Title: Semiconductor laser pulse generator and manufacture thereof
Inventor: OGAWA HIROSHI
IPC: H01S5/00
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To shorten the duration of a laser pulse by forming a saturable absorption region which are formed continuously with a gain region and defines the resonance length together with the gain region and changing the band gap wavelength in at least one active region out of a first and a second active region along the resonator length direction. SOLUTION: A gain characteristic in a gain region 25 as shown by a characteristic curve 28 is a superposition of characteristic curves (28a-28d) of respective regions and the half-value width of the characteristic curve 28 in the gain region 25 is more largely expanded than that in the first active layer of a single band gap wavelength. Since a saturable absorption characteristic in a saturable absorption region 26 as shown by a characteristic curve 29 is a superposition of characteristic curves (29a-29d) in respective regions, the half-value width of a saturable characteristic section of the characteristic curve 29 due to absorption of excitons is more largely expanded than that in the second active layer of a single band gap wavelength.  Due to the expansion of the halfvalue width of the characteristic curves, a laser oscillation spectrum frequency range can be expanded and thereby the duration of a laser pulse can be shortened.

Title: Material holding device for press die for drawing
Inventor: UJIHARA ARATA
IPC: B21D24/04
Filed: 1981-04-01
Abstract: PURPOSE:To obtain a material holding device that holds the end of a material surely without damaging it and facilitates drawing by connecting the material holding part to a wedge-shaped part of a slidable block and providing a stopping part that stops sliding of the block. CONSTITUTION:A material W to be worked is held between blocks 18, 28 that contact with stoppers 25, 35 of an upper die 10 and a lower die 37 respectively. When an inner ram 13 is lowered and a punch 14 pulls the material in the direction of a die 12, tensile force acts on the end of the material. The two blocks, 18, 28, while holding the material W, slide slanting faces 22, 32 to inside of the die until they come into contact with slanting faces 23, 34 of plates 17, 27 guided by slide planes 24, 33 of guide plates 17, 27 corresponding to slide planes 19, 29. Under this condition, the material W is drawn in the direction of the die 12. At this time, since wedge action operates between the slanting faces 22, 32 and corresponding slanting faces 23, 34, large holding force is applied to the material W, and the end of the material W is made to a nearly fixed state. Thus, it can be stretched by the punch 14 that continues to descend further.

Title: Digital data signal converting circuit
Inventor: CHIBANA MASANOBU
IPC: G10H7/00
Filed: 1978-04-24
Abstract: PURPOSE: To smoothen the variation in digital signals by interpolating input signals with the use of the up- and down-counters which are operative to generate the counted values having more bits than that of the input signals.  
     CONSTITUTION: The input digital signals of five bits or the like are compared by a comparator 1 with the upper five bits more than the input signals of ten bits, which are generated by such an up-down counter 3 as is operative to count the high frequency output from an oscillator 5. In accordance with the comparison, the comparator 1 controls the counter 3 to the down-up counting operations to interpolate the input signals. If the comparison reveals coincidence, the comparator 1 stops the counter 3. By the output of the counter 3 at this time, the five bit signals are interpolated into the converted ten bit signals so that variation in the digital signals is smoothened by the increase in the bit number. As a result, if the musical signals are generated by the system thus disclosed, accurate signals can be generated with the use of a simple construction.

Abstract: PURPOSE:To efficiently operate the demagnetization of a cathode ray tube by successively allowing decreasing alternating currents or similar currents to run through plural gausing coils. CONSTITUTION:At the time of demagnetizing a cathode ray tube 1, the decreasing alternating currents are allowed to run through a degausing coil 2 by a driving circuit 5 constituted of an alternating current power source 9 which supplies a constant voltage and a positive characteristic thermister 11 by turning ON a switch 7. After the completion of a demagnetizing operation, the decreasing alternating currents are allowed to run through a degausing coil 3 by a driving circuit 6 constituted of an alternating current power source 10 which supplies the constant voltage and a positive characteristic thermister 12 by turning OFF the switch 7 and turning ON a switch 8. After the completion of the demagnetizing operation, the switch 8 is turned OFF. Thus, the entire cathode ray tube 1 can be demagnetized by preventing a demagnetization field from being weakened due to the mutual denial of the magnetic fields of the adjacent demagnetizing coils 2 and 3.

Title: Multiple access speed demodulator
Inventor: SERIZAWA MUTSUMI
IPC: H04L27/22
Filed: 1987-03-04
Abstract: PURPOSE:To attain the establishment of synchronization in a short time even at the change in the transmission speed by revising the quantity being the result of normalizing a value stored in a tentative storage in a synchronizing detection loop, that is, the frequency offset in the synchronizing loop by means of a sampling clock at a multiple of 1/2 in multiplying a sampling clock frequency by a multiple of (a). CONSTITUTION:When a ground station B receives a multiple access speed digital signal sent from a ground station A, the station A sends a signal in any of transmission speeds, e.g., f1, af1, a<2>f1.... Moreover, the station B converts down a transmission signal into a base band complex number signal (two orthogonal signals), samples the signal by using a frequency twice the transmission speed to apply synchronizing detection. In changing the transmission speed to, e.g., a multiple of (a), the stored value of a loop filter register of a demodulator is controlled to be made to a multiple of 1/a. The control is applied similarly by varying the transmission speed and the channel. That is, since the value stored in the loop filter register is almost due to an up-converter, a down- converter and a frequency converter on a satellite, even when the channel is revised, almost no fluctuation is given to the frequency error.
