Inventor: KANAMORI SHIYUUJI
IPC: H01L29/808
Filed: 1983-01-28
Abstract: PURPOSE:To obtain the inexpensive FET whose mutual conductance is large, when J-FET having many channels is formed, by changing only the arrangement of a gate regions and source and drain regions by using metallic electrodes without changing the manufacturing process from an ordinary method at all and without decreasing a reverse withstand voltage and a threshold voltage. CONSTITUTION:An N type layer 12 is epitaxially grown on a P type semiconductor substrate 11. The layer 12 is separated by a P type region 13 reaching the substrate 11 into an island shape. P type gate regions 14, N type source regions 15, and N type drain regions 16 are diffused and formed in a shape of  meshes thereon. That is, the source region 15 and the drain region 16 are surrounded by the gate region 14 from all four sides. Therefore the channel regions  formed by the substrate 11 and the gate regions 14 and configured by four sides  with respect to each source region and each drain region. Thereafter, source,  drain, and gate electrodes 18-20 are attached to the respective regions. In this  constitution, the channel regions are doubled and the mutual conductance is also  doubled.

Title: Radio channel assigning method for tdma mobile communication
Inventor: KATSUTA MORITOSHI
IPC: H04Q7/36
Filed: 1994-02-07
Abstract: PURPOSE:To provide the radio channel assigning method for relieving a call at high transmission rate without increasing connection delay by specifying the assigning priority of time slots. CONSTITUTION:When a call is generated, any time slot is allocated by starting the selection from the time slot to be assigned when the call at the same information transmission rate as the transmission rate summing up the information transmission rate for the same kind of plural calls as that call is generated. Namely, when a half rate call H1 is generated, it is first assigned to a slot 201. Next, when a half rate call H2 is generated, it is assigned to a slot 204 away from the slot 201 for three slots. When speaking is finished, this processing is repeated until idle slots to be rearranged are eliminated. Therefore, when a full rate call is generated after this rearrangement processing is finished, it can be completed by two times of processing from call origination to channel assignment.

Title: Electric double layer capacitor
Inventor: SAKATA TADASHI
IPC: H01G11/78
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To provide an electric double layer capacitor having a high reliability and high capacity by increasing the diameter of a polarizable electrode on a positive electrode side to such an extent that it reaches the inner side of a positive electrode can and arranging a pedestal at the periphery of the electrode. SOLUTION: The diameter of one electrode 2 of positive and negative polarizable electrodes is increased to such an extent that it reaches the inner side of a can material, and a pedestal 7 is arranged at the periphery of the electrode 2. When the metal pedestal 7 is provided at the periphery of the positive electrode polarizable electrode 2, a behavior of a negative can 5, namely, a behavior of its sinking toward the positive electrode can 4, due to opening sealing pressure applied at the time of caulking the opening of the positive electrode can 4 inward, is received by the pedestal 7, thus preventing reliability from being affected. Deformation of a gasket due to heat shock and heat cycle is reduced by receiving the load applied to the gasket by the pedestal 7.  When a rate of the polarizable electrodes included in the positive electrode/negative electrode is 1.2 or more in weight ratio, potential applied to the positive electrode is reduced and the withstand voltage of a capacitor is improved while maintaining a high capacity.

Title: Heat pipe device
Inventor: ASAKURA HIROSHI
IPC: F28D15/02
Filed: 1987-01-26
Abstract: PURPOSE:To achieve a good heat transfer by arranging the center of the unit body to be the high or low temperature side and its both ends to be the low or high temperature side while making the inner circumferential wall to be tapered to be increasingly wider from the low temperature side toward the high temperature side, and rotating the heat pipe unit. CONSTITUTION:The heat pipe unit 1 is rotated on its axis by a rotating means 9. The sealed refrigerant 6 is evaporated by being heated on the center high temperature side 3 of the heat pipe unit 1 to become the evaporated gaseous refrigerant, which moves to the low temperature side 4 on both ends where it releases heat to be condensed to become the condensed liquid refrigerant 6. Because the heat pipe unit 1 is rotated, said condensed liquid refrigerant 6 moves toward the low temperature side 4 at both ends having a large diameter along the inner circumferential wall 5 on account of the centrifugal force, where it is heated again to be evaporated for transmission of heat. In this instance, as the condensed liquid refrigerant 6 moves to the high temperature side 3 as it forms a liquid layer on the surface of the inner circumferential wall 5, heat is directly transmitted from the high temperature side 3 to the liquid refrigerant, thereby improving the heat transfer.

Title: Controlling method for serial recorder
Inventor: TANIGURO MASAHIRO
IPC: B41J2/51
Filed: 1989-01-26
Abstract: PURPOSE:To accurately reproduce an image in an effective recording region by controlling the position of a sheet feeding direction of a head in the final line of a recording sheet to prevent the position of the head from exceeding the maximum recording range. CONSTITUTION:A master control system does not first feed a sheet at a normal M line in the final line, but feeds the sheet at a R line of the number of remaining lines. Then, the recording head does not drive recording elements from 1 dot to (M-R) dots corresponding to (N-R) lines from the recorded (N-M+1) lines but drives the recording elements from (M-R+1) dots to M dots in response to the data, thereby recording the remaining R lines. Thus, the lower end of the recording head does not exceed the effective recording region, but can record all the data.
