IPC: C25D5/00
Filed: 1988-09-22
Abstract: PURPOSE:To form a high quality Bi-Sn alloy plating film on a body to be plated with satisfactory adhesion by electroplating with a plating bath contg. a Bi salt, a stannous salt and an inorg. acid by further supplying electric current to the body to be plated when the body is immersed in the plating bath and pulled up from the bath after plating. CONSTITUTION:A body to be plated is electroplated with a plating bath contg. about 5-30g/l (expressed in terms of Bi) Bi salt such as Bi2(SO4)3, about 1-6g/l (expressed in terms of Sn) stannous salt such as SnSO4 and about 50-400g/l inorg. acid such as sulfuric acid or org. sulfonic acid such as hydroxyalkanesulfonic acid. At this time, the body to be plated is previously connected to the cathode terminal of a rectifier connected to the anode and electric current is further supplied to the body to be plated when the body is immersed in the bath and pulled up from the bath after plating. The substitution deposition of Bi on the body to be plated and a formed Bi-Sn alloy plating film is prevented and the plating film is formed on the body with satisfactory adhesion.

Filed: 1983-12-16
Abstract: PURPOSE:To obtain an analog converting output with low cost and high quality by changing a stepwise output waveform by a D/A converter into a slow waveform through linear approximation while using a low-order LPF. CONSTITUTION:Digital data sampled and coded by a prescribed sampling frequency is converted into a step-shaped signal A of a level in response to each code by the D/A converter and sampled D, E by sampling signals B, C phase- shifted by T/2. Then a signal F from a substractor 13 is integrated (G) by an integration device 14, the result is added to a hold output E of a sample-and- hold circuit 12 and an analog signal output is obtained via an LPF16. Since generation of spurious radiation is decreased, the LPF of the next stage is enough for less number of stages.

Abstract: PURPOSE:To make switch operation fast by composing springs for energizing in the direction engaging a latch to a control bar of springs different in load, large and small, and making a spring smaller in load act at the time of engagement to the control bar. CONSTITUTION:When a make signal is input to energize an electromagnet 12, a rod 13 is moved to disengage an engaging part 8C from a roller 4, a latch 3 is disengaged from a pin 2, collides with a stopper 19 as pushing the first spring 18 having smaller load, the second spring 20 absorbs kinetic energy, and the latch 3 hits a control bar 1 and stops. The control bar 1 is released from engagement with the latch 3 and moves so as to make contact. When the make signal is remove to de-energize the electromagnet 12, the rod 13 is moved in the reverse direction, and then when a cutoff signal is input, the pin 2 of the control rod 1 moves to the position of the latch 3 for engagement, and locks the control bar 1. While the latch 3 and the pin 2 are in contact with each other, only the spring 18 having smaller load acts on the latch 3, and the spring 20 having larger load absorbs the kinetic energy generated by the high speed rotation of the latch 3.

Title: Semiconductor laser
Inventor: KOKUBO YOSHIHIRO
IPC: H01S5/00
Filed: 1986-10-07
Abstract: PURPOSE:To prevent noises due to the interaction of returning beams and internal propagating beams by forming first and second resonator regions mutually connected on both end surfaces of a resonator so as to shape an annular optical guide and a waveguide region leading out laser beams to the outside of a laser. CONSTITUTION:Beams moving forward in the clockwise direction or the counterclockwise direction on an annular optical guide shaped by first and second resonator regions 12a, 12b are each amplified lndependently, but only beams propagated in the counterclockwise direction on the annular optical guide are propagated over a waveguide region 13 and extracted as a laser beam output. Even when returning beams advance in the waveguide region 13 from the outside, the returning beams are coupled only with beams proceeding in the clockwise direction and amplified in resonator regions 12. Accordingly, the returning beams have no effect on beams amplified in the counterclockwise direction related to the laser output and do not generate interaction, thus generating no noise due to interaction.

Title: Probe for detecting position of three-dimensional free curved surface and work end part structure for working or the like of three-dimensional free curved surface
Inventor: SHINOHARA YOSHITO
IPC: G01B21/20
Filed: 1989-09-13
Abstract: PURPOSE:To obtain the position detecting probe which can measure easily X, Y and Z coordinates of the curved surface and can be handled easily by constituting so that a relative position of a detection point and a base part is not varied even if the attitude of the detection part is varied in accordance with the curved surface of the surface to be detected. CONSTITUTION:A base part 1 is attached to an orthogonal triaxial three-dimensional measuring machine. Subsequently, X, Y and Z of its measuring machine are moved so that the tip of a detecting part 5 comes into contact with a detection point A1 of the surface to be measured. Simultaneously, the base part 1 is turned around an axis so that the axis of the detecting part 5 coincides with the normal direction of the detection point, and also, a first link 2 is turned around the axis. Reading of X, Y and Z of the measuring machine in such a case is a measured value of the detection point A1, and also, reading of a rotation angle of a rotary dial plate 7 shows the normal direction of the detection point A1, respectively. In the same way, each point on the surface to be measured is measured successively. As a result, each link 2 cannot further rotate to the right. Therefore, by rotating the base part 1 by 180 deg., each point of the surface to be measured can be measured. Also, in the work end part structure, a working part or a processing part is placed instead of the detecting part 5.

IPC: G06F15/00
Filed: 1989-09-14
Abstract: PURPOSE:To perform a communication service process at a high speed and with high efficiency by dynamically keeping the number of processes set under the service execution request waiting state within a fixed range at execution of the communication service process. CONSTITUTION:In a process S100, the number of service processes set under the communication service execution request waiting state is monitored. In a process S101, a new service process is started when the number of the service processes is decreased down to a prescribed lower limit level or less and the service processes are supplied. In a process S102, the extra service processes are eliminated when the number of the service processes exceeds a prescribed upper limit level. Thus the number of necessary service processes in the execution request waiting state is always kept within a prescribed upper/lower limit level. As a result, the execution of service is secured without performing a process having a large overhead despite concentration of requests. Then the communication service process is attained at a high speed and with high efficiency.
