Title: Method and device for stack cutting of strip steel
Inventor: SASAKI TSUYOSHI
IPC: B23D19/00
Filed: 1989-06-13
Abstract: PURPOSE:To cut a thin strip steel and also a soft strip steel with a high efficiency without any burr on the cutting face by cutting a strip steel with its stacking at least two sheets, and arranging a thin steel strip or soft steel strip at the round edge side coming into contact with a steel strip chip and a thick steel strip or hard steel strip at the round edge side coming into contact with a product at the side trimming time by a pair of the upper and lower rotary round edges. CONSTITUTION:An upper side rotary round edge 1a is brought into contact with a steel strip chip 2c and a lower side rotary round edge 1b is brought into contact with a steel strip product 2d and cutting is executed, when two stacking steel strips are subjected to side trimming by a pair of the upper and lower rotary round edges, so a thin steel strip 2a is stacked on a thick steel strip 2b. When the steel strip-stacked like this are subjected to trimming, a pretty cutting face having no burr, etc., is formed because of the thin steel strip 2a being supported on the lower side thin steel strip 2b of large stiffness and the lower side thick steel strip 2b can obtain the cutting face of a conventional type. Trimming can be executed with high efficiency by increasing the stiffness of the whole body with the stacking at least two sheets of thin and thick steel strips, soft and hard steel strips or thin and hard steel strips and by abutting the rotary round edge on the thin or soft strip steel at the steel strip chip side.

Title: Semiconductor laser and manufacture thereof
Inventor: FUKUZAWA TADASHI
IPC: H01S5/16
Filed: 1988-06-21
Abstract: PURPOSE:To obtain a laser having a high catastrophic optical damage(COD) level by forming an end face to which a band gap wider than the composition of an active layer, into which impurity ions are not implanted, is shaped. CONSTITUTION:A clad layer 4, a multiple quantum well type laser active layer 6 having superlattice structure, a clad layer 7 and a cap layer 9 are grown successively onto a substrate 3 by using an MBE method, thus forming laser structure. Si ions 21 are implanted. A region 17, into which Si is implanted in high concentration, in the multiple quantum well laser active layer 6 is shaped besides a region 12 into which Si is implanted. Since an impurity element implanted is activated and changed into a mixed crystal, an interface level is elevated and a band gap is scaled up in the window region of the active layer 6 to which an end face is formed, beams are hardly absorbed, thus displaying the action of the reduction of heat generation.

Title: Current resonance type converter
Inventor: HANAWAKA MASUO
IPC: H02M3/335
Filed: 1989-06-14
Abstract: PURPOSE:To control output voltage to a fixed value in a current resonance type converter in a discontinuous mode by changing an inductance value of a variable inductor with the control current to cause resonance frequency variations. CONSTITUTION:When input voltage Vin is reduced, the resonance frequency is reduced due to the increase of inductance of a variable inductor 9 and it is stabilized at a point when the output voltage before the fluctuation becomes equal to the output voltage after the fluctuation. By controlling the variable inductance in this way, the output voltage can be kept constant against the input fluctuation. In a physical circuit the output voltage changes against the load fluctuation. It is, however, far less than the influence of input fluctuation and by changing the resonance frequency and controlling the ratio of input voltage to output one, it can be well matched off.

Title: Surface profiling device
Inventor: HOSOI TOSHIAKI
IPC: B23Q33/00
Filed: 1980-10-27
Abstract: PURPOSE: To enable the surface profiling work where the edge will never gnaw by performing the profiling contact such that the stylus is advanced relatively by predetermined amount against the tool.  
     CONSTITUTION: Upon contact of a stylus (S) against the horizontal face of a model, a spindle 6 will lift against a coupling mechanism 16 while a differential transformer 41 will produce the positive signal and a motor 31 will rotate in the normal direction (H) untill the signal is disappeared thus to rotate an arm 11b to the right together with a light blocking board 50a. Consequently the stylus (S) will be shifted to the right against the edge to reduce the light receiving area of an element 52b while to increase the light receiving area of an element 52d. The simulation speeds in the down direction and X-direction are controlled respectively by the light receiving areas of the elements 52b, 52d. Since the stylus is advanced by the predetermined amount from the edge, and the convex/concave of the model can be sensed quickly thereby the edge can perform the simulation work.

