Title: Ethanol sensor
Inventor: NANBA AKIRA
IPC: G01N27/30
Filed: 1987-10-09
Abstract: PURPOSE:To obtain an ethanol sensor making a response with high sensitivity in 1-2min, by combining an enzyme-modified electrode having an enzyme of an acetic acid bacteria mixed as an electrode component, with a reference electrode. CONSTITUTION:An acetic acid bacteria is refined and isolated, or a bacteria body is used as an enzyme source as it is. An enzyme sample thus obtained is mixed in graphic powder and liquid paraffin and applied on the surface of a carbon electrode, so as to prepare an enzyme-modified carbon electrode containing a cell membrane coupling type alcohol dehydrogenase as an electrode component. This electrode is immersed in a bath in which an ethanol-containing sample including an electrolytic solution is put, and is electrified with a reference electrode as an opposite electrode. An oxidation current thus generated is voltage-converted and recorded. A sample solution is prepared to be pH4-7, so as to make an enzymic reaction proceed smoothly. Besides, an auxiliary electrolyte such as KCl is made to be contained and ferricyanide or the like is added, so as to smooth the flows of electrons produced in a reaction and electrons between the electrodes and to increase sensitivity. According to this constitution, a time for response is shortened to be 1-2min and a simple ethanol sensor is obtained.

Title: Electric field emission type ion source
Inventor: NODA TAMOTSU
IPC: H01J27/26
Filed: 1985-11-15
Abstract: PURPOSE:To enable to pick up ion beams of high brightness stably and for a long period of time, by furnishing a covering layer of heat-resistance, consisting of a substance to be ionized and a non-reactionary substance on the surface of a heater. CONSTITUTION:Over a spiral form or boat form heater 1 installed with a tip 2, is formed a covering layer 4 by pasting and sintering alumina powder. The covering layer is formed by soaking the heater 1 and the tip 2 in a suspension (including a binder) of alumina powder, causing to glue alumina over them, and then by sintering in a high temperature furnace. The pasting can be controlled as required by selecting the density of the suspension. In such a way, ever though a reactionary material is used as a substance to be ionized, it will never react with the heater and the tip, and ion beams from such a material can be picked up stably for a long period of time.

Title: Abnormal sound preventive device at the time of engagement of car locking device
Inventor: HAMAGUCHI OSAMU
IPC: E05B77/40
Filed: 1990-09-25
Abstract: PURPOSE:To prevent the generation of an abnormal sound while reducing damage due to abrasion by turning a projecting section formed to one part of a resin latch surrounding the outer surface of a metallic latch while being slid on the inner surface of a circumferential wall made of a synthetic resin. CONSTITUTION:A projecting section 22 with a small projecting section at a front end is formed to one part of a resin latch 21 surrounding the outer surface of the metallic latch 20 of a latch 4, and the projecting section 22 is rotated while being slid on the inner surface of the circumferential wall 25 made of a synthetic resin of a recessed section 2. Since the small projecting section of the front end of the projecting section 22 of the latch 21 is turned while being slid on the arcuate inwall 27 of a body 1, the generation of an abnormal sound is prevented. Damage due to abrasion is reduced so that the small projecting section and an inwall 27 are brought into contact during a time when the latch 4 is moved from the intermediate position of half and full to full. The quantity of lapping is increased because of the mutual contacts of the resin, thus preventing the movement at a final stage.

Filed: 1987-10-13
Abstract: PURPOSE:To stably perform information recording with high reading accuracy by providing a diffusion part whose magnetic characteristic is different from that of a base material on the base material, and storing information by the diffusion part. CONSTITUTION:A magnetic change layer of linear shape or plane shape, that is, the diffusion part 3 whose magnetic characteristic is different from that of the base material 1 consisting of a magnetic grid is formed on one side or both sides on the surface part or the inside of the base material 1. The diffusion part 3 generates remarkable residual stress because it receives a steep cooling function, and it is provided with a large coercive force because it includes a large carbon content, and large residual magnetization is generated by magnetizing it. Also, it is possible to decrease irregularity on the surface of the base material 1 to a negligible degree. Therefore, it is possible to record arbitrary information by selecting an interval or width, or the combination of them to project a laser beam arbitrarily. In such a way, reading can be performed even after a process such as painting, and also, it is possible to heighten reading accuracy stably without generating peeling, etc., in case of a temperature change.
