Title: Lamp
Inventor: MIYASHITA HISASHI
IPC: H01J61/35
Filed: 1990-11-28
Abstract: PURPOSE:To change light emission colors conveniently and effectively by providing a dielectric multilayer film of specified optical thickness on the bulb surface of a lamp. CONSTITUTION:A trough of transmissivity 10-70% which has a width of the half of 100nm or below is provided near 590nm, and a multilayer film is formed as an interference film which consists of a high refractive index evaporation layer made of tantalum oxide, zirconium oxide, hafnium oxide or titanium oxide and a low refractive index evaporation layer made of silicon oxide, magnesium fluoride or aluminum oxide. As a result, light source colors can be changed without increasing the number of dielectric multilayer films fired on the surface of a quartz bulb for a halogen bulb or a HID lamp. Also, resulting efficiency drop can be minimized simply by changing the thickness of a dielectric for convenience in manufacturing.

Title: Power source circuit for telephone set
Inventor: NISHIO KOJI
IPC: H04M19/08
Filed: 1987-12-21
Abstract: PURPOSE:To easily add another power source circuit for backup by connecting a discharge prevention circuit between the connection point of a constant current circuit to a constant voltage circuit and an output terminal. CONSTITUTION:The discharge prevention circuit 29, for example, consisting of a diode is connected between the connection point 1d of the constant current circuit 21 to the constant voltage circuit 23 and the terminal 1c at an output side. The discharge prevention circuit 29 prevents the back flow of a current from the terminal 1c to the connection point 1d from occurring when an electronic switch 25 is closed by the drop of a voltage between a terminal 1a and a terminal 1b and the potential of the connection point 1d drops. Also, in the case of supplying a power source from another power source to a load connected to the terminal 1c, the back flow of the current from the another power source to the connection point 1d of the constant current circuit 21 to the constant voltage circuit 23 can be also prevented from occurring. In such a way, it is possible to easily add the power source for backup.

Title: Load module library management mechanism
Inventor: OSHIMA HIRONAGA
IPC: G06F9/06
Filed: 1994-12-27
Abstract: PURPOSE: To generalize the fragmentation in a load module library with generations produced by the differential management and to degenerate the file size. CONSTITUTION: When an execution request is given to a program execution part from a user space, a generation management mechanism 1 has an access to a medium 2 to produce the management information 1a and summarizes the essence of the information 1a to write it in a shared memory 3. When the requests are given from the user space for deletion of generations and degeneration of files, the mechanism 1 reads a load module library and generalize the fragmentation while assuring an atomic action. At the same time, an idle area is returned when no user of a releasable extent exists any more and after referring to the information 1a. Then the files of the medium 2 are degenerated. If the abnormality occurs during the processing, a standby server 4 works to restore the information 1a from the essence information stored in the memory 3 and carries on the processing.

Title: Focusing ion beam device
Inventor: NAGAMACHI SHINJI
IPC: H01L21/3065
Filed: 1994-12-27
Abstract: PURPOSE: To provide the title focused ion beam device capable of fine processing insulator with high precision. CONSTITUTION: The positive ion beam produced from ion source 1 is formed by capacitor lens 2, directed to a charge converter 3 and converted into a negative ion beam.

Title: Stabilizing dc power circuit
Inventor: KUDO KINJI
IPC: G05F1/56
Filed: 1988-12-22
Abstract: PURPOSE:To prevent the destruction of a 1st transistor TR by so securing a constitution that the output voltage drops when a short circuit state is pro duced between a DC output terminal and a common terminal and at the same time the current of the 1st TR is reduced. CONSTITUTION:In an overcurrent state, the base current of a 1st TR Q1 increases and a 2nd resistance R2 has its increased voltage drop together with a 5-th TR Q5 turned on respectively. Thus the base current of a 2nd TR Q2 is limited and a load current is also limited. When the output voltage is dropped for limit of the load current, a 4th TR Q4 is turned on and the base currents of the TR Q2 and a 3rd TR Q3 are reduced. At the same time, the base current and the collector current (load current) of the TR Q1 is also reduced. Thus it is possible to protect the drop and draw-in type overcurrents without detecting directly the load current.
