Title: Memory test method
Inventor: FUJIWARA EIJI
IPC: G11C29/56
Filed: 1987-04-24
Abstract: PURPOSE:To attain a high-speed test method for a memory with high accuracy by compressing an address and a write data by utilizing a write-operating time, obtaining a true signature value automatically, and comparing the result with a read-out time value. CONSTITUTION:A write address information and a write data are inputted in parallel to a linear feedback register LFSR 6-1, and are compressed, so that a true signature value is generated automatically at the tie of writing. Meanwhile, in order to check whether or not data are correctly written in all the addresses of a memory cell array 1, data are read out from the memory by the same address sequence as that of the writing. The address information and reading out data obtained at this time, are supplied to an LFSR 6-2, and its output is compared with that of the LFSR 6-1 by a comparator 7. If the data are correctly written in the array 1 and are correctly read from there, the signature values stored in the LFSRs 6-1 and 6-2 are to be coincidence with each other. Therefore, the memory can be tested accurately and rapidly.

Title: Uninterruptible power supply device
Inventor: NAKANO HIROTAMI
IPC: H02M7/48
Filed: 1993-04-03
Abstract: PURPOSE:To improve the electromagnetic environment of a load by connecting the connection point between first and second capacitors to the tap of a tap inductance connected to a power supply terminal in parallel or a neutral point terminal. CONSTITUTION:Smoothing capacitors CA and CB are connected between power lines 7 and 8 connected to the DC output terminal of a converter 1. The connection point N between the capacitors CA and CB is connected to a neutral point terminal P via a connection PN, thus preventing the voltage between the neutral point on the side of a power supply EO and power lines 7 and 8 from fluctuating greatly by the switching operation of switches Q1-Q4 of the converter 1. Furthermore, the voltage between the neutral point of a load 3 and the neutral point on the side of the power supply EO is hardly disturbed by the switching of the converter 1, thus effectively reducing trouble noise to the load 3 or other electronic devices and hence improving the electromagnetic environment on the side of the load 3.

Title: Degradation detecting method and device for engine exhaust gas purifying catalyst
IPC: F01N3/24
Filed: 1992-03-25
Abstract: PURPOSE:To judge degradation highly accurately by carrying out a feedback operation according to an output value of the first oxygen sensor so that an air fuel ratio can be kept in a prescribed air-fuel ratio, and judging the degradation of catalyst according to an output value of the second oxygen sensor. CONSTITUTION:An air exhaust system 1 has a catalyst converter 3 enclosing NOx purifying catalyst 2. After it is operated for a prescribed time prior to detection on degradation of the catalyst 2 in a rich condition where an air excessive ratio (actual air-fuel ratio/stoichiometric air-fuel ratio) is equal to or smaller than 1, a feedback operation is carried out according to an output value of the first oxygen sensor 4 so that the air-fuel ratio can be converged into the stoichiometric air-fuel ratio. When feedback control is carried out on this air-fuel ratio, the degradation of the catalyst 2 is judged according to an output value of the second oxygen sensor 5 arranged downstream of the catalyst 2. In this way, a degradation condition of the catalyst can be detected highly accurately.

Title: Production of sterilized egg white liquid
Inventor: TANAKA TADAMITSU
IPC: A23L15/00
Filed: 1979-08-08
Abstract: PURPOSE: Liquid egg white is combined with sucrose and a potassium or sodium salt of condensed phosphate and the mixture is subjected to sterilization, thus producing the title sterilized egg white liquid that has the same level of whipping ability as that before sterilization.  
     CONSTITUTION: To 100pts.wt. of liquid egg white, are added 10W50pts. of sucrose and 0.5W1pt. of a sodium or potassium salt of condensed phosphate or a mixture of 2 or more of them. The addition of less than 10pts. sucrose reduces the effect while exceeding 50pts. is undesirable because the sucrose tends to crystallize out. The addition of less than 0.5pt. condensed phosphate can not cause the sufficient effect, while exceeding 1pt. is undesirable because there is the possibility of changing the taste of the liquid egg white. Since the sterilization is carried out for the purpose of making the Bacillus colitis and Salmonella negative in the liquid egg white, the heating is effected, e.g., at 58°C for 5min and at 63°C for 3min.

Title: Open/close unit and western-style toilet bowl therewith
Inventor: ASADA KYOJI
IPC: A47K13/12
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To close a toilet seat and a lid manually or automatically with a simple mechanism and especially prevent a heater for a toilet seat from radiating heat. SOLUTION: This open/close unit comprises a shock-absorber means for rotationally opening/closing an open/close member 2 such as a toilet lid, a driving power source 5 for rotating the fully opened open/close member 2 to a rotatable position with its own weight, a transmission gear 60 to be rotated by the driving power source 5, a damper gear 24 for transmitting the rotation force of the transmission gear 60 toward the open/close member 2, a feed gear 61 to rotate together with the transmission gear, and a pair of teeth formed on the feed gear 61 and the damper gear 24 respectively.  When the fully opened open/close member 2 is made to do the closing movement by the driving power source 5, the feed gear 61 rotates to feed the damper gear 24 forward and the open/close member 2 is rotated at a wider angle than the angle allowing the open/close member 2 to do the closing movement by its own weight. After that, the engagement between the feed gear 61 and the damper gear 24 is released. When the open/close member 2 is made to do the closing movement manually, the rotation power of the teeth of the damper gear 24 is not transmitted to the teeth of the feed gear 61, so only the damper gear 24 can be rotated.

Title: Composite camera built in with strobe
Inventor: OOSAWA SHIYUUZOU
IPC: G03B15/05
Filed: 1979-08-10
Abstract: PURPOSE: To achieve the improvement in the performance of a composite camera built in with a strobe by providing an electric power source for the film winding circuit of a still camera and an electric power source common to the strobe circuit and the film driving circuit of a cine camera.  
     CONSTITUTION: At the time when the still photographing using a strobe is to be performed, the film winding operation after shutter release and strobe charging operation are started separately because an electric power source for automatic winder and an electric power source E for the strobe are separately provided. Hence, the strobe charging operation takes place rapidly. Next, if a switch Sc is closed at the same instant of the charging starting of the strobe by trying to perform shooting with the cine camera during the strobe charging operation, a switching circuit 13 maintains an off state and prevents electric current from flowing to a motor M, hence the cine photographing cannot be made but when the charging of the strobe progresses, the switching circuit 13 goes on and even during strobe charging, the cine photographing becomes feasible after lapse of a fixed time. Thus, the performance is made higher.
