Title: Ion activity measuring apparatus and measuring method using the same
Inventor: KONDO ASAJI
IPC: G01N27/28
Filed: 1985-09-11
Abstract: PURPOSE:To enable the measurement of activity and concn. of ions with the mere supply of a liquid sample, by arranging dry and easily water-soluble salt at a desired position to a part of a bridge on the surface of a reference electrode connected to a bridge directly or through a spacer. CONSTITUTION:A liquid sample S is supplied to a liquid sample spotting hole 18 of a porous bridge 17 with a sample spotting device. A part of the sample moves diffusively through the bridge 17 and reaches an area containing a dry salt 19, where a part of the dry salt 19 dissolves into water in the sample and the salt aqueous solution permeates a spacer 201 to reach an outermost ion selection layer 161 of a reference electrode 111 so that an electric conduction will be achieved at the bridge. When the potential difference between the reference electrode 111 and a measuring electrode 112 becomes constant, the potential difference is read out with a potential difference measuring apparatus (A). Thus, the activity or the concn. of ions in the liquid sample (S) are determined by a calibration curve.

IPC: A23L17/60
Filed: 1994-08-03
Abstract: PURPOSE:To obtain a laver, producible in an apparatus at a low cost and having far better tastiness than that of a conventional one. CONSTITUTION:This dried laver is obtained by washing plucked and cultured AMANORI (laver of the genus Porphyra) with water, dehydrating the washed laver, sprinkling the dehydrated laver in a loosened state, drying the resultant laver and regulating the moisture content to about 10%. The drying is preferably carried out by sprinkling the laver after the washing with water and dehydration in the loosened state on a netted shelf of a drying box, exposing the sprinkled laver to warm air at about 50 deg.C and drying the laver or according to freeze-drying or warm heat drying. Thereby, the character of the laver of the genus Porphyra is intactly utilized and the source of tastiness remains. As a result, the taste is excellent.

Title: Semiconductor laser driving device
Inventor: TSUKADA MASAHARU
IPC: G11B7/126
Filed: 1982-11-19
Abstract: PURPOSE:To switch the laser power of a semiconductor laser in two steps with a constant current source by providing a current switching means which modulates the laser driving current on the basis of a fixed level when the information is written. CONSTITUTION:The current flowing to a semiconductor laser 19 is set at levels decided by resistances 12, 13, 15 and 16 respectively to set an automatic focus mode. In a writing mode, a mode switching signal Sc is released, and at the same time a video signal Sv is supplied to a tri-state buffer 11. When the signal Sv is set at a high level, the potential at a point A in the diagram is reduced as compared with that set at an automatic focus mode. In this case, the information is written. When the signal Sv is set at a low level, the potential at the point A is increased as compared with the automatic focus mode. Therefore, the value of the current flowing between the collector and the emitter of a transistor 17 is increased, and the value of the current flowing to the laser 19 is decreased.

IPC: H01L29/792
Filed: 1987-08-14
Abstract: PURPOSE:To prevent short circuits and leaking currents between a first wiring layer end a second wiring layer, by providing a specified interlayer insulating film. CONSTITUTION:The first layer of interlayer insulating films is formed with a silicon oxide film 16. The second layer is formed with a silicon oxide film 19 including phosphorus impurities. The third layer is formed with a silicon nitride film 20. The fourth layer is formed with a silicon oxide film 21 including phosphorus as impurities. A silicon nitride film 20 is formed as an intermediate layer. The etching speed of the silicon nitride film 20 is slower than that of the silicon oxide film 21. The film 20 acts as a stopper at the time of etching. Therefore, the etching when a tapered shape is formed at the upper part of a contact hole 24 is stopped at the silicon nitride film 24. Thus, short circuits between a first wiring layer 15 and a second wiring layer 25, which is formed in the contact hole 24, are prevented. Leaking currents flowing between both layers are also prevented.
