Abstract: PROBLEM TO BE SOLVED: To provide a sleeper which is reduced in weight without degrading the physical properties thereof such as strength, exhibits increased ease in handling such as in transportation, is prevented from cracking and crazing due to hammering of dog spikes, and can be increased in economical efficiency. SOLUTION: The density of a reinforced resin with respect to a base resin 1 is increased at upper and lower portions of a sleeper relative to a central portion of the same, and a cavity 5 is formed in the central portion along the longitudinal direction of the sleeper. As a result, the material and weight of the sleeper can be reduced without degrading the strength of the sleeper, and the cost can be curtailed. Further, by defining the location of the cavity 5 or the location and size of the same formed in the standardized synthetic sleeper to an optimum range, not only the strength of the synthetic sleeper can be prevented from being degraded, but also cracking and crazing of the sleeper occurring when dog spikes are hammered can be prevented, which leads to increased reliability of the sleeper.

Title: Probability generator and random number generator
Inventor: YAMAMOTO HIROYASU
IPC: H04L9/22
Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To generate a correct probability value even when the average number of pulses per unit time is changed in a probability generator utilizing the random generation of radiant rays from a radioactive substance or white noise from a diode. SOLUTION: A memory 9 sequentially stores the average number of pulses per unit time measured by a measuring circuit 3. A clock correction circuit 6 changes the clock period of a clock pulse generator 11 so as to cancel the increment/decrement of the average number of pulses when the average number is changed. Consequently the same probability value is obtained even when the average number of pulses per unit time in a random pulse source 10 is changed. A pulse evaluation circuit 7 defines plural sections by dividing a time interval and judges whether the number of pulses included in each section is based on prescribed exponential distribution or not. Consequently whether pulses are generated from the random pulse source 10 always at random or not, i.e., whether an appropriate probability value is obtained or not, can be easily judged.

Title: Digital radio repeater
Inventor: YOSHIMOTO MAKOTO
IPC: H04B17/40
Filed: 1988-11-25
Abstract: PURPOSE:To shorten frame synchronizing recovery time as an entire system by outputting a data signal inputted to a signal processing circuit as it is when out of frame synchronism of a frame synchronizing circuit is caused. CONSTITUTION:The repeater is provided with a receiver 1, a demodulator 2 demodulating an output of the receiver 1 and outputting a received section 3 applying signal processing to the received data signal dr and outputting the transmission data signal dr, a modulator 4 outputting a modulation signal modulated by the transmission data signal dt and a transmitter 5 sending the output of the modulator 4. When frame synchronizing step-out takes place, the data signal inputted to each signal processing circuit requiring the frame signal is outputted as it is. Thus, the acquisition of the frame synchronizm is attained in parallel at the same time without awaiting the re-establishment of the frame synchronization of a preceding station by each succeeding station to an intermediate station and the intermediate repeater station whose frame synchronism is stepped-out. Thus, the frame synchronizing recovery time as the entire system is shortened.

Title: Formation of transparent electrode
Inventor: IMAYOSHI KOJI
IPC: C03C15/00
Filed: 1993-11-29
Abstract: PURPOSE:To form a transparent electrode in a fine pattern with excellent size precision. CONSTITUTION:An ITO thin film 2 is formed on an insulating substrate (glass) 1 in 150 deg.C or lower substrate temperature condition by sputtering and after a photoresist 3 in an electrode pattern is formed on the ITO thin film 2, the part coming out of the photoresist 3 of the ITO thin film 2 is removed by etching to give a transparent electrode 2. Since an acid mixture of hydrobromic acid and phosphoric acid is used as an etchant in this method, side etching is suppressed at the time of the etching treatment and the width of the image line of the ITO thin film 20 which should be left after etching can be controlled precisely. As a result, a transparent electrode 20 in a fine pattern with excellent size precision can be formed.

Title: Residual ink ribbon detection device of image forming apparatus
Inventor: JINNO TAIICHI
IPC: B41J17/36
Filed: 1987-11-26
Abstract: PURPOSE:To detect the residual amount of an ink ribbon to be supplied from a feeder roller precisely and enabling correct display of detection results by detecting the rotating speed of the feeder roller or a winding roller as its rotating speed changes in accordance with the unused portion of the ink ribbon. CONSTITUTION:The period T of a pulse signal generated by a photointerrupter 46 is detected. An ink ribbon moved by 1/30.8mm by driving a stepping motor for driving a winding roller one step. Consequently, the peripheral speed upsilonmm/s of a feeder roller 36 is N/30.8, if the rotating speed of the stepping motor is Npps. Furthermore, the feeder roller 36 rotates once in a time twice as much as the period T, so that the following relationship is established between the radius(r) of the ink ribbon 35: 2T=2pir/upsilon. Accordingly, the ribbon radius(r) can be calculated as a criterium of an actual residual ribbon based on the above formula of relationship and the period T detected by a timer. A display is made by outputting a signal to a display part 43 according to the calculation results.

Abstract: PROBLEM TO BE SOLVED: To stabilize flow velocity and ensure a satisfactory measuring accuracy by placing a flow velocity measuring bent surface body like a hollow open at both ends in a measuring pipe and forming one or more cut recesses into the sidewall of the bent surface body from an opening to the middle. SOLUTION: When as shown by white arrows, a gas or other fluid flows into an ultrasonic flow velocity measuring pipe 1, it flows from the left opening of an elliptic shell 7 and a cut recess 9 into the shell 7 flows therein and drains from the left opening and the recess 9 to the outside of the shell 7.
