Inventor: YOSHIZAWA KOJI
IPC: H01M4/50
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To manufacture a mangangse dioxide which can prevent the remaining of impurity ions inside and whose strong load discharge characteristic is enhanced in a simple process by pulverizing an electrolytic manganese dioxide(EMD), and performing steam high pressure heating cleaning at a prescribed temperature in a pressure vessel. SOLUTION: An EMD electrolytically synthesized from a manganese sulfate solution is separated from a positive electrode, and is pulverized, and when steam high pressure heating cleaning is performed at 100 to 200 deg.C in a pressure vessel, a neutralizing process necessary in the case of a chemically synthesized manganese dioxide is obviated. Therefore, a sodium ion and an ammonium ion used as a neutralizer can be prevented from remaining as impurity, and a manganese dioxide whose strong load discharge characteristic is enhanced can be manufactured in a neutralization unnecessary-simplified process.

IPC: H01L21/336
Filed: 1992-10-06
Abstract: PURPOSE:To provide a local difference at a threshold voltage for inverting a MOS boundary by utilizing, in addition to a work function difference of a gate electrode, a difference of permittivities of gate insulating films, a difference of film thicknesses and further a local difference of impurity concentrations of substrate surfaces. CONSTITUTION:Materials of a first gate insulating film 62 and a second gate insulating film 64 are altered to provide a difference of permittivities and a difference is provided at threshold voltages to be inverted at a MOS boundary. Since a region 53 having higher impurity concentration than that of a well region of a periphery is formed by ion implanting only on the surface of a substrate under a first gate electrode 81, a difference of threshold voltages of the MOS boundary and the threshold voltage of the transistor can be further easily set. In addition, since the electrode 81 and second gate electrodes 51, 61 are electrically insulated, independent potentials can be applied. Accordingly, a local difference can be provided at a threshold voltage for inverting the MOS boundary.

Inventor: KURAISON TORONNAMUCHIYAI
IPC: H01L29/88
Filed: 1992-10-06
Abstract: PURPOSE:To provide a conductivity modulation element capable of much decreasing power consumption. CONSTITUTION:In a conductivity modulation element having a P-I-N junction, a potential barrier region 107 having a fobidden band width wider than that of an N<-> conductivity modulation region 103 is formed between the region 103 and an N<+> cathode region 105. Thereby, as the progress of holes injected from a P-type anode region 101 into the region 103 at the time of energization is obstructed by a potential barrier of the region 107 and can not go to the region 105, conductivity modulation of the region 103 is increased. As a result, the reduction in the resistance of the conductivity modulation element is increased and the power consumption of the element is much reduced.

Title: Facsimile communication method
Inventor: MATSUMOTO KAZUYUKI
IPC: H04N1/21
Filed: 1988-10-24
Abstract: PURPOSE:To eliminate a reception interruption due to a memory-over by deciding whether an allowance exists in a memory to the original quantity predetermined to a transmission start at a receiving side or not and permitting the transmission only when the allowance exists. CONSTITUTION:An unoccupied memory counting part 14 fetches an input to a memory 10, the number B of sheets of originals corresponding to an unused area among a data writing area in a memory 10 is counted from the data input quantity and transmission data, the number of sheets of original data A and the corresponding number B of sheets of originals fetched from a transmission control circuit 9 are compared, a transmission start permission signal is sent to the transmission control circuit 9 at the time of A>B, and a transmission standby request signal is sent to the transmission control circuit 9 at the time of A<B. In such a manner, since a message as to whether the allowance exists in the memory or not is received by a transmission side from the reception side before the transmission is started, the transmission can be put off when the allowance does not exist in the memory. Thus, a wasteful transmission, in which a transmission interruption is generated due to the memory-over in the middle of the transmission, can be prevented.

Title: Manufacture of y-branch waveguide
Inventor: SEKI MASAFUMI
IPC: G02B6/134
Filed: 1988-10-24
Abstract: PURPOSE:To easily manufacture an optical waveguide circuit which has small loss at a Y-branch part by an ion exchanging method by delaying the advance of ion exchange substantially at the branch part where waveguides are close to each other behind that at other areas. CONSTITUTION:For example, when a single waveguide 2a branches into two, the branch part 10 which extends until the branch waveguides separate at a constant interval or more is provided with a 2nd mask film 3 covering the opening part of a 1st mask film 2. In a subsequent ion exchanging process, a material which functions to limit ion transmission to some extent is used for the 2nd mask film 3. Thus, the ion exchange is slowed down relatively at the branch part 10 where the waveguides are close to each other, so an abnormal ion diffusion phenomenon at the branch part 10 is suppressed. Consequently, the branch waveguides which are in nearly the same constant shape with the linear part 10 and have nearly the same constant characteristics are easily obtained by the ion exchanging method and the loss at the branch part 10 is reducible.
