IPC: B23Q11/10
Filed: 1979-12-07
Abstract: PURPOSE:To prevent the clogging by chips and protect the machined thin groove partition walls of a magnetic head frame from being deformed by blowing out cutting oil from the inside of an arbor when machining plural grooves at fine intervals. CONSTITUTION:Cutting oil supplied from a feed pipe 11 to the inside of an arbor 7 when machining wide grooves 3 is blown out from blow-out grooves 14 towards the side faces of cutters 9 via cutting oil feed holes 12 and distributing grooves 13 and flows off chips which may clog between the cutters.

Filed: 1991-06-28
Abstract: PURPOSE:To apply a conventional method to a measuring sample where the cycle period of a stimulus is longer than the reciprocal of twice the maximum frequency fmax for an interferogram signal to have. CONSTITUTION:The reaction state of a measuring object to display repeatedly the same response o a stimulus is measured; by giving repeatedly a stimulus with a period longer than the reacting period of a sample 3 by a stimulus generator 4, obtaining an interferogram, to a fixed delay time from the stimulus, from the output of a detector 6 to use a rapid scan interferometer 2, and obtaining a spectrum by Fourier transform.

Title: Phototransistor
Inventor: TAKAMIYA SABUROU
IPC: H01L31/10
Filed: 1980-11-08
Abstract: PURPOSE:To suppress a dark current in a phototransistor by increasing the forbidden band-width of emitter and base layers larger than that of a collector layer. CONSTITUTION:An emitter 11 is formed of n type AlxGa1-xAs, a bsse 21 is formed of p type AlyGa1-yAs, a collector 31 is formed of n type GaAs, a substrate 51 is formed of n type GaAs, and a depletion layer 41 extends to the region 31. Since it is formed of a material having forbidden band width larger than the collector 31 at the emitter 11 and base 21, and the amplifying region has large forbidden band with as compared with the photoelectric conversion region in the phototransistor. Since the thermal excitation of electrons and holes is small in the region having large forbidden band-width, a dark current generated in the amplifying region can be suppressed to small degree to be ignored as compared with the unavoidable dark current generated in the photoelectric conversion region in the transistor.

Title: Manufacture of positive-characteristic thermistor heating element
Inventor: HORI MAKOTO
IPC: H05B3/14
Filed: 1990-06-15
Abstract: PURPOSE:To manufacture a positive-characteristic thermistor heating element with excellent durability and high reliability by hardening a thermosetting adhesive at a temperature higher than the operating temperature of the heating element. CONSTITUTION:An adhesive 6 is hardened at a temperature higher than the operating temperature 200 deg.C of a heating element 1 to manufacture the heating element 1. The heating element 1 is invariably used at the temperature lower than the hardening temperature of the adhesive 6, thus the adhesive 6 is not expanded while the heating element 1 is in use than when the adhesive 6 is hardened. The defective conduct due to the thermal expansion of the adhesive 6 as experienced in the past can be prevented. Since the operating temperature of the heating element 1 is lower than the hardening temperature of the adhesive 6, a shrinking force is applied to the adhesive 6 while the heating element 1 is in use, the contact pressure between a thermistor 2 and a metal heating element 3 is generated, thus the electric connection between the conducting electrode 5 of the thermistor 2 and a metal plate 3b can be surely performed.

Title: Speed alarm for vehicle
Inventor: MISAKI MASAMI
IPC: G01P1/12
Filed: 1981-10-06
Abstract: PURPOSE:To enable use of a running speed as revolution data and management data after a running by counting and recording it each time the speed exceeds the set value as long as it continues for a certain time. CONSTITUTION:Before the running speed meets the set value by a reference speed setting circuit 2, no output is produced at a comparator circuit 3 and hence, an alarm indication circuit 5 and a counter 8 both fail to work. When the speed during the running exceeds the values set by the reference speed setting circuit 2, an output is produced at the comparator circuit 3 and an oscillation circuit 4 works at a fixed cycle to have an alarm indication circuit 5 giving a warning. On the other hand, unless said running time meets the predetermined unit time with a time setting circuit 7, only the warning continues. As soon as it exceeds the unit time, a switching circuit 6 works by a signal sent from the time setting circuit 7 at each unit time to trigger the counting with a counter 8. In this invention, when the running speed exceeds the set value continuously, the counter 8 performs the counting repeatedly at each unit time.

IPC: B23Q5/44
Filed: 1994-06-17
Abstract: PURPOSE:To prevent transmission of abnormal torque caused by the movement of a screw, to a mobile member and deformation of the same by providing a parallel spring holder for fitting and fixing a feed screw and a female screw together in their center parts. CONSTITUTION:A parallel spring holder 5 is composed of a female screw holding part 5A for fitting and fixing a female screw at its center part thereof, and parallel springs 5B connecting between the holding part 5A and a mobile member holding part 5C. When a motor is driven so as to rotate a male screw 4, the female screw 3 is moved, and accordingly, power is transmitted to the female screw holding part 5A, the parallel springs 5B and the mobile member holding part 5C so that a mobile member is moved left and right. At this stage, the parallel springs 5B absorb eccentricity between the male screw 4 and the female screw 4, and a displacement caused by a curve of the male screw 4. Further, an auxiliary guide 6 absorbs abnormal torque exerted on the male screw 4 together with the above displacement. Therefore, it is possible to greatly enhance the accuracy of movement of the mobile member 1.

Abstract: PROBLEM TO BE SOLVED: To obtain a pigment composition hardly causing the shortage of print density or the turbulence of dot shape and capable of excellently dispersing pigment in a toner by kneading a pigment and a resin and dissolving, then freeze-pulverizing them and dispersing in a non-aqueous solvent. SOLUTION: This pigment composition is produced by freeze-pulverizing after kneading the pigment and the resin and dissolving and dispersing in the nonaqueous solvent. First, the pigment and the resin are kneaded. At this time, it is preferable that the resin is pulverized and the coarse particles are removed previously. For example, the resultant kneaded material is sufficiently cooled with solid carbon dioxide or liquid nitrogen, then is freeze-pulverized into <=1000μm, preferably <=500μm by a pulverizer. Next, the pulverized material is dissolved and dispersed in the nonaqueous solvent. The purpose of the pulverization is to crack and pulverize the hardened granule of the resin or the undispersed lump of the pigment produced in kneading and to facilitate the dissolution and the dispersion in the nonaqueous solvent by finely powdering the whole kneaded material.
