pulse. if a false saturation sequence is added ahead at each repeti tion of an imaging sequence, the nuclear spinning of the interest area 42 is always tilted by 90 deg. accurately while there is no signal generated from the area near the transmitting/receiving coil 22 thereby achieving an S/N ratio of an image of the interest area 42.

Title: Car stop
Inventor: MUROTA HIDEO
IPC: C08L101/00
Filed: 1993-06-30
Abstract: PURPOSE:To obtain a high-safety, low-cost car stop which hardly injure the person or break the vehicle at the collision of a person or a vehicle. CONSTITUTION:The car stop is provided with an elastic, columnar rubber chip molded piece 3 which is obtained by setting under pressure a mixture of rubber chips with a synthetic resin binder and a rigid core material 2 embedded in the rubber chip molded piece 3 from the intermediate part to the lower part except the upper part at approximately the center of the rubber chip molded piece 3. Since the car stop has an elasticity, even at the collision of a person or a vehicle, the car stop never injures the person or breaks the vehicle and but has a high safety. In addition, since the core material 2 made of a steel pipe is embedded in the rubber chip molded piece 3 from the intermediate part to the lower part except the upper part at approximately the center of the rubber chip molded piece 3, a bumper of a vehicle comes into contact with an elastic part in which the core material 2 is not embedded. Therefore, the shock can be reduced, and the car stop is hard to break.
