Title: Structure material of light weight for movable member
Inventor: ASAI KOUICHI
IPC: F16S1/04
Filed: 1989-12-14
Abstract: PURPOSE:To obtain a light weight structural material for a movable member easy to obtain stiffness and working accuracy and having less effects of a thermal deformation as well, by providing 1st and 2nd base plates consisting of steel thin plates and opposed each other at a small interval and a medium plates linked by welding on the both base plates therebetween. CONSTITUTION:X and Y axial slides 16, 38 are taken as of light structural materials and the structure is the same. The slide 16 is made with the upper plates 66, 68, 70 of a 1st base plate, the lower plate 72 of a 2nd base plate, a U shaped side plate 74, a rectangular side plate 76 and L shaped side plate 77 being fitted to the connection grid 64 where a U shaped 1st medium plate 60 and rectangular large and small 2nd medium plates 62, 63 of two kinds are mutually engaged. These plates 60, 62, 66, 68, 70, 72, 74, 76, 77 are composed of steel-made thin plates. The slides 16, 38 have a high rigidity in spite of a light weight because of steel-made thin plates being assembled and the machining is easy compared to those made of aluminum, so a high accuracy can be obtained. Also, no distortion due to the difference in the thermal deformations from the same steel made peripheral member is generated.

Title: Semiconductor laser device
Inventor: KAGAWA HITOSHI
IPC: H01S5/00
Filed: 1990-11-26
Abstract: PURPOSE:To obtain a semiconductor laser device whose threshold current is small, whose efficiency is high and whose life is long by a method wherein the resistivity in a layer part near an active layer of a second clad layer is made large as compared with the resistivity of a layer part which is distant from the active layer. CONSTITUTION:The resistivity of a first-layer part 61 close to an active layer 4 of a second clad layer 5 is made higher than the resistivity rho2 of a second- layer part 62 which is distant from the active layer 4. That is to say, the first- layer part 61 and the second-layer part 62 in the second clad layer 5 are formed so as to become rho1>rho2. In this case, a leakage current component Io in the total electric current It which has been injected through a path which has been limited to a width W at the bottom part of a ridge 51 is influenced especially by the resistivity rho1 and by the thickness d of the first-layer part 61 in the second clad layer 5. Consequently, the leakage current component Io can be suppressed to be small. Thereby, it is possible to obtain a semiconductor laser element which suppresses an increase in an element resistance to be small and whose leakage current component Io is small.

Abstract: PURPOSE:To reduce the waste of the time between color developing paper and the electric power consumption of a heater in the time when heat fixing is not executed by detecting the intervals when the color developing paper is transported at the time of heat fixing and controlling the heater output or the transporting speed of a heat fixing section. CONSTITUTION:This device has means 10, 11 which detect the information corresponding to the intervals of the color developing medium 2 on the upper stream side of the heat fixing section 5 in the transporting direction of the medium 2 and means for controlling the output of the heater 7 of the heat fixing section 5 or the relative transporting speed of the medium 2 with the heat fixing section 5. Namely, the information on the intervals of the paper 2 carried into the heat fixing section 5, i.e., on whether the paper is continuous or discontinuous is detected and the heater output or the relative transporting speed of the medium 2 with the heat fixing section 5 is controlled according to this information. The effective utilization of the heater capacity and the time for the intervals between the color developing paper is effectively utilized. The wasteful electric power consumption of the heater of the heat fixing section is thus reduced.

Title: Circuit and method for switch interruption processing
Inventor: INAMORI SHINICHI
IPC: G06F9/46
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent the influence of the chattering of a mechanical switch and external noise by performing a specific interruption process when the interval between edges of an interruption signal is in the range of a predetermined time. SOLUTION: When the mechanical switch 30 is pressed and the interruption signal varies from High to Low, a CPU 10 detects a trailing edge of the interruption signal (INT) and starts a timer. When the interruption signal is inputted for the second time, the change of the switch 30 is caused by misoperation or chattering and ignored on condition that the clocking time of the timer is <=0.2 second. The timer is restarted 0.2 second later. When the operator puts the hand away from the switch 30, the interruption signal has an edge changing from Low to High. An interruption processing program turns ON the function to be executed by the switch depression when the clocking result of the timer is <=3 seconds.
