Abstract: A process and device are claimed for the cosmetic partial or complete lightening of hair colour. Hair is irradiated a lock at a time by passing through a laser beam strong enough to degrade the melamine in the hair, but not so strong that the keratin is damaged. Keratin in dark hair is degraded at a lower energy density than that in naturally light hair. Several irradiation passes are made on each lock of hair until the desired colour is achieved. The laser used has an energy density of 0.1-1.2 J/cm<2> at a wavelength of 532 nm. The energy density used varies, proportional to the wavelength.

Abstract: A circuit and related method are provided for maintaining a desired spacing between an ink-jet printing means and a receiving surface along a line scanned by the printing means. An ultrasonic transducer transmits signals at timed intervals to the receiving surface from the printing means. A reflected signal from the receiving surface is sensed by the transducer during a receiving time window after the signal is transmitted. A reference position signal representative of the head to surface spacing at a printing location is compared to the desired head to surface spacing to produce a position error signal. A servomotor responds to the position error signal to move the printing means toward and away from the receiving surface to maintain the desired spacing.

IPC: B29C65/00
Filed: 1979-09-26
Abstract: PURPOSE:To enable friction-welding of a plastic hollow object with an improved joint strength and size accuracy even if it has no stength enough to withstand a pressure-contacting, by a method wherein a pressurized fluid is poured by pressure  into the plastic hollow object, and friction- welding takes place in such a state as pressurizes the inside thereof. CONSTITUTION:A rotary shaft 2 of a friction-welding device 1 is supported by means of a bearing 3 so that it can freely move vertically, and a clamp 5 is secured on a lower end of the rotary shaft 2. An air cylinder 6, used for pressure-contacting, is fastened on an upper end thereof, and a pulley, provided with an electromagnetic brake 7, is secured on the shaft. A plastic tank 12, being a joining member, is pinched by means of the clamp 5. A pressurized fluid is then poured by pressure into the tank 12, and the rotary shaft 2 is lowered as it rotates. The bracket 4 is rotated in such as a state as pressure-contacts the surface whereat the tank 12 and the bracket 4 are joined together, and said joining surface is fused by the friction heat. And then, the bracket 4 is caused to stop rotating and the joining surface is cured for welding.

Abstract: PURPOSE:To keep an adjusting screw independent from the revolution of a plunger, by placing a variable discharge cam between the plunger and the adjusting screw. CONSTITUTION:A diaphragm 15 is displaced in accordance with the exhaust pressure of an engine, then a variable discharge cam 16 is transferred toward the direction corssig the axis of a plunger 9 to control the stroke of the plunger and change the amount of discharge. The forwarding of an adusting screw 18 can also displace the cam 16 to the plunger's axial direction to adjust the discharge. Since the variable discharge cam 16 is placed between the adjusting screw 18 and the plunger 9, the revolving force of the plunger 9 is not transmitted to the adjusting screw 18 to disturb the adjustment.

Abstract: PURPOSE:To permit automatic adjustment of the brake gap with such an arrangement that ratchet pawls respectively pivoted to a stationary frame and a rotary lever separate from an operating shaft for opening a shoe are engaged with a ratchet secured to the operating shaft. CONSTITUTION:When a solenoid is de-energized, a rotary lever 16 is rotated in the counterclockwise direction about a shaft 17, whereby a ratcket pawl 22 pivoted by a pin 23 to the rotary lever 16 causes rotation of a ratchet 15 to cause a rotary shaft thereof, i.e., operating shaft 14a, to have a brake action between a pair of shoes. When the brake distance between the shoes and drum is increased, the ratchet 15 is rotated to an extent in excess of the length L of a gear 15a, whereby a ratchet 24 pivoted by pin 25 to a stationary frame is engaged with the next ratchet tooth. Thus, at the time of releasing of the brake the return of the ratchet 15 is regulated to effect automatic adjustment of the brake gap.

The following relationships also apply, 4.6C + 1.05Mn + 0.54Ni + 0.66(Mo + W/2) + 0.5Cr + k ≥ 1.6, where k = 0 if the steel contains less than 0.0005% B and k = 0.5 if the steel contains more than 0.005% B and 0.6% ≤ (Al+Si) ≤ 2%. To improve their abrasion resistance sheets of the steel are heated to above austenisation temp. (e.g. 900 degrees C) then cooled to 450 degrees C at more than 1 degrees C/s, further cooled to 200 degrees C over 50 s to 60 minutes (pref. 100 s to 30 minutes) and finally returned to ambient (below 250 degrees C) in less than 3 h. This gives the steel a martensitic or martensitic-bainitic structure contg. 5-15% austenite and a hardness of 400-500 HB.

Abstract: A circuit and method for generating a checksum for a TCP packet on the fly. A stream of 32-bit data words from a TCP packet is split into two 16-bit data word streams and separately summed using 16-bit adders. The carry-out from the adders is tied to the carry-in thereof so as to incorporate any carry bits generated into the sum. At the end of the data stream, three further summing cycles are used in order to generate the final 16-bit one's complement checksum. First, the two 16-bit data stream partial sums are added together, including any carry bit from one of the adders while the carry-out from the other adder is stored. In the second cycle the stored carry-out and the carry-out from the first cycle are added into the sum. In the third cycle, any carry bit generated in the second cycle is added to the sum so as to produce the final checksum.

Abstract: PROBLEM TO BE SOLVED: To mount components with accuracy, without making equipment complicated by fixing the components on a body to be mounted with components by heating a suction nozzle by a laser, instead of an illumination light, which serves for a heating means for heating a suction nozzle as well as providing illumination light and, at the same time, heating the suction nozzle also from the side of the body to be mounted with components. SOLUTION: A suction nozzle 2 is heated by a CO2 laser 6, instead of illumination light for an image-pickup means 4, which serves for a heating means for heating the suction nozzle 2 as well as providing illumination light. Here, not only by the CO2 laser 6, is the suction nozzle 2 heated but in cooperation with the substrate 8 side to fix a component 1 onto the substrate 8. In this case, the position of the component 1 with respect to the suction nozzle 2 is detected by the image-pickup means 4. Based on a corrected value for the position of the component 1, a control section 12 is operated to drive an XY stage 10 and a Z stage 11, and the component 1 is positioned at a correct plate on the substrate 8. Then, an adhesive attaching to the component 1 is melted by heating from the substrate 8 side and transmission of heat from the suction nozzle 2.  Thereby, a component can be mounted with high accuracy and efficiency.

Abstract: PURPOSE:To improve the efficiency of wire bonding operation, by forming both of bonding and soldering surfaces on the opposite end faces of a post. CONSTITUTION:The main body 5a of a square-pillar-shaped post is made of a first metal having a soldering property, such as nickel, and wire-connecting parts 5b, which are jointed to the oposite end faces of the main body 5a of the post respectively, are made of a second metal which can be bonded with wires by ultrasonic bonding. Each wire-connecting part 5b has a smaller surface area than the opposite and faces 5A of the main body 5a of the post. Moreover, each wire-connecting part 5b is formed, for instance, in the shape of a strip having a smaller width than that of the end face of the main body 5a of the post, and is jointed to the central portion of each end face of said main body. Accordingly, a surface B to which the ultrasonic bonding can be applied is formed in the center of each end face of the wire bonding post 5, while a surface A to which soldering can be applied is formed on both sides of the surface B, and thus the soldering and the ultrasonic bonding can be applied to each of the end faces.
