Title: Spin detector
Inventor: KOIKE KAZUYUKI
IPC: G01N23/20
Filed: 1995-02-17
Abstract: PURPOSE: To efficiently detect a spin condition even on an electron beam having a large electric current value by using plural electron detectors in detection of a single component of a spin polarized vector. CONSTITUTION: An electron diffusion detecting part is composed of a gold thin film 2 and electron detectors D1 to D12 arranged in an annular shape in the ϕ direction. The detectors D1 to D12 have respectively a trapezoidal detecting surface, and detect an electron on which a polar angle of diffusion and an azimuth angle are 100 degrees <= θ <= 140 degrees and 30n degrees <= ϕ <=30(n+1) degrees among electrons diffused by the gold thin film 2. Herein, (n) is an integer of 0 to 11. When the electron numbers detected by the detectors D1 to D12 are respectively denoted by N1 to N12 , a polarized degree can be calculated by numeric processing from these electron numbers N1 to N12 . Therefore, even on an electron beam having a large electric current value, the polarized degree can be detected without reducing detecting efficiency.

Title: Method for detecting point volume of gas leaked from gas duct
Inventor: NUKUI KAZUMITSU
IPC: G01M3/00
Filed: 1995-02-17
Abstract: PURPOSE: To obtain a method for detecting the gas leak point and the volume. of leaked gas in a gas duct, e.g. the service pipe of city gas. CONSTITUTION: In the method for detecting leakage of gas from a duct 2 coupling between a main or branch pipe 1 and a gas meter 3, the gas meter 3 is provided with a pressure sensor 5. At some moment of time, pressure difference is measured by means of the gas meter 3 between a case where no gas flows through the duct 2 and three cases where gas flows through the duct at different flow rate. Assuming the pressure losses and the volumes of leaked gas at the duct part between the main or branch pipe 1 and a leak point L and at the duct part between the leak point L and the gas meter 3 at some flow rate are unknowns, simultaneous equations of three elements comprising equations of the differential pressures for three flow rates and the measured differential pressures are solved thus determining the gas leak point and the volume of leaked gas.  Since the gas leak point and the volume of leaked gas can be detected for the duct between the gas meter 3 and the main or branch pipe 1 without digging the ground surface, manpower can be reduced.

CONSTITUTION:Air of a burner cover 60 is heated by heat of an auxiliar burner 36 and lifted to flow into an engine cover 58 from a window 68. Here the outside air flows into the cover 60 from an opening 70 in a bottom part of the cover 60. The air flowing into the cover 58 is further heated by an engine 10 and lifted. In consequence, high temperature air is accumulated in an upper part of the cover 58, and heat of this high temperature air is collected to engine cooling water by an engine compartment heat recovery device 30. A part of this high temperature air is discharged to the outside from a gas discharge window 66. If a leak of gas is caused in a place for use of gas, the gas is collected to the uppermost part of a cover 56, that is, a recessed part 62. If concentration of the gas in the part 62 becomes at least a fixed value, a gas sensor 64 operates to detect a leak of gas.

Title: Non-volatile storage device
Inventor: YAMASHITA MASAYUKI
IPC: G11C16/06
Filed: 1990-02-08
Abstract: PURPOSE:To decrease the number of leaked current paths generating a memory cell to be connected to a bit line, and to stablize operations by commonly connecting only the source of the memory cell to be connected to a word line and connecting an MOS transistor at an interval with a ground potential. CONSTITUTION:At the time of write, a first address select signal 2 is selected and at such a time, a first MOS transistor Tr1 is conducted. At such a time, a second address select signal 5 is not selected and a second Tr4 is not conducted. When a bit line B1 is turned to 9V and the word line is turned to 12.5V, a memory cell 1.1 is selected and written. Then, memory cells M3.1 and M4.1 connected to the line B1 cuts the path from the source to a ground potential 3 by not conducting Tr4, and the leaked current is not generated in this path. Similarly, at the time of read, the Tr4 is not conducted and the leaked current is not generated. Thus, the number of leaked current paths to the ground potential to be connected to one bit line is decreased and both write/read operations can be stablized.

Title: Message sound recording system
Inventor: YAMADA KAZUHISA
IPC: H04M1/65
Filed: 1992-02-18
Abstract: PURPOSE:To improve convenience by continuing sound recording in the other direction area when one sound recording area is full and to transmit the voice during a temporary sound recording stop to a sound recording source until the sound recording is restarted. CONSTITUTION:A rotation frequency measurement means 102 measures and monitors the rotation frequency of a sound recording and reproducing means 101 and when it is coincident with the threshold rotation frequency of the sound recording area of the means 101, a traveling direction inversion means 103 inverses the traveling direction of the means 101. A switching voice transmission means 104 sends a voice so as to allow a message sound recording source to stop sound recording to an automatic answering telephone set 100 before the inversion in the traveling direction is finished and the sound recording is enabled in the inverted direction. Therefore, even if the message sound recording area in one direction becomes full, the sound recording in the message sound recording area in the other direction is immediately continued. Since before the sound recording is enabled again by inverting the traveling direction and the voice made temporarily to stop recording is sent to the sound recording source, messages are prevented from being deleted resulting in improving the convenience of the device 100.

Filed: 1990-02-09
Abstract: PURPOSE:To obtain the title composition with good sinterability, capable of giving internally uniform porcelain with excellent characteristics by providing such a specific composition as to contain a specific trivalent metallic ion and control the content of Zn therein to a required value. CONSTITUTION:The objective porcelain composition of the formula with X, Y and Z each limiting the composition range satisfying the values described as follows: X+Y=1; 0.3<=X<=1; 0.7<=Y<=0; 0<=Z<=1. The reason why the X and Y have been limited as mentioned above are: if X is <0.3 and Y>0.7, the present porcelain composition will be significant in the degradation in the Q-value and also become larger in the degradation in the temperature coefficient; on the contrary, when X is >1 and Y being 0, the improving effect for the Q-value will not be seen. Furthermore, by limiting the Z-value as described above, the temperature coefficient for resonance wave number can be selected at one's discretion.
