Title: Operating system for system resources
Inventor: FUKUNAGA TADASHI
IPC: G06F9/46
Filed: 1986-03-04
Abstract: PURPOSE:To control and set automatically the working environment of an OS in response to the operating situation of the OS, by defining the larger one of both values obtained by multiplying the maximum recorded value by a prescribed margin factor set previously and the value set on a resources control table as the allocated value of the system resources to the OS. CONSTITUTION:A start means 2 first refers to the log data 5 when an operating system OS1 is started and checks the maximum value so far used for each of various system resources 10 to multiply this maximum application value by a margin factor set previously. Then the value thus obtained is compared with the set value on a resources control table 3 and the larger one of both values is defined as the application area of the OS1. Thus a new working program, for example, works and the work area of the OS1 is increased. While the margin of the system resources allocated to the OS1 is reduced. Thus the resources 10 are allocated to the OS1 in consideration of situations despite such fluctuations of the system operating state. In such a way such an unexpected case where the system working is stopped due to insufficiency of resources can be prevented.

Title: Cast material for metal product having smooth surface and manufacture thereof
Inventor: SUGIMOTO KIMITOSHI
IPC: B23P9/04
Filed: 1988-02-29
Abstract: PURPOSE:To reduce the working quantity and obtain a smooth surface of a worked surface onto which the vacant holes in material are hardly exposed, by allowing the vacant holes generated during the coagulation process are collapsed by the plastic working in the surface layer of a cast material including the smooth surface of a product. CONSTITUTION:When the surface layer 8 of a cast member is heated at a temperature permitting easy plastic deformation, and shot peening is applied onto the surface layer 8 simultaneously or continuously by a steel ball group, the metal part around a vacant hole is hot-plastic deformed by the impact force of the steel balls 1 which collide incessantly onto the surface of the member, not only in case of a flat surface 9 but in case of a curved surface, and the pin hole 2 in the surface layer 8 and the vacant hole of a shrinkage cavity can be efficiently collapsed and press-attached. Therefore, a machining allowance part is set inside the surface layer 8, and even if this allowance is removed by machining, no recessed part caused by the vacant hole is generated. Further, a metal product having a necessary smooth surface can be obtained with a little working quantity.

Title: Waveguide type optical isolator
Inventor: KASHIMURA SEIICHI
IPC: G02B6/122
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a waveguide type optical isolator which has a small increase rate of insertion loss even when the number of waveguides which are branched and connected is increased. SOLUTION: Light which is reflected by a connector or an optical component of a transmission line to return after being emitted from a light source has its mode distribution shifted to radially outside a curve while propagated reversely in a curved waveguide. The light in a linear waveguide 2-3 branching tangentially halfway off the curved waveguide 3 is propagated to a linear waveguide 2-3 radially outside the curve. In this case, a linear waveguide 2-2 on a branch connection side is wider, so the light moves to and is propagated in the linear waveguide 2-3 with low loss. The light from the light source which is propagated forward in the curved waveguide 3, on the other hand, decreases in the spread width of the mode since the curved waveguide 3 is narrower at the branch part and is able to pass nearly without being affected by loss due to radiation.  Therefore, even when the number of waveguides which are branched and connected is increased, the increase rate of the insertion loss never becomes large.

Filed: 1994-03-18
Abstract: PURPOSE:To prevent the aggregation of a film material when an org. thin film is formed and to form the highly uniform org. thin film at the gas/water- interface. CONSTITUTION:An org. thin film is formed by the Langmuir-Blodgett's method.

Abstract: PURPOSE:Refrigerant vapor remaining after desorption is completed is adsorbed in another absorbing tower prior to a changing-over of adsorption desorption and each of the adsorbing or desorbing progressing in each of the adsorptive towers is further continued by a method wherein two adsorptive towers are connected directly by a pipe and a valve is arranged in the pipe. CONSTITUTION:Adsorptive towers 11 and 11' are connected to each other by arranging a pipe 10 having a valve V5 in the midway of the pipes. When an adsorptive or desorption stage is completed, the adsorptive tower 11' is kept at its high pressure stage with the desorbed refrigerant vapor and the adsorptive tower 11 adsorbs the refrigerant and is kept at a low pressure state. Accordingly, as the valve V5 is opened, the refrigerant vapor passes through the pipe 10, moves from the adsorbing tower 11' to the adsorbing tower 11 through the piping 10 and then the pressures within the adsorptive towers 11 and 11' are balanced. During this period, cooling water and heat source heating medium flow in both thermal conducting pipes 13 and 13', a solid adsorbent S is cooled in the adsorptive tower 11' so as to promote adsorption, movement of the refrigerant vapor is assisted and then each of the adsorptive or desorb stage is further advanced in the adsorbing towers 11 and 11'.

Abstract: PURPOSE: To improve braking efficiency and mud intrusion prevention by providing a guide member and wind collection member in the inside of the vehicle and providing an introducing member surrounding the rotor stem and having a downwardly convex arcular sectional profile.  
     CONSTITUTION: At the time of running, the head wind flows from the end of a wind correction member 41 toward a guide member 43, and mud strikes the guide member 43 due to its momentum and is discharged to the outside from a lower portion where the guide member 43 does not extend. The inflowing air is led through a communication hole in the wind collection member 41, a communication hole in a guide member 51 and a curl section 55 to enter a cooling air passage hole 21a in a disc rotor 21 and prevent the reduction of the brake force. The mud in air flowing to an introducing member downwardly flows along the curl section 55, which has an arcular sectional profile with the radius of curvature reducing toward the bottom. Thus, the spattering of mud on bearings 15 and 16 is prevented, braking effect and cooling effect can be improved.

Abstract: PURPOSE:To enable measurement at a desired angle of incidence without effect of a reflection mirror, by adjusting a measuring light so that after reflected with first and second reflection mirrors, it travels with the optical axis thereof passing through the center point of the surface of a sample on a sample base and further reflected with third and fourth reflection mirrors to move along the original optical axis. CONSTITUTION:When first and fourth reflection mirrors M1 and M4 inserted into a measuring optical path are positioned on an optical axis O1, a measuring light is changed in the optical path with the reflection mirror M1 and reflected with the second fourth reflection mirrors M2-M4 to return to the original optical axis O1 again. With such an arrangement, spectral reflection characteristic by reflection with all the reflection mirrors is determined. Then, a sample S is so arranged that the surface thereof reaches a position O of intersection between the optical axes O3 and O1 and the reflection mirrors M3 and M4 are replaced with reflection mirrors M3' and M4'. Consequently, the measuring light is made incident into the sample S at an angle theta of incidence to be reflected and further reflected with the reflection mirrors M3' and M4' to return to the original optical axis O1. Thus, comprehensive spectral reflection characteristic is measured from spectral reflection characteristic when light is incident into the sample S at an angle theta of incidence and that obtained by reflection from all the reflection mirrors.
