Title: Composite type magnetic head
Inventor: KUBO TSUYOSHI
IPC: G11B5/60
Filed: 1991-09-26
Abstract: PURPOSE:To provide the composite type magnetic head which realizes a narrow track width of <=10mum by machining with the composite type magnetic head for recording and reproducing to be used for a hard disk drive device. CONSTITUTION:This magnetic head is constituted by inserting a composite core chip 4 formed by sticking a reinforcing material 3 to one flank of the core chip 2 and working one end of the core chip 2 to <=10mum thickness by machining into a slit groove 6 provided on a slider 5. Since the reinforcing material 3 reinforces the strength of the core chip 2 according to this constitution, the working down to <=10mum thickness by the machining is possible. The composite type magnetic head having <=10mum track width which has heretofore been difficult with a method using the machining is realized by the method using the machining.

Title: Operation testing apparatus for transfer for four-wheel drive
Inventor: ODA YOSHIHIKO
IPC: G01M13/02
Filed: 1989-09-22
Abstract: PURPOSE:To discriminate driving conditions by measuring the vibrations of transfer casings different from each other between a two-wheel drive and a four-wheel drive even though the numbers of revolutions are the same as each other. CONSTITUTION:A transfer 10 is placed on a bed portion 20, positioned by the clamper 33 of a driving portion 30 to be fixed and the input shaft 11 of the transfer 10 and a driving shaft 31 are connected to each other in engagement. A vibration sensor 24 is moved to abut against the outer surface of the casing of the transfer 10 and the input shaft 11 is driven for rotation by a motor 34. When the transfer 10 is changed over from a two-wheel drive to a four-wheel drive by a changeover operating unit 40 and only a rear side output shaft 12 or both an output shaft 12 and a front side output shaft 13 are driven for rotation, a distinct difference is generated in the output of the sensor 24. Thus, a comparator 51 compares a measured result and a reference value with each other and judges the two-wheel drive or the four-wheel drive, thereby performing the operation test of an engine switch.

Title: Photosensor
Inventor: KUBO HIROAKI
IPC: H01L31/10
Filed: 1988-09-30
Abstract: PURPOSE:To detect infrared rays accurately and with good sensitivity by a method wherein a filter layer used to cut off light in a visible-ray region from the incident side of light and a fluorescent substance layer are formed on one main face of a transparent substrate. CONSTITUTION:Light of a wavelength in a visible-ray region, e.g., light (region B) of 700nm or lower, is cut off by a visible-ray cutoff filter layer 3. Accordingly, this sensor does not react at all to the light of the wavelength in the visible- ray region by direct irradiation. Then, light of a wavelength other than light of the wavelength in the visible-ray region, e.g., light (region A) in a long- wavelength region of 700nm or higher, reaches a fluorescent-substance layer 6; the fluorescent substance layer 6 is excited; a light energy of the wavelength (region A) according to a spectroscopic sensisivity of an amorphous silicon semiconductor layer 3 is radiated toward the amorphous silicon semiconductor layer 3. That is to say, the light in the long-wavelength region is converted into a wavelength according to the spectroscopic sensitivity of the amorphous silicon semiconductor layer 3. Thereby, only infrared rays are detected.

Title: Manufacture of injection molded article with hollow shape
Inventor: ASAO TOSHIHIRO
IPC: B29C45/17
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To close off a gas inflow port without increasing cost by injecting resin again after gas injection molding and closing off the gas inflow port. SOLUTION: Gas is injected from a gas gate 9 so as to make resin within the cavity 3 into a hollow shape. Molten resin is injected from the injection molding machine 1 and comes into the cold runner 5 from the second gate 6 to be filled in the hollow part. At this time, since the check valve within the gas nozzle 8a comes to be in a closed condition, molten resin does not comes into the gas nozzle 8a. In addition, molten resin comes into the hollow part of the cavity 3 via the first gate 4. In this instance, resin coming into the cavity 3 does not need to fill the hollow part, thus it is sufficient to be a quantity capable of closing off the first gate 4.

Abstract: PURPOSE:To obtain a wide dynamic range, simplify constitution, and facilitate the formation of a complementary MOS integrated circuit by raising input digital data which is raised to the (1/n)th power to the (n)th power through a digital/ analog converter. CONSTITUTION:A 16-bit digital audio signal is processed by a digital signal processor DSP11 for extraction of square root to obtain an 8-bit compressed signal. This is loaded in a counter 53 through a shift resistor SR51 and clock pulses begin to be counted; and an integrator 7 integrates the output current I of a constant current 55 and the output 1/2I.TF<2> of the integrator 7 is obtained at the point TF of point when the contents of the counter 53 attain to 0. The square- law D/A conversion is carried out, so the wide dynamic range is obtained. Further, complementary MOS IC implementation is facilitated because a single constant current power source is used.
