Title: Ballast circuit
Inventor: KACHMARIK DAVID JOSEPH
IPC: H05B41/282
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To generate the high-voltage spike for starting a lamp by including a pair of series-connected switches for supplying an alternating current power source to a resonance load circuit, and moving the frequency to the natural frequency of the resonance load circuit at the time of starting a lamp. SOLUTION: A high-voltage integrated circuit 16 for automatically generating the high-voltage spike between both ends of a lampLAMP at the time of starting a lamp has a timing input 22 for receiving the timing signal V22 , and the switching frequency of switches S1 , S2 to be generated as a result of the timing input is decided on the basis of the transition time from one threshold voltage to other threshold voltage of the timing signal V22 . When the timing signal V22 is increased from a lower side threshold value and achieves an upper side threshold value, discharge is performed through a timing resistor RT, and switching of both the switches is performed at a transition point.  When both the switches are controlled during the starting period, and the operating frequency of a resonance load circuit 20 is moved close to the natural frequency, voltage between both the ends of the lamp generates a high spike required for starting the lamp.

Title: Semiconductor device
Inventor: WATANABE TAKESHI
IPC: G11C29/12
Filed: 1986-05-23
Abstract: PURPOSE:To easily measure the threshold voltage of a memory element by using a means which can vary the gate voltage of a pseudo memory element. CONSTITUTION:In a normal reading mode control signals VRe and the inverse of VRe are set at L and H levels respectively, therefore the same gate voltage is secured between a memory element M1 and the pseudo memory element MD to obtain the same working as that of a conventional circuit. In a test mode where the threshold voltage of the element M1 is read out, the signals VRe and the inverse of VRe are set at H and L respectively to turn on both IGFETMR1 and GFETMR2. Here the gm of the IGFETMR2 is set larger enough than the gm of the IGFETMR1. Thus VG1 VPP is satisfied. Then the VPP is set at a level in the vicinity of the initial threshold voltage VTOM of the element M1, therefore the element MD has such current characteristics as shown by a curve D in the diagram. Thus VTM-W can be easily obtained by measuring VCC max.

IPC: H01C7/10
Filed: 1988-05-17
Abstract: PURPOSE:To remove noise of a low voltage and the like by a method wherein Sr is contained excessively so as to set a ratio of Sr to Ti at 1.001-1.05 and, in addition, one or more of CeO2, Y2O3 and La2O3 are added to SrTiO3 containing Li and F. CONSTITUTION:An SrTiO3 powder is used as a raw material, Sr is added excessively so as to make 1.001<=Sr/Ti<=1.05, then, a lattice defect is increased, a semiconductor property is promoted in addition, when another element, e.g., Ce, Y or La, is subetituted for Sr, an atomic property is controlled and the semiconductor property is promoted. Then, when LiF is added and this assembly is fired in a reducing atmosphere or in an atmosphere of nitrogen, a sintering operation is promoted by a liquid sintering operation. By this setup, it is possible to obtain an element whose varistor voltage is comparatively low, whose alphaand dielectric constant are large, whose tan delta is small, which can simultaneously satisfy a characteristic of excellent reliability and which can protect a semiconductor or a circuit from a noise and static electricity.

Title: Wiring device
Inventor: MATSUURA TSUTOMU
IPC: H01R13/46
Filed: 1987-05-16
Abstract: PURPOSE:To obtain a wiring device which causes no damage to a user when it is used or operated erroneously by employing a structure permitting the door to be opened to only semi-open condition by an energizing means. CONSTITUTION:A door 22 is energized continuously in an opening direction by a push-up spring 4 under closed condition. But, it is normally secured so as not to be opened by a proper locking means under this condition. Upon release of the locking means, end portion of the door 22 is pushed up by means of the push-up spring 4 so as to open the door as much as a finger can hold it. Then a finger holds the end portion of the door 22 so as to produce properly opened condition of door. Since the wiring device can be opened to only semi- open condition by means of the push-up spring 4, the door 22 is not opened wide abruptly when the device is used or erroneously operated thus protecting a user from damage.

IPC: A61K31/195
Filed: 1991-02-28
Abstract: PURPOSE:To provide a therapeutic medicine for hepatitis such as viral hepatitis, medicamentous hepatitis and fulminant hepatitis. CONSTITUTION:A hepatitis-treating medicine contains at least one of alanine, glutamine and ornithine. The alanine, glutamine and ornithine are recognized to exhibit a remarkable effect for the improvement in the hepatic disease of a galactosamine-damaged liver rat which is a model for the viral hepatitis and the fulminant hepatitis, and induce a hepatic ornithine decarboxylase (ODC) activity which is the indicator of the regeneration of the liver. Since a medicine effective for the regeneration of the liver has not been developed and since the amino acids are considered to exhibit reduced adverse actions, the hepatitis- treating medicine is considered to be highly useful as a hepatitis-treating medicine and further as a cirrhosis-treating medicine.
