Title: Triangular-wave generating circuit
Inventor: MATSUURA MICHIO
IPC: H03K4/06
Filed: 1977-12-12
Abstract: PURPOSE:To allow a simple circuit to generate triangular waves with a stable static voltage by making its output waveform depend completely upon an input waveform. CONSTITUTION:When input IN is stable at potential V0, output OUT also remains at nearly V0 and transistors Q1 to Q3 are all ON. If input IN rises in a rectangular shape, the base potential of transistor Q1 rises suddenly and its current increases, so that transistor Q2 will turn OFF. As a result, capacitor C is charged and its output potential OUT rises according to function Ki1 C. Next, when input IN falls and potential decreases down to V0. transistor Q1 turns OFF and transistor Q3 also turns OFF. At this time, since the charged potential of capacitor C2 reaches a certain value, transistor Q2 turns ON to discharge capacitor C2 by way of Q2 and its output potential falls according to a function of i2 C. The gradient of triangular waves varies with the value of K, so that K can be adjusted to any value by adjusting transistors Q1, Q2 and Q3, and resistances R1 and R2.

Title: Manufacture of electrode for fuel cell
Inventor: SAKURAI MASAHIRO
IPC: H01M4/86
Filed: 1983-08-16
Abstract: PURPOSE:To realize an electrolyte-controlling function by forming hydrophilic connection areas in a catalyst layer by thermally decomposing water repellent PTFE contained in parts of the catalyst layer corresponding to electrolyte reservoirs installed in a porous electrode base material. CONSTITUTION:A catalyst layer 3 is provided with areas 8 for connecting electrolyte reservoirs 7 and a matrix 4. The connection areas 8 are not holes or grooves formed in the catalyst layer 3. They are formed for example by giving ultrasonic vibration to spotlike areas of the catalyst layer 3 corresponding to the electrolyte reservoirs 7 to heat and decompose the water repellent binder PTFE contained in the catalyst layer 3 at about 400 deg.C. Therefore the areas 8 are hydrophilic areas which can be permeated by electrolyte. By properly selecting the shape of an electrode used to transfer the vibration of an ultrasonic oscillator, the hydrophilic connection areas 8 which can be well permeated by the electrolyte can be formed in the catalyst layer 3 for example in a dot-like shape with a diameter of around 1mm. or in a linear shape of around 1mm. width. A high dimensional accuracy is achieved by performing such an ultrasonic process.

Title: Apparatus for culture
Inventor: TAMAOKI YUICHI
IPC: C12M3/00
Filed: 1990-06-07
Abstract: PURPOSE:To eliminate the need of a pressure sensor by controlling the gas concentration with a specific controller, simultaneously sensing the residual state of a gas supply source based on a change, etc., in output from a gas concentration sensor and operating an alarm means. CONSTITUTION:The gaseous carbon dioxide concentration in a culture chamber 2 is sensed with an infrared ray sensing type gas sensor 15 to produce a control output in a controller 17 and open or close a valve 11. The aforementioned concentration is controlled to the average set value (SV). The gaseous carbon dioxide concentration [hereinafter referred to as (E)] inputted from the sensor 15 is then periodically [e.g. 1 min interval (S1) to (Sn)] sampled with the controller 17 during the opening of the valve 11 to successively calculate a variation (e) in the concentration (E). If the residual amount of the gaseous carbon dioxide in a gas cylinder 3 is small, the variation (e) is reduced. If the gas cylinder is emptied, the variation (e) attains even 0%. An alarm mean 18 is operated with the controller 17 to raise an alarm (in the same manner for oxygen). Thereby, a pressure sensor and peripheral circuits are not required to sense the residual state of the gas in the gas supply source and the cost is reduced.

The tap hole 5 is opened to tap the molten steel 3 through the tapping region substd. with the substituting gas into the ladle 6. The pickup of nitrogen is, therefore, prevented in the flowing molten steel 3. The clean steel having about <=30ppm content of [N] and <=20ppm total content of [O] is obtd. in this way.
