Title: Production of surface blackened solder wire and surface blackened solder wire
Inventor: KAWAGUCHI TORANOSUKE
IPC: B23K35/36
Filed: 1994-05-26
Abstract: PURPOSE:To obtain a surface blackened solder wire in short heating time by previously providing the surface of a solder wire with a metallic layer which is blackened by sulfiding and exposing the surface to an S-contg. gas or liquid. CONSTITUTION:The surface of the solder wire for joining metals is provided with the metallic layer of Cu or Ag or the like which is blackened when sulfided. Such solder wire is exposed into the gas contg. S; for example, hydrogen sulfide, by which the black sulfide layer is formed on the surface. The surface may be otherwise exposed into the liquid, powder or fluid contg. the S. The metallic layer is formed by plating, applying, sputtering, etc. The thickness of the sulfide layer to be formed on the surface of the solder wire is adequately about 0.01 to 3mum. As a result, the heating time at the time of heating the solder wire by using a laser beam is shortened and the rapid soldering is made possible.

IPC: B41J2/295
Filed: 1989-05-30
Abstract: PURPOSE:To keep leaf springs from damage or corrosion due to splashing to enhance the durability of leaf springs by coating the leaf spring with a film before performing the separating processing of a frame and a movable element in the manufacture of the motion converting apparatus utilizable in the preparation of a printing head. CONSTITUTION:A frame main body 31 integrally having a main frame 2, a base part 3, a movable element 5 and a bus-frame 4 is formed from a metal material such as an Invar alloy. Next, one end parts of both leaf springs 6, 7 integrally having a tilting body 8, a tilting arm 10 and a printing wire 1 are inserted in the mounting groove 32 of the frame main body 31 to be fixed thereto by soldering. Silicone rubber is applied to the part between both soldered leaf springs 6, 7 and the peripheries thereof to form a film 35. Thereafter, the separating groove 33 between the main frame 2 and the movable element 5 and the separating groove 34 separating the mov able element 5 and the sub-frame 4 are formed by laser processing or wire cutting discharge processing to be divided. Since the silicone rubber is preliminarily applied to the leaf springs 6, 7 as mentioned above, even when the refuse generated by wire cutting discharge processing or laser processing is scattered, the leaf springs 6, 7 are not injured.

Title: Synchronizing code detection circuit
Inventor: SHIBUYA AKIHIRO
IPC: H04J3/06
Filed: 1986-06-12
Abstract: PURPOSE:To detect a synchronizing signal by a few number of constituents, by multiplexing plural input code groups by every bit, and comparing an output after multiplexing, with a prescribed synchronizing signal detecting signal. CONSTITUTION:Inputted plural input code groups are multiplexed by every bit by a multiplexing circuit 1. The output is compared with the prescribed synchronizing signal detecting signal at the first comparator 2, and also, it is code-converted at a code converter 4. By comparing the sizes of a code- converted conversion signal, and a prescribed conversion signal at the second comparator 6, a specific synchronizing code is outputted from the plural input code groups. Thereby, since the circuit 1 multiplexes the input code group corresponding to synchronizing codes included over entire plural input code groups, the constitution of a detection circuit, etc., can be simplified.

Title: Dc motor driving valve
Inventor: SATOU TADASUKE
IPC: F02M25/07
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To easily and accurately sense a positionof a valve which is driven by a DC motor by driving a valve by means of a DC motor through a transmission member installed on a rotary shaft of the DC motor, and arranging a control part of the DC motor and a position sensor of the valve using ripple waves of the DC motor. SOLUTION: Torque of a DC motor 10 rotates a shaft 62 by means of a worm gear (transmission member) 66, and transmitted to a shaft 58. In an intake valve 50, a shaft 58 is moved upward, separated from a valve seat 56 for communicating an intake passage 52 with an intake passage 54. When the shaft 58 is moved downward, and communication between the passages 52, 54 is interrupted. A control mechanism 12 is provided for rotationally driving the DC motor 10 which counts ripple waves output from a ripple terminal until inertial rotation is stopped. When the inertial rotation of the DC motor 10 is stopped, error between a desirable position of the intake valve 50 and the position where the intake valve 50 actually stops is computed from the counted number of the ripple waves.

Title: Ras circuit
Inventor: OZAWA SUMIO
IPC: G06F11/22
Filed: 1983-07-26
Abstract: PURPOSE:To obtain a simple circuit which secures reliability by ORing the output of an FF which receives a diagnostic result signal as a set or reset input and a system start signal as the reset or set input with the system start signal. CONSTITUTION:When the system start signal 14 goes down to a level L, a self- diagnosing circuit 8 is actuated to reset a peripheral circuit 10, and the signal 12 sets an FF12 to the level L at the same time, so the FF is fixed at the level L by a driver element 15 connected to the Q output. When the diagnosing operation is completed normally, a diagnostic result output signal 13 goes down to the level L to hold the Q output of the FF12 at a level H, and the signal 14 is returned to the level H. If a fault is found, on the other hand, the signal 13 goes up to the level H, the signal 14 is held at the level L, and the circuit 10 is still reset. Consequently, the circuit (RAS circuit) for securing the reliability has no special input/output pin and the system start signal 14 is only utilized, so large practical effect as for a microprocessor is obtained.

Filed: 1987-05-30
Abstract: PURPOSE:To realize an access to a real memory with no address conversion after deciding whether or not a logical address is kept within a real memory range decided previously within a real memory and performing an access to the real memory via the logical address. CONSTITUTION:A logical address used by a program language is inputted for access of a real memory 4. When a deciding means 6 decides that the logical address is kept within a real memory range decided previously, the logical address is used for access of the memory 4 via a selector 8 as a real address. Otherwise an address obtained by converting the logical address via an address converting means 2 is used. Thus it is possible to satisfy a request for a face that a high-seed access is realized and the storage contents are protected by a virtual memory.
