Title: Lithium secondary battery
Inventor: KUSUMOTO YASUYUKI
IPC: H01M10/0525
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a charge/discharge cycle characteristic on practically usable level by using composite sulfide having the same crystal structure as that of tin sulfide or Li containing composite sulfide for an active material for positive or a negative electrode and constituting the composite sulfide of Cu, one or more kinds of other 6 kinds of transition metals, Sn, and S. SOLUTION: Composite sulfide having the same crystal structure as that of tin sulfide and Li containing composite sulfide include transition metals such as Cu, V, Cr, Mn, Fe, Co, and Ni in crystal particles of the tin sulfide and the crystal structure of the tin sulfide is stabilized by substituting a part of Sn by the metal elements. When the composite sulfide is used for the active material for the positive or negative material, the charge/discharge cycle life characteristic of the battery is improved. The composite sulfide can be synthesized by sintering a simple substance, compound, or mixture of the elements constituting it, however, the sintering temperature is preferably set to not less than 231 deg.C and not more than 880 deg.C.

Title: Mos type semiconductor device
Inventor: KURIMOTO KAZUMI
IPC: H01L29/78
Filed: 1987-07-21
Abstract: PURPOSE:To alleviate a high electric field near a drain by providing a diffused layer lower in concentration than a channel in contact with part of a main surface of a semiconductor substrate under a gate electrode in contact with the side face of source, drain diffused layers. CONSTITUTION:When an N-type source diffused layer 2 is grounded, a voltage is applied to an N-type drain diffused layer 3 and a voltage is applied to a gate electrode 1, a low concentration diffused section 7 is first inverted, a channel 6 is further inverted at a threshold value or higher, a switch is closed, and a current flows between the layers 2 and 3. In this case, since the section 7 is inverted, a parasitic resistance is not contained, and a drain current is not reduced as well. Accordingly, its mutual conductance is not decreased. If it becomes not less than a pinch-off voltage, this low concentration diffused section is depleted, and its concentration is low. Accordingly, a depleted layer is extended as compared with a conventional type semiconductor device to prevent an electric field near a boundary of the drain from concentrating.

Filed: 1980-12-24
Abstract: PURPOSE:To achieve picture processing of high quality whose synchronism with the outside never varies with fluctuations of temperature, by adding the extent of compensation specified in a conversion table to the output of a delay circuit by a picture data processing system which uses an oscillating mirror. CONSTITUTION:The extent of compensation of the oscillation phase of an oscillating mirror 15 for fluctuation temperature near the mirror 15 is held as a conversion table. The output of the thermistor 23 of a temperature sensor near the oscillating mirror 15 is converted into a digital signal, and the current fluctuations of temperature is used as an address to read the corresponding extent of compensation out of the conversion table in a read-only memory 21; and it is applied to a delay circuit 13 to adjust the oscillation phase finely. Therefore, picture data from a data acquiring circuit 18 is nearly in phase with the synchronizing signal generating circuit 12.

IPC: F16D43/284
Filed: 1987-07-21
Abstract: PURPOSE:To reduce parts in number as well as cost by constituting a device in such a way that highly viscous oil is forcibly moved in an inner space partitioned by a rotor vane so as to engage respective clutch surfaces depending on relative revolving speeds when both an input shaft and an output shaft are relatively rotated. CONSTITUTION:A rotor 51 and pistons 33 and 34 are relatively rotated upon rotating of both an input shaft 10 and an output shaft 11 relatively because of slip and the like, letting a vane 52 forcibly move highly viscous oil 53 filled in each inner space. As a result, viscous friction is produced on the end surfaces of both of the pistons 33 and 34 so as to develop inner pressure in each inner space for directly acting on the pistons 33 and 34 wherein pressure is increased in proportion to the relative revolving speeds between both of the pistons 33 and 34 and the rotor 51. The pistons 33 and 34 are moved along the shaft while overcoming springs 40 and 41 so as to engage the pistons 33 and 34 mutually with the clutching surfaces 35 and 36 of clutch members 31 and 32 for setting up a four-wheel drive configuration.

IPC: G11B7/24
Filed: 1988-07-21
Abstract: PURPOSE:To eliminate the need for a metallic film as a means for reflecting laser light and to reduce cost by providing a 1st substrate formed with very small rugged recording parts corresponding to recording information and 2nd substrate which is joined to the surface having the recording parts and is joined to the surface side and has the refractive index different from the refractive index of said substrate. CONSTITUTION:The 1st substrate 1 is formed by using a transparent resin, etc., having the relatively small refractive index, for example, a polycarbonate or epoxy system. The substrate 1 is formed with the recording parts 1a having the rugged shapes corresponding to the information on one surface and is so formed as to reflect the laser light entering from the lower side on the boundary of the substrate 1 and the substrate 2 by utilizing the difference in the refractive index. The substrate 2 is formed of the resin having the refractive index larger than the refractive index of the recording region 1, for example, a polysilane, etc. The reflectivity of the required level is assured in this way even if there is the metallic film required heretofore and, therefore, the drastic reduction of the production cost is attained.

Title: Semiconductor storage device
Inventor: TAKIMOTO ISAO
IPC: G11C11/418
Filed: 1987-07-21
Abstract: PURPOSE:To execute the same function as a convention one with a smaller number of transistors by composing a logic circuit to output only two conditions of an 'H' level and a high impedance condition. CONSTITUTION:While a conventional logic circuit outputs the three conditions of the 'H' level, the high impedance (Hi-Z) condition and an 'L' level, the constitution of a logic circuit 3 is made into one whose output terminals WO and the inverse of WO go to the 'H' level or the high impedance condition based on a data input signal and a reading-writing signal. Consequently, the transistors and circuits to output the 'L' level to an output can be reduced. Thus, a semiconductor storage device with the smaller number of elements can be obtained which has the same function as a conventional example.
