Title: Connecting structure between printed circuit board and connector
Inventor: NATSUME SHIGEO
IPC: H05K3/34
Filed: 1989-03-20
Abstract: PURPOSE:To achieve stabilized quality and improved reliability concerning connection between a printed circuit board and a connector by forming a bulge which accepts excessive solder in part of a connector terminal. CONSTITUTION:A semi-circular shaped bulge 3 is formed on a terminal 2, which forms a parallel contact portion 6 with a conductor wiring terminal portion 4 of a printed circuit board 5 on both sides of its bulge portion 3 when a connector 1 is installed. The other end of the terminal 2 has a configuration which permits it to engage with a plug terminal pin of a male-type connector 100. To secure the connection between the terminal portion 4 and the terminal 2, a drop of solder paste is allowed into the left-hand portion of the bulge 3 and applied there. Subsequently, the assembly is placed in a vapor phase reflow device for heat treatment, then taken out to cool. As a result, any excess solder is accepted by the bulge 3 as excessive solder 8, eliminating the possibility of its intrusion into the interior of the connector 1.

CONSTITUTION:For a picture recording magnetic head of a VTR, etc., a C type core 11 is made of an amorphous alloy magnetic member (an alloy having high hardness and wear resistance which is obtained by giving the ultraquenching to the molten matal of three transition metallic components of Fe, Co and Ni plus the submetallic component of Si, B, etc.). Then these two cores 11 are butted with each other via a nonmagnetic film 14 and pressed from both sides as shown by arrows to be stuck to each other. An oxidized metal of TiO2, etc. is formed as a reinforcement member 13 across the flat area including at least the tape travelling side surface on the side surface of the core 11 by the plasma melt- spray process. In such constitution, the large output voltage which can cope with the high frequency is obtained. As a result, a picture recording magnetic head of high strength is produced to obtain a high-contrast image.

Title: Semiconductor external storage controller
Inventor: KANEKO YASUO
IPC: G06F12/16
Filed: 1982-04-24
Abstract: PURPOSE:To prevent the generation of an incidental accident and to improve reliability of the titled controller, by providing a flip-flop which performs the reading control of an external storage device, a pulse generator, and the 1st and 2nd gates which deliver the 1st and 2nd reading requests respectively. CONSTITUTION:An external storage controller 2 checks a command given from a main body. When a command is detected, the controller 2 saves the contents of an address register 22 to a main control part 21 and at the same time resets the contents of a flip-flop 41 to stop the reading action to an external storage device. After a control is given based on the command, the contents saved to the part 21 are set again to the register 22. Then the flip-flop 41 is set. Thus a reading request is given to the external storage device via an AND gate 43 and an OR gate 44 with the pulse given from an oscillator 42. Then the reading data is checked and corrected and then written again to the same address. This can prevent an incidental accident at an address having a low frequency of access.

Filed: 1986-03-27
Abstract: PURPOSE:To obtain a high accurate tracking error signal by permitting a four- split light detector to receive reflected light beams from a reflection-type diffraction grating lens installed on an optical path from a semiconductor laser to an objective lens and calculating a difference signal between the outputs of two sets of detectors. CONSTITUTION:The objective lens 12 condenses light beams coming out of the semiconductor laser 1 on a disk 5. The reflection-type diffraction grating lens 13 is installed on the optical path covering from the laser 1 to the lens 12, and the reflected light beams are detected by the four-split light detector 14. It is disposed at the position of a minimum blur circle 20 so that the dividing line l1 of the detector 14 can be almost in parallel with a plane made by optical axes 15 and 16, and simultaneously the disk 5 is disposed so that a recording disk image can be in parallel with the division line l1. Then the difference signal between the AND signal output from the detectors 14a and 14b and that from the detectors 14e and 14d is obtained, and taken for the output signal of an error signal detection circuit 25. Thus a tracking error signal can be detected even if the oscillation wavelength of the laser 1 changes.

Title: Foreign matter presence/absence inspecting device
Inventor: UKON JUICHIRO
IPC: G03F1/00
Filed: 1988-03-19
Abstract: PURPOSE:To securely detect only foreign matter by providing a conjugate detection optical system which shares an optical path with an incidence optical system and also providing a signal processing circuit which decides that there is foreign matter only when both detection and conjugate detection optical systems detect reflected scattered light. CONSTITUTION:The conjugate detection optical system C is provided which shares the optical path with the incidence optical system A through a half-mirror 10. Reflected light R from the circuit pattern on the surface of a substrate O to be inspected has fixed directivity and is detected by the prescribed detection optical system B and optical system C according to the edge angle of the pattern. When there is foreign matter on the substrate O, on the other hand, the reflected light R is scattered in all directions regardless of the edge angle of the pattern and detected by all of the photodetectors 9A, 9B, and 13 of the optical systems B and C. Therefore, only when the optical systems B and C detect the reflected scattered light, the signal processing circuit decides that there is the foreign matter, so that only the foreign matter is securely discriminated and detected.

Title: Rotation regulator
Inventor: HABUTA HIROSHI
IPC: F16H31/00
Filed: 1987-03-24
Abstract: PURPOSE:To secure a nonengagement state positively, by rotatively energizing the polygonal cam member attached concentrically to a ratchet pawl, in a direction where any rotation is checked in a state of being engaged with a ratchet gear, with an energizing device. CONSTITUTION:In the state that ratchet pawls 59 and 60 are engaged with ratchet gears 56 and 57 by springs 62 and 64, a cam body 53 cannot be rotated, but a square cam body 58 rotates and energizes the cam body 53 to make it turn to the left by a plate spring 61. And, when the ratchet pawl 59 is rotated against the spring 62 by a lever 63, its engagement with the ratchet gear 56 comes off, whereby only anticlockwise rotation in the engaging direction is checked, but the reverse direction is freely rotated in the wake of external force to the cam body 53. And, when a lever 66 is rotated by a solenoid 65 against the spring 64, engagement between the ratchet pawl 60 and the ratchet gear 57 comes off, and only clockwise rotation in the engaging direction is checked, thus rotation in the reverse direction comes free. Thus, a rotatable state is securable with temporary drive of the solenoid.
