IPC: H01L21/336
Filed: 1988-01-23
Abstract: PURPOSE:To set a threshold voltage value in an range of actual use with a high withstand voltage being maintained, by injecting first conductivity type impurities for forming a source region so that the impurities reach a surface region, which is to become a channel region beneath a gate electrode. CONSTITUTION:A gate electrode comprising an oxide film 2 and poly Si is provided on the surface of an N-type semiconductor wafer. A resist layer 4 is formed on the electrode 3. Ions of impurities such as boron are implanted and diffused in a place where a window 5 is opened. The resist layer 4 is removed. A P-type diffused region 6 for forming a channel is formed. Then, the junction part of a source electrode is covered with a resist layer 7. Ions of N-type impurities such as As are implanted and diffused so as to reach a surface area beneath the gate electrode. The layer 7 is removed. An N-type diffused region 8 for a source region is formed in the surface of the region 6. In this way, a threshold voltage value can be set sufficiently in the range of actual use with high withstand voltage characteristic maintained without increasing manufacturing steps.

Title: Porous sliding sheet
Inventor: KAWAKAMI KANJI
IPC: C08J9/28
Filed: 1979-02-06
Abstract: PURPOSE: To obtain the sliding sheet featuring the excellent hardwearing prperties and antistatic performance by securing the surface resistance, the specific gravity and the porosity each in the specified range to the mixture of the burnt polytetrafluoroethylene (PTFE) and the conductive material.  
     CONSTITUTION: The conductive material (carbon, Cu, etc.) of about 2W75pts.wt. is mixed with the PTFE unburnt powder of 100pts.wt. The conductive material features preferably the surface area of about 20W500m 2 /g and the grain size of about 0.01W150μ each. The liquid lubricant (naphtha, fluid paraffin, xylene, etc.) is mixed with the above mixture, and then the extrusion molding is given after the preform to produce the round rod of the mixture. The round rod is then calendered to be formed into the sheet shape. The sheet thus obtained is then soaked into the trichlene or the like to remove the liquid lubricant and then rolled to be burnt under the rolling state. Thus the sheet is obtained with the surface resistance of 1×10 12 Ω or less, the specific gravity of 0.3W2.7 and the porosity of 20W90% each. Such sheet is used particularly to the inner wall of the magnetic tape cassette or the like in order to reduce the friction force between the cassette and the tape's edge face as well as prevent the charge occurrence.

Title: Optical disk device
Inventor: ASADA AKIHIRO
IPC: G11B7/00
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To reduce unnecessary power consumption and heat generation by making the output voltage variable that is connected to the power terminal of a current to be supplied to a laser diode(LD). SOLUTION: A power supply voltage is supplied from a first power terminal 8, for a driving current control means 6 and an LD current output means 5. The power supply voltage of the entire laser driver 7 is adjusted by a voltage setting means 14 so that both-terminal voltage of the LD current output means 5 becomes a prescribed value (about 1.2 V) in accordance with a forward voltage VF of the LD 10. By setting both-terminal voltage of the LD current output means 5 at the absolute minimum voltage for its operation, its power consumption (product of driving current and both-terminal voltage) by the driving current of the LD 10 can be controlled to the minimum. In addition, since the power consumption of the LD current output means 5 can be reduced, its heat generation can also be reduced.
