Title: Frequency adjusting method of piezoelectric vibrator
Inventor: TSUJI MASATO
IPC: H03H3/04
Filed: 1984-03-30
Abstract: PURPOSE:To adjust accurately a frequency into the allowable range of a rated resonance frequency by subjecting piezoelectric vibrators, whose frequencies are outside the upper limit value and the lower limit value of the rated resonance frequency, to the first fine frequency adjustment from one frequency region to the other frequency region and subjecting these piezoelectric vibrators to the second fine frequency adjustment together with piezoelectric vibrators whose frequencies are included in the other frequency region from the first. CONSTITUTION:A piezoelectric vibrator 4 consists of a piezoelectric substrate 1 chipped from a wafer into a stripe shape and a pair of exciting electrodes 2a and 2b which are arranged to face main surfaces 1a and 1b facing each other of the substrate 1. In the first frequency adjustment, an insulating film which has 4,000-8,000Angstrom  thickness and consists of an SiO2, Si3N4, or the like is stuck uniformly to all vibrators 4 requiring adjustment without observing resonance frequencies. Next, piezoelectric vibrators 4 whose frequencies are moved from the first frequency region I to the second frequency region II are subjected to the second frequency adjustment, where frequencies are adjusted into the allowable range of a rated resonance frequency F0, together with piezoelectric vibrators 4 whose frequencies are included in the second frequency region from the first. In this frequency adjustment, four edge lines 5a-5d forming longer sides of the stripe-shaped substrate 1 are chamfered.

Title: Winding method of magnetic head
Inventor: TOMITA SUNAO
IPC: G11B5/17
Filed: 1984-03-30
Abstract: PURPOSE:To improve the winding workability of a magnetic head by checking the defective insulation and a disconnection of a wire in its winding process and at the same time measuring the inductance. CONSTITUTION:When a wire 4 is wound round a core chip 2, an end 4a of the wire 4 is fixed to a wire fixing part 12 with the other end 4b set free. In this case, the insulation resistance of the wire 4 is measured by actuating the 1st measuring instrument 14 to apply the measurement voltage between the chip 2 and the part 12 via a head base 1. While the 2nd measuring instrument 14 performs a test to detect the presence or absence of a disconnection of the wire 4. If a disconnection is detected, the winding job is immediately discontinued to restart the job from the beginning. While the device 15 measures the inductance in addition to detection of a disconnection in case no defective insulation nor disconnection is detected and the end 4b is supplied to a wire holding part 13 after the wire 4 is wound up to a level approximate to a prescribed number of turns. Then the remaining number of turns is calculated from the measured value of inductance, and the wire 4 is wound by an amount equal to the calculated number of turns to complete winding job.

Title: Casting form for pouring thermally curable premixed unshaped refractory material
Inventor: SAKURAI MASAAKI
IPC: C21B7/14
Filed: 1995-02-28
Abstract: PURPOSE: To stably obtain an executed material of high life and to simplify the execution by using a porous iron plate as the material of a form, and specifying the data regarding the plate. CONSTITUTION: A form 1 is formed of a porous plate 2 reinforced by retaining metallic material 4 as a reinforcing material, at one wall, and the remaining walls are formed of an iron frame 3. The diameter of the pores of the plate is limited to a range of 1 to 15mm. If the diameter of the pore is less than 1mm, clogging scarcely occurs, and at the time of heating, scattering of steam and gas is not smooth. The thickness of the plate is limited to a range of 0.3 to 10mm. If the thickness is less than 0.3mm, its strength is insufficient, while if the thickness exceeds 10mm, the weight of the frame becomes excessive, and the work becomes difficult. Thus, the physical properties of the executed material are improved, the executed time is shortened, the usability is increased to prolong the service life, and the execution cost is reduced.  Accordingly, industrially advantageous effect is obtained.
