The heating penetration depth in this case is set at about the same degree as the depth of the thermal influence of laser light 12a (i.e., degree of the wall thickness). The quantity of heat for preheating is set at the extent at which melting of metal arises hardly. The material 1 after preheating is conveyed in a direction A while the contact state of a joint part 1a is maintained by squeeze rolls 11a, 11b until the joint part 1a arrives right under the laser light 12a, where the joint part is melted. Since the joint part 1a is preheated, the laser power of small capacity is required and a considerable reduction in cost is attained.

Title: Illuminator
Inventor: OTSUKI SHINICHIRO
IPC: H04N1/04
Filed: 1986-07-02
Abstract: PURPOSE:To obtain an illuminator which is easily controlled, and by which illuminance distribution can be easily corrected, by reducing the number of constituents in a light emitter group at the most outside part fewer than that in the center part. CONSTITUTION:Several groups of micro light emitters 1 are arranged on a substrate 4 keeping equal pitches in a line shape. And three pieces of the micro light emitters in groups 14a-14e are arranged, for example, at a right and a left end parts 14a and 14e, respectively, and four pieces of them, in the center parts 14b-14d, respectively, and each group is arranged in parallel, and is connected in series to a current limiting resistance 2, and a driving circuit 3, respectively, and a control signal is taken out from each driving circuit 3. Since a voltage impressed on each group is equal, the voltage impressed on each light emitter 1 is increased inversely proportionately to the number of pieces. As for the light emitter 1, the higher the voltage, the larger is the light quantity, in general, therefore, the light quantity in each light emitter in the groups of 14a and 14e at a peripheral part is increased compared with that of the groups of 14b-14d in the center part. So that the light emitters 1 are arranged with the equal pitch, the illuminance at the peripheral part can be corrected as shown in broken line 15b.

IPC: H01L21/331
Filed: 1979-11-30
Abstract: PURPOSE:To improve the characteristics of a power semiconductor device by a method wherein a P is selectively diffused on the surface of an Si substrate having a P-N juntion. CONSTITUTION:The lifetime of the semiconductor device is prolonged by the gettering effect when the P, B and the like are diffused in the Si substrate. In the case of a diode, an SCR and the like, an Au is diffused for the pourpose of reducing an arc extinguishing time. at this time, the diffusion coefficient of the Au contained in the Si substrate varies greatly due to the contents of the impurities in the Si substrate, especially with the N type impurities such as the P, an As and the like. When an N<+> layer 33 and a P layer 32 are superposed on both sides of an N type Si substrate 31, an SiO2 mask 34' is provided on the N<+> layer 33 and the Au is evaporated and diffused, a region having a different lifetime is formed on the flat direction of the Si substrate on the semiconductor device, thereby enabling to obtain a low ion voltage at the high lifetime region and to reduce a switching loss on the low lifetime region.

Abstract: PURPOSE:To improve the printing quality and production yield along with a longer life of the heat generating resistor by alternately laminating a dielectric member and a resistance member to form a heat generating resistor of a thermal head. CONSTITUTION:Aluminum nitride (AlN)4 as dielectric member and tantalum nitride (Ta2N)5 as resistance member on a substrate 3 in 24 layers in the order of Ta2N, AlN, Ta2N, AlN...to form a heat generating resistor. The film thickness of the heat generating resistor 5 thus formed is preferably 2,000Angstrom , that of aluminum nitride 6-10Angstrom  and that of tantalum nitride 10-15Angstrom . In the case, 1- 30Angstrom  is enough for the thickness of aluminum nitride. The specific resistance of the resistor thus formed is 20,000muOMEGAcm and proves sufficiently usable in practice. This makes the product short in the shape and eliminates the need for a less film thickness thereby extending the life of the resistor.

Inventor: NAGAOKA SHINJI
IPC: E02B8/02
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To stably scour sediment with an inexpensive and simple structure by guiding the sediment from the upstream into a scouring pipe via multiple opening sections provided at least in the prescribed upstream side position of a water storage region formed by a damming means, and flowing and scouring the sediment to the downstream side of the damming means together with flowing water. SOLUTION: The sediment flowing down together with flowing water is guided into a scouring pipe 4 via upstream opening sections 8 directly or after being dammed by oneend damming members 5. The flowing water and sediment flow down together in the scouring pipe 4 to the downstream side of a dam 1. The sediment is scoured to the downstream side of the dam 1 in sequence without being accumulated in a water storage region 2, and no scouring work is required. A proper quantity of sediment corresponding to the flowing water quantity flows down, thus such a problem as the erosion of a riverbank caused by the decrease of the flowing-down sediment quantity does not occur. This device can be installed on a river, and matters giving a harmful influence in progressing the work such as land purchase are reduced.

Filed: 1989-06-19
Abstract: PURPOSE:To obtain a control clock or a frequency dividing clock with high phase accuracy in a PLL circuit by amplifying an oscillation signal from a voltage control oscillator by a driver, and feeding back the amplified signal to phase comparator. CONSTITUTION:When an input signal fS passes a gate 11 if N of a 1/N frequency divider is assumed as '2', the frequency of the signal fS is divided into 1/2 and a reference signal f0 is outputted. When a signal (y) obtained by similarly dividing the frequency of an oscillation signal fVCO from a VCO 15 into 1/2 passes a gate 16, an output signal fout is outputted. Respective duty ratios of the reference signal f0 and the output signal fout are halves of the duty ratios of respective signals fS, fVCO. The signal fout amplified by a driver DR 17 can be used for driving a large load capacitor 18 such as a control clock and synchronized with the phase of the signal fS. The phase of the gate passing signal f1 of the signal fout is directly compared with that of the gate passing signal f0 of the signal fS by a comparator PC 12. Thereby, when the characteristics of gates 11, 13 coincide with each other, the phases of the signals fout, fS can be accurately matched with each other.
