Patent JP-S62213404-A (JP)
Title: Power amplifier circuit
Inventor: KANEKO YOSHIAKI
IPC: H03F1/02
Filed: 1986-03-14
Abstract: PURPOSE:To obtain the maximum efficiency in the range without distortion substantially by providing a control circuit controlling a gate bias voltage in response to an output stage level to a transistor (TR) for power amplification. CONSTITUTION:A matching network 5 is provided to an output stage of a TR 1 for power amplification and the output level is detected by a level detection section 7 provided to the post-stage. When an input signal level at a terminal 2 is small, the output level of the TR 1 is also small and the detection output at the level detection section 7 is small. A control circuit section 8 controls the gate bias point of the TR 1 in response to the detection output so that the TR 1 has the maximum output level while keeping the state without distortion substantially. Since the control is executed in response to the input signal level, the maximum efficiency is obtained from the amplification operation of the TR 1 in the range without distortion substantially.

Title: Signal controller
Inventor: KAWABATA TATSUAKI
IPC: H02P29/00
Filed: 1980-04-25
Abstract: PURPOSE:To improve the control precision of a roller system by obtaining a stable controlled variable which never varies stepwise as the output signal obtained by adding signals of the 1st and 2nd signal generators together. CONSTITUTION:Signals sent out of signal generator 13 and 14 are inputted to CPU18. This CPU18, when adding output signals of generators 13 and 14 by receiving a timing signal from timing signal generator 15, adds a signal controlled variable, obtained by eliminating a bias component in the output signal of generator 14, and that of generator 13 together to store the sum in memory 19, and outputs an actual total corrected controlled variable via output part 15. Thus, a controlled variable which never varies stepwise is obtained as the actual total corrected quantity of each continuous stand, so that the control precision of the rolling system can be improved.

Title: Separator for low-temperature fuel cell and its manufacture
Inventor: FUKUI YASUSHI
IPC: H01M8/10
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To provide a metal separator for a low-temperature fuel cell with high acid resistance, high conductivity, and less generation of Joule heat caused by contact resistance. SOLUTION: This separator has a deposit layer 14 of SiC, B4 C, TiO2 , or the like formed on a stainless steel substrate 13 via a diffusion layer 15. The deposit layer 14 is formed, in such a way that a coating film in which the compound particles are dispersed is formed on the substrate surface, and heated in an non-oxidizing atmosphere of 300-1,100 deg.C to decompose and remove the coating film components. Prior to heat treatment, the stainless steel substrate 13 of which the coating film is formed may be rolled. Since the contact resistance of the separator is low, even when many cells are stacked, the generation of Joule heat which causes heat loss is suppressed, and the separator can be formed in a required shape by press forming, punching work, or the like.

Title: Warm water solenoid valve
Inventor: NAGURA HIROYUKI
IPC: F16K31/40
Filed: 1990-03-08
Abstract: PURPOSE:To hinder a pilot valve from deposit of foreign matters and prevent the valve from shortage in the stroke by flowing out the foreign matters, which deposit on the bottom surface of a spring accommodation hole provided in the upper part of a pilot valve, through the action of streaming water through a groove leading to the accommodation hole. CONSTITUTION:When a warm water solenoid valve 100 is opened, i.e. when a pilot valve 1 has moved up with current feeding to a solenoid 4, the water stagnating in the upper part of the valve 1 is actuated for streaming, so that water flow is generated from a cruciform groove 1c provided in the valve 1 as shown by arrow A, and thereby the foreign matters which are going to deposit on the bottom of an accommodation hole 1a will flow to outside of the valve 1. On the other hand, the foreign matters which are going to deposit on the oversurface of the valve 1 creep on the chamfer 1d of the top surface and flow to outside the valve 1. Thereby the valve 1 is hindered from depositing of foreign matters. If on the other hand deposited foreign matters cause insufficient stroke of the valve 1, the lift of valve 1 becomes small even with current feeding to the solenoid 4, and water stream to a pilot hole 10 will lessen. Accordingly a main valve 7 remains shutting the main port 11.

Title: Method of monitoring fan rotation
Inventor: GOTO YUICHI
IPC: G06F1/20
Filed: 1991-03-20
Abstract: PURPOSE:To monitor rotation of many fans with a small number of work regions by grouping a plurality of fans and by not only monitoring them in succession group by group, but also using work regions in succession among groups according to monitoring. CONSTITUTION:A monitor controller 11 uses a microprocessor to count changeovers of rotation pulses outputted from a plurality of cooling fans 10-1-10-6 installed in an information processing system apparatus, thereby monitoring whether the fans 10-1-10-6 are rotating normally. This plurality of fans 10-1-10-6 are grouped one by one or more by more. The monitor controller 11 simultaneously monitors only fans belonging to one group and uses a count work region 12 to check the number of revolution of fans of this group: if no abnormality is found, the controller changes over fan groups to be monitored every predetermined time. This way makes the count work region 12 shared by groups.

Further, the device 50 converts the signal from the sensor 7 to saturated pressure to measured temp. By this method, leak quantity can be measured accurately.

Title: Rubber-based adhesive plaster
Inventor: SAWAGUCHI MAREYOSHI
IPC: A61K9/70
Filed: 1983-03-31
Abstract: PURPOSE:To prepare a pharmaceutical adhesive plaster having suppressed decomposition of the drug component and improved stability, by compounding a hydrated organic solvent extract of rosemary, delta-tocopherol and ascorbyl stearate to a plaster base composed of a rubber-based adhesive substance. CONSTITUTION:The objective plaster is obtained by compounding a plaster base composed of a rubber-based adhesive substance (e.g. natural rubber) with a hydrated organic solvent extract of rosemary (e.g. ethanol extract of rosemary), delta-tocopherol and ascorbyl stearate. The application of a drug component to the skin is carried out usually by the use of a pharmaceutical adhesive plaster obtained e.g. by compounding the drug component to a plaster composed of an adhesive substance. When a pharmaceutical preparation obtained by compounding a drug, especially a compound containing phenolic OH-group or an amine compound to a plaster composed of a rubber-based adhesive substance is stored for a long period, the remedying effect is remarkably decreased by the decomposition and dissipation of the drug component. The decomposition of the drug can be suppressed by compounding the above extract, etc. to the plaster.
