Title: Semiconductor device
Inventor: TAGO HARUYUKI
IPC: H01L21/8236
Filed: 1980-03-13
Abstract: PURPOSE:To shorten retardation time while maintaining consumption power by a method wherein an enhancement type transistor and a depletion type transistor are arranged on the input and output sides of the transmission channels, respectively. CONSTITUTION:The source electrode of an enhancement type transistor Tr31 which functions as a driving element is earthed so that an input voltage Vin is applied to the gate electrode. The drain electrode of the Tr21 is connected to the source electrode of a depletion type Tr23 with the gate electrode earthed via a wiring circuit 22. In addition, the drain electrode of the Tr23 is connected to the source electrode of a depletion type Tr24 which functions as a load element, and an output terminal 15 is taken out of the drain electrode of the Tr23. The threshold voltage value of this Tr23 is negative and its absolute value is so arranged that it is smaller than the power source voltage Vcc. In other words, since the gate potential of the Tr23 is fixed at OV, the source potential is less than the threshold voltage of the Tr23. This is able to shorten the charging and discharging time of wiring volume Gs, thus making it possible to raise the speed of circuit operation.

Title: Thermoelectric element
Inventor: YAMAZAKI TAKUYA
IPC: H01L35/08
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To improve durability almost without reducing response speed by a method wherein alumina cement is applied to the surface on the high temperature end of a thermoelectric element base material. SOLUTION: Alumina cement 4 is applied to the surface on the side of the high temperature end 1A of a thermoelectric element base material 1. The desirable thickness of the applied layer of alumina cement is 0.3 to 0.5mm. No sufficient durability effect can be obtained in the thickness less than 0.3mm, and response is impaired when thickness exceeds 0.5mm. It is desirable that the length of the region where alumina cement is applied is 1/5 to 1/2, preferably length is about 1/3, of the whole length of the thermoelectric element base material from the high temperature end part in order that the quantity of the heat from the low temperature side is not decreased. As a result, the durability of the thermoelectric element can be improved without lowering response speed.

Title: Magnetic head device
Inventor: YAMANE YASUTAKA
IPC: G11B5/265
Filed: 1983-02-28
Abstract: PURPOSE:To assure the reading/writing of data by forming the core parts of the read/write gap side and the erasion gap side with inclinations to each other in the vertical direction to the recording surface and setting these gaps in parallel to each other. CONSTITUTION:For a read/write core 4, a core part 10 is formed at the side of a read/write gap 2 in the vertical direction to a recording surface 1. The part 10 has a mutual inclination to a core part 11a at the side of an erasion gap 3a for an erasion core 5. In addition, the parts 10 and 11a cross each other, and gaps 2 and 3a are parallel to each other. Thus the distances between the gap 2 and gaps 3a and 3b are virtually eliminated. This avoids a contact between a read/ write coil 6 and the part 11a as well as a contact between an erasion coil 7 and the part 10. Therefore an approximately equal working time is obtained with gaps 2, 3a and 3b respectively. Thus only the data in the region of the core 4 can be kept assuredly, and the undesired data can be eliminated at both side regions.

Filed: 1993-01-28
Abstract: PURPOSE:To enhance the durability by forming a boom body composed of split sections which are separated from each other along a sectional neutral axis, longitudinal of the body, so as to prevent high stress caused by a waking load, from concentrating to a welded part. CONSTITUTION:The body 12 of the boom structure 10 is vertically split into an upper boom body 12A and a lower boom body 12B by a split line 22 along a neutral axis along which a vertical neutral plane in the cross-section of the body and a boom side wall surface cross together, and the upper boom body 12A and the lower boom body 12B are integrally welded together. Then, the structure 10 is installed on a working vehicle so as to perform working, and accordingly, a load is exerted to the structure 10, resulting in that high strength is induced at a corner part of the body 12. However, since the corner part of the body 12 has a structure which is formed by bending a one sheet, and since the welded position is located on the split line 22, no high stress is induced in the welded part. Accordingly, a stress reducing effect in the welded part is enhanced, thereby it is possible to enhance the durability of the structure 10.
