Patent JP-S5613734-A (JP)
Title: Gallium arsenide semiconductor device
Inventor: TAKEUCHI MASAMI
IPC: H01L21/265
Filed: 1979-07-16
Abstract: PURPOSE:To improve the degrees of integration of semiconductor elements by a method wherein O ions and As ions are twice injected to a semiconductor region on the surface of a GaAs substrate and stable high resistance layers are obtained. CONSTITUTION:An N-epitaxial layer 5 on a semi-insulating GaAs substrate 4 is coated with a mask 6, and O ions are irradiated, and let reach to the substrate 4. O ions are distrubuted into GaAs, function as traps, prevent the movement of carriers, and form high resistance layers 7 at the both sides of an active layer 8. However, As on the surface of the N-layer 5 disperses outside the substrare during heat treatment after injecting O ions, O2 enters portions where As escapes and serves as donars, and a conductive layer is easy to be formed on the surface of an insulating layer after heat treatment. As ions are further injected, and the quantity of injection is optimized in response to heat treatment time. When injection is excessive, Ga cavities are formed, and electric characteristics are remarkably deteriorated. The normal quantity of injection may be 10<13>-15<15>cm<-2>. After ions are injected twice, the whole is annealed in H2 or Ar. This constitution can accurately decide a region of the active layer, can contract the separating distance of elements, and improves yield and the degree of integration.

Title: Measuring method of working time
Inventor: MATSUOKA SHIGENORI
IPC: G07C3/02
Filed: 1980-07-01
Abstract: PURPOSE:To firmly accumulate the working time of a equipment which operates intermittently by controlling interruption to a computer with the use of rising and lowering of an operation signal and a working signal which become high level while operating the equipment. CONSTITUTION:In case when dust incineration systems are operated, a digital signal DI becomes high level and at the same time a rising signal R and a lowering signal F of a signal DI are started to interrupt. When the signals are finished, interruption to the computer which controls other systems is started. The working time of dust incineration systems can be counted by counting of a clock while interrupting. While the signal DI provides high level if a computer releases the interruption to control other systems and after the processing is finished and when interruption is started again, if the signal DI provides continuously high level, this signal DI becomes a starting signal for interruption after the signal DI is started. Therefore, misjudgement to set the signal F as the starting signal for interruption can not be generated and the accumulation of working time of an equipment which works intermittently can firmly be performed.

Title: High speed synchronous pll oscillator
Inventor: YANASE AKINORI
IPC: H03L7/10
Filed: 1988-04-12
Abstract: PURPOSE:To allow a control voltage required for a VCO just after the changeover of the number of frequency divisions of a variable frequency divider and to minimize the deviation of an oscillated frequency of the VCO with respect to the change in the oscillated frequency by charging the control voltage of the VCO to one of 1st and 2nd capacitors in response to the number of frequency divisions after the changeover, so as to switch the frequency division ratio of the variable frequency divider. CONSTITUTION:The 1st capacitor 8a is connected to a control loop via a switch 9a before a frequency division ratio designating device 5 is subject to change operation. When a new data is sent to a variable frequency divider 2 by the frequency division ratio designating device 5, the variable frequency divider 2 starts frequency division newly. A switching trigger signal 11 is sent to a switch controller 10 together with the data in this case to change over switches 9a, 9b by using switching signals 12a, 12b. Thus, the 2nd capacitor 8b corresponding to the data is connected to the control loop via the switch 9b to set the controlled voltage of the VCO 1 momentarily and the time required for synchronization is reduced.

Abstract: PURPOSE:To avoid the useless exchange of a process cartridge by dividing a process apparatus into two groups whose use frequencies are different and making them singly attachable and detachable with respect to a device main body as first and second cartridges. CONSTITUTION:When the process cartridge 14 consisting of the first and the second cartridges 14A and 14B is detached from the device main body 1, an opening and closing member 30 on the device main body 1 side is needed to be opened. In such a case, the second cartridge 14B is separated from the first cartridge 14A by interlocking with the opening action of the member 30 so that the first and the second cartridges 14A and 14B can be singly taken out from the device main body 1. Then, when the member 30 is closed after the cartridges 14A and 14B are properly exchanged to new ones the second cartridge 14B is closely brought into contact with the first cartridge 14A by interlocking with the closing action thereof. Then, a state that an image can be formed is obtained. Thus, the large uselessness does not occur when the process cartridge is exchanged.

IPC: A61K8/00
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a cosmetic material manifesting an effective antibacterial effect, not only not showing a primary irritation or a sensitization to a skin, but also not giving an uncomfortable feeling such as a piercing pain, an irritating feeling and a prickling feeling on using the cosmetic material. SOLUTION: This antibacterial low irritating cosmetic material contains 2-phenoxyethanol, and one kind, or two or more kinds selected from extracts of plants having an antibacterial activity to begin with a ginkgo, a low striped bamboo (Sasa albo-marginata) and Asarum sieboldi. The amounts of blending of 2-phenoxyethanol and the plant extracts are suitably 0.05-1.0wt.% and 0.01-20.0wt.% respectively. Since the antibacterial activity is synergistically enhanced by the simultaneous utilization of the plant extracts, a sufficient antibacterial effect is exhibited by blending approximately 0.2wt.% 2- phenoxyethanol, the irritating property to a skin or uncomfortable feeling on using can be relieved.