Title: Antiferroelectric liquid crystal display element
Inventor: TANAKA TOMIO
IPC: G02F1/1337
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To make it possible to distinctly display gradation by enclosing antiferroelectric liquid crystals which form many intermediate states by changing part of the liquid crystal molecules in one orientation state to another orientation state according to impressed voltages. SOLUTION: The electrode forming surfaces of a lower substrate 11 and an upper substrate 12 are respectively provided with oriented films 18, 19. These oriented films 18, 19 are horizontally oriented films consisting of org. high- polymer compds., such as polyimide, and the opposite surfaces are subjected to orientation treatments by rubbing in the same direction. The antiferroelectric liquid crystal element has the first and second orientation states at the molecule level. The orientation state of the liquid crystal molecules changes from the first or second orientation state to the second or first orientation state, respectively, according to the impressed voltages. The partial regions varying in the orientation states are, therefore, generated in a plurality in the wavelengths of the light of a visible region.  The optical characteristics are consequently averaged and the many intermediate states between the ferroelectric layer and the antiferroelectric layer are formed. The distinct gradation display is thus made possible by using such intermediate states.

Title: Luminous radiation electron tube
Inventor: UETSUKI TADAO
IPC: H01J61/95
Filed: 1985-07-10
Abstract: PURPOSE:To increase the luminous efficiency of a luminous radiation electron tube and make a current limiter unnecessary by applying a voltage for ionizing luminous radiation gas across a cathode and an anode and applying a voltage optimum for exciting the luminous radiation gas across another cathode and another anode so as to separate electrons which induce ionization from those which induce excitation. CONSTITUTION:A voltage (+ several volts) which sufficiently ionizes mercury atoms is applied across a cathode 2a and an anode 3a. And, a voltage (5-9 eV) optimum for exciting mercury is applied across a cathode 2b and an anode 3b. Electrons discharged from the cathode 2a are accelerated by the anode 3a before striking against mercury atoms to ionize them thereby electrically neutralizing the space and producing a weakly-ionized plasma 9. Neutralization of the space enables an electron beam having an energy (5-9 eV) optimum for excitation of mercury to travel from the cathode 2b to the anode 3b and become incident upon the space 9.

IPC: G06T11/00
Filed: 1989-06-14
Abstract: PURPOSE: To make the construction of a graphic model by means of dimensional correction by storing the constraints relating to input keys or commands. CONSTITUTION: In the object input mode, the user uses a creative key 27 to input the basic form of mechanical component, etc. The physical dimensions of an object can be input as invariable size, variable size, and flexible size. A constraint, which is triggered by pushing one of the keys of a subgroup 27b being accompanied by constraints, is also recorded. A program memory 29 contains instructions for storing constraints relating to commands, and instructions for extracting the constraints to construct a graphic model. Input data is stored in the dimensional memory 37 of an object memory 36 and an key memory 38. In the correction mode, data is extracted from the object memory 36. If the dimensions of a graphic model are of the variable type, an actual, size that realizes a transformed object is input to replace the variable size.  Further, the constraints are extracted to generate an actual transformed object. In addition, if the value of the size was input as a flexible size to be defined by the already defined two geometrical positions, since the numeral of the size can be obtained by referring to the geometrical positions in the correction mode, the user need not input the numeral of the size.

IPC: B21D26/08
Filed: 1977-12-20
Abstract: PURPOSE: To prevent the generation of crack while working the explosive expansion of the pipe, by arranging the reinforcing member at the position of pipe corresponding to the end part of the explosive-filling-portion, and by restraining the deformation due to the expansion of the pipe at this position, in the explosive-pipe-expanding method.  
     CONSTITUTION: When the pipe 2 is to be fitted to the tube plate 4 by the explosion of the explosive 1, the reinforcing ring 5 is fitted so as to cover the position of pipe corresponding to the end part of the explosive 1. Hereby, the deformation of the pipe 2 at the position of the ring 5 is restrained while the explosive expansion of the pipe 2 is worked, on purpose to prevent the crack in the expanded pipe 2. Besides, the smaller the clearance between the ring 5 and the pipe 2 is, the larger the effect is, however, this clearance is generally preferable to be settled under 3% of the outside diameter of the pipe 2. By carrying out the explosive expansion of the pipe according to this method, the expansion and pressure welding of the pipe can be performed without generating the crack in the pipe.
