Title: Thin film magnetic head
Inventor: YAMADA TADAHARU
IPC: G11B5/245
Filed: 1984-12-27
Abstract: PURPOSE:To obtain a thin film head provided with both a high read-out performance and a high write performance under recording of a high density by providing an auxiliary magnetic pole so as to be adjacent to a main magnetic pole having an exciting coil layer. CONSTITUTION:The titled magnetic head has a substrate 21, an insulating layer 17 and 18, a lower main magnetic pole 11, an upper main magnetic pole 12, coil 15 and a recording and reproducing gap 16, and a lower auxiliary magnetic pole 13 and an upper auxiliary magnetic pole 14 are provided through the insulating layer 17 on the lower main magnetic pole 11 and the upper main magnetic pole 12, respectively. As for the thin film head, at the time of write, both the main magnetic pole 11 and 12, and the auxiliary magnetic pole 13 and 14 are excited by a powerful magnetic flux generated by a current flowing to the coil layer 15, and a powerful write magnetic field Hw can be generated. At the time of read-out,a magnetic field generated from a recording medium is small as <= about 1/3 of the write magnetic field, therefore, by a gap of the auxiliary magnetic pole and the main magnetic pole, the magnetic flux in the lower auxiliary magnetic pole 13 and the upper auxiliary magnetic pole 14 is cut off and does not reach the main magnetic pole.

Title: Facsimile equipment
Inventor: KANBARA TAKAAKI
IPC: H04N1/00
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To obtain a compact facsimile equipment that an ink cartridge is easily exchanged by providing an auxiliary platen functioning as an original tray for assisting a platen at the opened position, and as a cover covering the upper face of the device at the closed position. SOLUTION: At the time of exchanging an ink jet cartridge, a turning supporting point of an auxiliary platen 3 functioning as an original tray at the opened position is provided at a platen 2. When this platen 2 is turned backward, the auxiliary platen 3 is turned backward according to the turning operation. The maximum limit of the angle of turning of the auxiliary platen 3 is limited so that when the auxiliary platen 3 is present at the closed position, the platen 2 can be fixed to the closed position, and the turning can be limited. Thus, the platen 2 can be prevented from erroneously being opened at the time of using the auxiliary platen 3 as an original tray. Thus, a non-defective and convenient cartridge exchanging function can be realized in this compact facsimile equipment.

Title: Temperature drift tester of semiconductor apparatus
Inventor: ASAZUMA SADAHIRA
IPC: G01R31/26
Filed: 1987-11-07
Abstract: PURPOSE:To perform a drift test in low cost with high accuracy, by using the transient heat resistance characteristic of the package of a device to be measured to apply high power within the tolerant limit thereof for a short time and measuring drift quantity. CONSTITUTION:A tester is constituted of a power device 1 having reference voltage 3, a set variable current source 8, a voltmeter 9 equipped with a measuring strobe and a power supply 10. Now, when transient heat resistance at a long time t2 is set to K2, the rise DELTAT2 in the temp. of a pellet at this time becomes DELTAT2=Pd/K2 (Pd; rated power). When a test is performed in such a state that a test time is set to t1, the transient heat resistance at the power applying time t1 is K1 and, therefore, power PdM to be applied necessary for obtaining the rise in the temp. DELTAT2 under said condition becomes PdM=DELTAT2/K1. As a result, when power supply voltage VCCA and a current I2 variable externally are set so as to satisfy DELTAT2/K1=VCCAXICCA+VCCAXI2, the rise in the temp. of the pellet of the device to be measured approaches that of the device to be measured when prescribed power is applied for the time t2 and a highly accurate drift test can be performed within a short time.
