Title: Ic element and its packaging test method
Inventor: KISHIGAMI KEICHU
IPC: H05K13/08
Filed: 1988-11-29
Abstract: PURPOSE:To find out a fault which can be detected only by visual observation by previously short-circuiting specified lead pins in an IC element with each other in a circuit inside the element and performing an open short-circuiting test between the pins. CONSTITUTION:In a gate array IC 10, for example, the lead pins 161 and 163 are connected with each other by a short-circuiting circuit 18 inside an element main body 14 to obtain the constitution where the pins 161 and 163 are short- circuited. On both side of the pattern of a printed board 12 where the IC 10 is packaged, the test pin 24 of an incircuit tester 22 is brought into contact with a test land corresponding to the pins 161 and 163. Thus, when the regular IC 10 is packaged in a regular state, it is decided to be a short-circuiting state owing to the existence of the circuit 18. When it is decided to be an open state, it means that the IC 10 is not packaged or that different parts are packaged or that the IC 10 is packaged in a wrong direction. Even if the IC 10 is erroneously packaged at a point symmetric position, it can be detected, especially, since the pins 161 and 163 are placed in a positional relation asymmetric to the element main body 14.

Title: Gas sensor element
Inventor: KOBAYASHI SHIGEAKI
IPC: G01N27/416
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To reduce influence of thermal deformation and the like by pressing a reference electrode and a detection electrode to an ionic conductor abutting on both the electrodes by use of an elastic force of an elastic body. SOLUTION: In this gas sensor element, a panel heater 12 is placed on a heat insulating material 5 placed on a holding plate 6, while a solid electrolyte 11, i.e., an ionic conductor, is placed on the panel heater 12. A reference electrode 9 and a detection electrode 10 are disposed on the solid electrolyte 11, while a heat insulating material 2 is placed on a ceramic plate 8 placed on both the electrodes 9, 10. An end part of a reverse J-shaped element pressing rod 7 for applying a downward pressing force is abutted on the heat insulating material 2. An end part of a long side of the element pressing rod 7 penetrates through the holding plate 6 to project outside, while the downward pressing force is applied to the element pressing rod 7 by a coil spring 13 provided around the projecting part.  Thereby, an end of a short side of the element pressing rod 7 presses the reference electrode 9 and the detection electrode 10 to the solid electrolyte 11 through the heat insulating material 2 by the energizing force of the coil spring 13. Accordingly, when the gas sensor element is operated by heating, influence of thermal expansion of respective components in respective longitudinal and lateral directions can be sufficiently reduced.

Title: Emergency generator
Inventor: MATSUMURA TAKEO
IPC: H02J15/00
Filed: 1991-11-18
Abstract: PURPOSE:To obviate the necessity of external fuel supply and to obtain an emergency generator causing no pollution by normally storing hydrogen gas and feeding thus stared hydrogen gas as emergency power supply at the time of emergency. CONSTITUTION:A water electrolyzer 23 normally produces hydrogen gas using excessive power in a vessel and thus produced hydrogen gas is absorbed by hydrogen-occlusion alloy filled in a tank 25 and stored in the form of metal halide. Upon interruption of a main power supply 21 due to some cause, thermally controlled hydrogen gas is taken out from the hydrogen-occlusion alloy and then fed to a fuel cell 26 where the hydrogen gas chemically reacts with the air to produce electricity which is fed as emergency power. According to the constitution, an emergency generator causing no pollution can be obtained which can be operated with no noise or vibration without requiring external fuel supply.

Title: Tape cassette
Inventor: ISHIKAWA TAKAHITO
IPC: G11B23/34
Filed: 1992-11-12
Abstract: PURPOSE:To obtain a tape cassette capable of preventing a head damage in the mechanism with short tape path and also a tape damage in the mechanism for which the high speed tape running is requested. CONSTITUTION:In respect to thin films for detecting the start/end points, which are stuck to the surface of the tape 1, the length of the thin film baked on a protective film layer 9 which is a non-recording layer, is made longer than that of the thin film baked on a magnetic layer 8. By the reason that detection parts for detecting the start/end points provided on the magnetic layer 8 for tape and protective film layer 9 are different in length for each layer, no concern is required for the generation of damage to the head in the mechanism with short tape path length such as a movie, since the detection part is short in length at the side of magnetic layer for tape. Further, by detecting the start/ end points at the side of tape protective film layer 9 having the long enough detection part, the running into the start/end points of tape at the time of FF and REW in the mechanism such that the tape runs at high speed like an FC compatible deck, is also prevented.

The capacitors Ca, Cb are selected such that the total capacitance thereof will be equal to the capacitance thus determined.

Abstract: PURPOSE:To eliminate the folding of a leading end part by once rotating only a platen roll in a reverse feeding direction after cutting, separating the last recording paper of one cycle and retreating the leading end part after the cutting of the roll paper from a cutting position. CONSTITUTION:When the recording paper printed by one page passes through a cutter 6 and a position to be cut is fed so as to face the cutter 6, a motor 17 is stopped and simultaneously rolls 5 and 7 are stopped. Then, a movable blade 20 is turned downward, the cutting and separation are executed, and the recording paper is cut away from the leading end part of roll paper 3. In this case, the leading end part of the roll paper 3 is abutted on the bottom surface of a cutter guide upper plate 24 and folded. The platen roll 5 is rotated in the direction of an arrow mark R, the leading end part is retreated in a reverse feeding direction UF, and returned to a home position. Thus, the leading end part abutted on the cutter guide upper plate 24 and folded is separated from the cutter guide upper plate 24 and the folding is eliminated.

Title: Ozone deterioration detecting device for photosensitive body
Inventor: NINOMIYA EIJI
IPC: G03G15/00
Filed: 1988-11-29
Abstract: PURPOSE:To accurately detect ozone deterioration at low cost by comparing a measurement signal for deterioration detection which is obtained by detecting the density level of a developed pattern for deterioration detection with a reference value and detecting whether or not there is the ozone deterioration. CONSTITUTION:The reference value is generated by reading a ground level and then lateral stripes, namely, the pattern for deterioration detection is formed on a photosensitive drum 1. Then a reflection type photosensor 9 reads the lateral-stripe pattern and the output of this sensor 9 is inputted to the inverted input terminal of a comparator 13 as a measurement signal through an amplifying circuit 11. The reference value is inputted to the uninverted input terminal of the comparator 13 and the measurement signal obtained from the lateral stripe pattern is compared with the reference value. The comparator 13 outputs a signal which goes up to high level when the measurement signal is higher than the reference signal. Consequently, the deterioration of the photosensitive drum 1 due to ozone is detected directly.
