Patent JP-H04186742-A (JP)
Title: Circuit board for flexible tab
Inventor: KOBAYASHI TOSHIHIKO
IPC: H01L21/60
Filed: 1990-11-20
Abstract: PURPOSE:To prevent generation of whisker without reducing bonding property and enable reliability to be improved by using a solder plating with a relatively low content of lead at an inner lead part and a solder plating with a relatively high content of lead at an input terminal part. CONSTITUTION:Solder plating closer to tin having 2-15% content of lead is performed to an inner lead part 1, an input terminal part 2, and an output terminal part 3. The reason for using solder plating with a low content of lead ranging from 5 to 15% is to form a shape close to a eutectic of gold tin which is established by a conventional technology for securing bonding property with an IC and to prevent generation of whisker of tin. Then, plating closer to eutectic solder with a content of lead ranging from 40 to 60% is performed to the input terminal part by a partial plating system. Thus solderability to other substrate can extremely be improved.

Title: Optical axis fine adjustment device for optical scanning system
Inventor: WAKAI HIDEKI
IPC: G02B26/10
Filed: 1992-11-02
Abstract: PURPOSE:To extremely accurately and easily perform the fine adjustment of the optical path of scanning synchronizing light by turnably arranging an optical member on an axis perpendicular to a scanning plane. CONSTITUTION:Synchronizing light emitted from a light source 5 is reflected on one plane of polarization of a rotary polygon mirror 6 and made incident on a synchronizing light detecting sensor 11 through a reflection mirror 9 and an optical element 10 so as to be detected. The optical element 10 is arranged between the mirror 9 and the sensor 11 and can be rotated and moved around the axis perpendicular to a scanning direction X or the scanning plane. The optical element 10 has refractive index different from peripheral space, and is provided with an incident surface and exiting surface for the scanning synchronizing light. A laser beam L emitted from a light source 1 is guided to one plane of polarization of the mirror 6. The laser beam reflected on the reflection surface passes through an image-formation optical system 12, scans a photosensitive body 4 with the rotation of the mirror 6, and is formed into an image on a photosensitive surface 13. Therefore, the path of the scanning synchronizing light is correctly adjusted by the optical element 10, so that the synchronism is accurately performed.

Title: Magnetic head
Inventor: MIYAGAWA HIDEAKI
IPC: G11B5/23
Filed: 1993-12-16
Abstract: PURPOSE:To obtain a magnetic head having a constitution which can improve both of the reproducing efficiency and the recording efficiency of a magnetic head in a short wavelength range by narrowing a gap. CONSTITUTION:A layer-built element which composed of a ferroelectric thin film 33 and conductor thin films 32 and 32 between which the thin film 33 is sandwiched is provided in the magnetic gap 3 of a magnetic core composed of core halves 1 and 2. A voltage is applied between the conductor thin films 32 and 32 which are used as electrodes through lead wires (not shown). The thickness of the ferroelectric thin film 33 is increased by a piezoelectric effect caused by the voltage application to increase the gap width of the magnetic gap 3. Moreover, a pressure produced by the increase of the thickness of the thin film 33 is applied to the butting parts of the magnetic core which face the magnetic gap to decline the permeability of those parts substantially and the gap width is practically increased further. That is, the gap width can be varied by the existence of the voltage application and the magnitude of the applied voltage.

Abstract: PURPOSE:To facilitate positioning of a cutting tool and also shorten the time required for processing works by supporting a shaft holding portion to a first holder in such a manner as being moveable perpendicular to the axial direction of the main spindle of the cutting tool, and also supporting a tilting shaft by means of a spherical bearing to a second holder fixed to the shaft holding portion. CONSTITUTION:When the center line of a lower hole H provided through a work W is not identical with that of the main spindle 1 of a machining tool, a shaft holding portion 3 is supported by a thrust bearing 36 together with a tilting shaft 7 and a second holder 5 via a socket 9 and bends a compression spring 33 and is horizontally moved by the distance between the respective center lines of the lower hole H and the main spindle 1. when the main spindle 1 is rotated a ball 4 transmits torque to the shaft holding portion 3 while rolling, because though the centers of rolling channels 23 and 33 are not identical with each other the ball 4 is fitted in both channels 23, 33. The shaft holding portion 3 is rotated while being eccentric with respect to the main spindle 1. When a cutting tool 8 is pulled after processing the work W, the shaft holding portion 3 is horizontally moved by the compression spring 33 by the distance between the respective centers of the rolling channels 23 and 33 and returns to its original point.

Title: Decoder
Inventor: WATABE AKIHIRO
IPC: H04N19/189
Filed: 1999-11-08
Abstract: PROBLEM TO BE SOLVED: To realize high-speed reverse reproduction of MPEG data or the like with a memory of a small capacity. SOLUTION: An input bit stream is written in a bit buffer 102. Data in the bit buffer 102 are decoded before reverse reproduction and a head address of each frame in the bit buffer 102 is stored in an address storage section 106. In the case of reverse reproduction, a buffer management section 110 supplies only data of a required frame for data decoding from the bit buffer 102 to a decoding section 105 on the basis of the head address of each frame stored in the address storage section 106. Since the bit buffer 102 stores the bit stream (compressed data), the capacity is small in comparison with storing a decoded image.

Filed: 1994-12-20
Abstract: PURPOSE: To provide a motor which can prevent the appearance of a waving sound which is caused by a change in the number of rotations. CONSTITUTION: A DC brushless motor has a power circuit 3 which obtains DC power from an AC power supply 4, a conduction controlling section 10 which supplies DC power to a preliminarily selected stator winding in response to a timing signal generated based on a signal which is obtained when a rotor passes a specified rotation position, and a correcting section 14 which corrects the generation time of the timing signal which is generated based on the signal when a change in the number of rotations of the rotor exceeds a specified speed of change. Due to this structure, a change in the number of rotations of the rotor due to a sharp change in supply voltage can be prevented and the appearance of a waving sound caused with the change in the number of rotations can also be prevented.

Filed: 1992-11-26
Abstract: PURPOSE:To provide a sheet feeder which can ensure stable registering from thin paper to thick paper, guide even curled paper completely to a register roller nip part, and form slackness. CONSTITUTION:A thick paper regulating guide plate 7 is constituted of light- weight material so as to oscillate, and a clearance between the end of a paper sheet and a stationary guide plate is kept small until it has run against a register roller nip part.

Title: Method and apparatus for regulating of charging phase of ink drop
Inventor: TOURAI YUTAKA
IPC: B41J2/115
Filed: 1988-12-15
Abstract: PURPOSE:To charge a drop in an optimum state and to record a satisfactory image by detecting the generation of an improperly charged drop, and deviating the phase of a clock signal and the phase of an ON-OFF operation control signal relatively by the half period of the clock signal in response to the detection. CONSTITUTION:When an improperly charged drop is generated, a LED 20B emits a light. Accordingly, an operator visually recognizes the light emitted from the LED 20B to confirm the generation of the improperly charged drop. When a clock signal delayed through 1/2 clock delay circuit 11 is input to a synchronizer 16, a charge signal becomes an outputting state according to a signal deviated by half period by the clock signal. When an image recording operation is executed in this state, only the noncharged drop is arrived at a printing sheet P to be printed. As a result, since the forming timing of the drop is set accurately at the intermediate point between the rising and falling timings of the charge signal, its printing quality is extremely improved.
