Title: Manufacture for metallic thin film magnetic recording medium
Inventor: WATANABE SEIZOU
IPC: C08L67/02
Filed: 1981-08-10
Abstract: PURPOSE:To inexpensively obtain a metallic thin film magnetic recording medium having cracks in a magnetic substance layer and excellent running performance, by applying tension exceeding the heat shrinkage rate in the lengthwise direction of a base in  the lengthwise direction of the metallic thin film magnetic recording medium. CONSTITUTION:A metallic thin film magnetic recording medium 20 is formed with a  polyethylene terephthalate base of about 6mum thickness, for example, and a magnetic  substance layer formed on the base. In heat treatment of the recording medium 20  with a heat roller 14, tension is exerted in the lengthwise direction of the recording  medium 20 by adjusting the rotating speed of a payoff shaft 12 and a winding shaft 16.  The tension exerted on the recording medium 20 is set greater than the heat shrinkage  rate in the lengthwise direction of the base. Then, the base of the recording medium 20  heated with the heating roller 14 is thermally shrunk only to the broadwise direction  without being thermally shrunk in the lengthwise direction. Through the thermal contraction of the base of the recording medium 20 only to the broadwise direction,  cracks in the lengthwise direction, i.e., almost in parallel with the recording direction  are generated on the magnetic substance.

Title: Memory controller
Inventor: HATANAKA MITSUYOSHI
IPC: G11C11/407
Filed: 1980-09-10
Abstract: PURPOSE:To facilitate the timing control and at the same time realize the free setting of the timing for a memory, by generating a timing signal based on the control timing information which is stored in the memory. CONSTITUTION:With arrival of a memory start signal SSS, a counter K1 counts the reference clocks SCL. When this count value is equal to the value of a register R1, a control circuit S2 is started with the output of a comparator H1. As a result, the register CR1 is set to deliver a low address signal. Other outputs of the register CR1 control a multiplexer M1 and supply the value of a register R2 to the comparator H1. In case the count value of the counter K1 is equal to the value of a register R3, an address switch signal is produced from the CR2. When the value of a register R5 equals the count value of the K1, a column address signal is produced from the R3 to execute the timing of the memory reading. Then the data is read out of the memory.

Title: Valve characteristic controller for internal combustion engine
Inventor: SUGIMOTO ATSUSHI
IPC: F01L1/34
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a simple valve characteristic controller for moving a camshaft having three-dimensional cams axially and rotating the camshaft relative to a crankshaft with the use of a ring gear. SOLUTION: An axial drive mechanism 29 displaces an intake camshaft 22 axially and varies the working angles of three-dimensional cams 27. That displacement establishes the engagement of the splines of the camshaft 22 with the internal teeth of a ring gear to allow the camshaft 22 to move axially with respect to a pulley 24a synchronizing with a crankshaft 15. A rotative drive mechanism 24 displaces the ring gear axially and then establishes the engagement of the helical splines of the pulley 24a with the external teeth of the ring gear and that of the splines of the camshaft 22 with the internal teeth of the ring gear to thus allow the camshaft 22 to rotate relative to the pulley 24a.

Title: Ink jet recorder drive method
Inventor: ABE NOBUMASA
IPC: B41J2/035
Filed: 1985-06-10
Abstract: PURPOSE:To realize an ink jet recorder drive method with low power consumption and less driving waveform distortion, by a method wherein the shape of ink meniscus formed at an ink discharge port is varied by an electrostatic force generated between ink and an electrode provided on the front surface of an air discharge port. CONSTITUTION:An air flow fed from an air supply source 1 to a head at a constant rate of flow is jetted from an air discharge port 2 after being abruptly bent at the vicinity thereof. The bias voltage of positive polarity Vb is applied on the ink having supplied to the vicinity of an ink discharge port 3 forced by the back pressure from the air supply source 1, and on the other hand, the voltage of positive polarity Vs, which is lower than the Vb, is applied on an electrode 4 mounted on the board having the air discharge port 2, and the resulting bias electrostatic force generated in Vb-Vs region acts on ink to form ink meniscus. Turning of the transistor 6 ON by the signal from a drive signal generating circuit 5 causes the abrupt reduction of Vs to approximate 0V with the raise of the electrostatic force acting to the ink meniscus up to the electrostatic force produced by the Vb, thus pulling ink until it reaches a recording surface 7 in a stringy form by use of pressure change in the air flow.

Title: Semiconductor device
Inventor: MOROI SADAYUKI
IPC: H01L23/12
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To prevent foam from remaining in solder, and to improve junction strength by setting the cross section shape of a through hole being used as a solder ball connection part to a non-circular shape where at least one part projects outside. SOLUTION: When the cross section shape of a through hole 2 is set to a non-circular shape, a gap that is not brought into contact with a solder ball 4 is formed at least one part of the periphery of the solder ball 4 while the spherical solder ball 4 is accommodated in the through hole 2. In this state, for example, an entire body is heated to the fluxing temperature of the solder ball 4 for fluxing by a method such as infrared reflow. At this time, the gap being formed between the inner-wall surface of the through hole 2 and the surface of the solder ball 4 operates as a relief path for relieving flux being vaporized by heating to the outside from space being surrounded by the inner- wall surface of the through hole 2, a land pattern 3, and the solder ball 4, thus preventing the space from being formed by remaining in the solder ball after fluxing and hardening.

Title: Method for correcting offset of tracking error signal
Inventor: YAMAMOTO TAKEHARU
IPC: G11B7/09
Filed: 1995-05-25
Abstract: PURPOSE: To highly precisely correct an offset of a tracking error signal generated by variations of a disk or a head. CONSTITUTION: Under the state of tracking control, a switch 128 is opened to unoperate transfer control, and a lens is shifted by a track-jump. Under this state, a signal of a differential amplifier 211 in a mirror part is held by a sample-and-hold circuit 212 to measure an offset of the mirror part. Then, a peak value and a bottom value of the signal of the differential amplifier 211 at the time of a still-jump are measured by a peak and bottom detecting circuit 125 to obtain their individual offsets of the tracking error signal, and an amplification factor of a variable amplifier 113 is decided based on these two offset values. By this method, the offset of the tracking error signal can thus be corrected with high precision.

Title: Wire bonding apparatus
Inventor: ODAGIRI MASAO
IPC: H01L21/60
Filed: 1988-05-24
Abstract: PURPOSE:To prevent the deformation of an inner lead in wire bonding, by forming a recess part in the surface of the stage so that at least the tip part of the rear surface of the inner part is not in contact with the surface of a stage. CONSTITUTION:A recess part 32 is formed in the perpendicular direction with respect to the extending direction of an inner lead 4a at the outside of a positioning projection 31 in a stage surface F. The stage surface F is not in contact with the inner lead 4a at the tip part of the inner lead 4a owing to the recess part 32. Even if the plated material at the tip of the inner lead 4a is fused due to the heating of a lead frame 4 and moved into the rear side of the inner lead 4a, the non-contact state between the tip part of the rear surface of the inner lead 4a and the stage surface F is maintained with the recess part 32 which is formed in the stage surface F. Therefore, junction between the inner lead 4a and the stage surface F through the plated material is prevented. Thus, the deformation of the inner lead 4a is prevented, and a highly reliable semiconductor device can be obtained.
