Abstract: PURPOSE:A thallium activated alkali halide fluorescent substance which has a specific composition, shows stimulating emission of high luminance and a short emission life when excited with stimulation. CONSTITUTION:The thallium activated alkali halide fluorescent substance shown by the general formula MX: aTl [M is Na, K, Rb or Cs; X is Cl, Br or I (X is I when M is Na and X is Br or I when M is K); a is in 0<a<=0.2 (preferably 10<-6=a<=10<-2>)]. The fluorescent substance is obtained by packing a fluorescent substance raw material mixture to a heat-resistant container such as quartz crucible, alumina crucible, etc., and calcining the mixture by an electric furnace preferably in a neutral or oxidizing atmosphere preferably at 400-1,000 deg.C for 0.2-10hr.

Title: Line connecting system in channel multiplex
Inventor: KOGA TAKAMASA
IPC: G06F13/00
Filed: 1979-05-02
Abstract: PURPOSE:To produce the data path efficiently, by checking the state of line of the respective channel and the state of the controller at line connection. CONSTITUTION:The data transmission channel control SVC station transmits the data to the remote station RS1 and checks whether or not this data is correctly received at the RS1 station and returned to SVC again. In case of the process input and output stations PRS1-PRSn having the process input and output channel controllers P10C1-P10Cn, if the flag is absent in the status in the return data, the same processing is made to the next RS2. If the flag is present, data is transmitted to P10C1 after being selected to the process input and output channel. P10C1 checks this data and returns the answer to SVC when normal. If no response, P10C1 is disconnected and the processing of the next RSn is given.

Title: Belt slip detecting device
Inventor: IDETO JUNJI
IPC: F16H7/00
Filed: 1986-03-11
Abstract: PURPOSE:To avoid the interference between members, by not opening and closing suction and exhaust valves when belt slip is detected. CONSTITUTION:When a signal is fed from a crank shaft angle detecting means 1, a phase difference detecting means 3 starts to operate. While a crank shaft is rotated at a predetermined angle from this timing, the phase difference detecting means 3 determines whether or not a signal is fed from a cam shaft angle detecting means 2. If it is determined that the signal is absent, a valve lift variable means 5 is controlled to reduce an oil pressure in a valve zero-rush mechanism 4. As a result, a force from a cam shaft is not transmitted to suction and exhaust valves, thus stopping the opening/closing operation of the suction and exhaust valves. A timing of detecting the slippage of a phase difference is selected to a specific operational timing of the suction and exhaust valves. Therefore, prior to the occurrence of any trouble due to the belt slip, the valve lift variable means 5 and the valve zero-rush mechanism 4 are operated to avoid the interference between members.

Title: Power source control system
Inventor: YAMAMOTO TAKEAKI
IPC: G06F1/26
Filed: 1988-03-09
Abstract: PURPOSE:To control a power source system economically with high working ratio, by turning off the power source for the entire system immediately after occurrence of fault. CONSTITUTION:When a fault detecting means 12c for a slave power source equipment 12 detects droppage of AC input, a fault type signal generating means 12f provides a fault type signal to a power source ON/OFF command means 11e for a master power source equipment 11 so as to interrupt output from its power source unit 12a. A fault occurrence signal means 12e provides a fault occurrence signal to the power source ON/OFF command means 11e before the power source unit 12a is turned OFF. Upon reception of the fault occurrence signal and the fault type signal, the master power source equipment 11 detects the occurrence of a fault and turns off the output of its power source unit 11a through the power source ON/OFF command means 11e while simultaneously commands respective slave power source equipments 13 to turn off the power sources. The slave power source equipment 13 turns off the output from the power source unit 13a based on the command. When any of devices in the power source system detects a fault, power is interrupted for the entire power source system.

Title: Semiconductor device
Inventor: KONDO YOJI
IPC: H01L23/50
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To restrain generation of solder crack on a soldering portion between an outer lead terminal and a printed board, and thus to improve reliability, by providing a curved portion having a spring action at an intermediate position of the outer lead, and providing a certain degree of freedom in elasticity of the outer lead. SOLUTION: In order to provide a certain degree of freedom in elasticity of an outer lead terminal 12b, the outer lead terminal 12b is largely curved to above a semiconductor device at a part slightly outward from an edge of a resin, so as to have a spring action. In the case where this semiconductor device is mounted on a printed board, if convex warping is generated on the semiconductor device, the distance between facing metal patterns for soldering outer lead terminals 52, 53 to a printed board 54 is elongated, and the outer lead terminals 52, 53 are pulled outward and below the semiconductor device. However, the spring action of a curved portion 52a of the outer lead absorbs the tensile stress. Thus, generation of crack in the soldering portion is restrained and reliability is improved.
