Title: Handset unit having directivity
Inventor: ISHIZAKA TETSUO
IPC: H04M1/62
Filed: 1981-09-11
Abstract: PURPOSE:To improve the articulation, by collecting sound so as not to deteriorate signal spectrum of voice, through the insertion of an emphasis circuit which corrects the deterioration of signal level at high frequencies to a mixed output of microphones arranged in a line. CONSTITUTION:Uttered voice is collected with all microphone units 4-1-4-n, and amplified by preamplifiers 7-1-7-n respectively and mixed at a mixing circuit 8 to be one output and given to an emphasis circuit 11. The emphasis circuit 11 amplifies a signal level of an output signal given from the mixing circuit 8 with emphasis only to the component with a specific frequency band and transmits the signal to a transmission terminal 10. Thus, the gain versus frequency characteristic of the circuit 11 corrects the reduction in the signal level at this frequency and makes the frequency characteristic of the mixed output of collected sound flat. Thus, since the signal spectrum of uttered voice can be collected without deterioration, conference and lecture with excellent articulation can be performed.

Title: Vertical field-effect transistor
Inventor: SAWAJIMA HAJIME
IPC: H01L29/78
Filed: 1986-06-18
Abstract: PURPOSE:To inhibit the spreading of a depletion layer into the interior of a drain layer at the time of conduction, to take spaciously the effective sectional area of a of conduction part and to suppress small the resistance of a junction FET part by a method wherein a diffused layer which has the same conductivity type as that of the drain layer and has an impurity concentration higher than that of the drain layer is formed in such a way as to encircle a base layer. CONSTITUTION:So as to suppress small the resistance of a junction FET part, a drain medium-concentration layer 4 having a concentration several-fold higher than a drain low-concentration layer 2 is provided around a base layer 5 by a self-matching using a gate electrode layer 8 as a shielding film. Therefore, with the resistance of the part lowered, the spreading of a depletion layer to the conduction part of the junction FET is inhibited and the resistance can be suppressed small. Moreover, this layer is very thin because being sectioned by a diffusion depth difference only from the base layer 5 by a self-matching and gives little effect to the spreading of a depletion layer at the time of inverse bias and because the concentration does not exceed several times.

Moreover, the microprocessor 12 compares the measured sensor current with an initial sensor current, detects a deterioration degree of a sensor element, and sets a set current value of the circuit CI to be optimum in accordance with the deterioration degree.  The presence/absence of a card C and a position of the card are detected by comparing the voltage Vs with the threshold Vth.

Title: Shock absorbing rubber sheet and its manufacture
Inventor: KATO SHIGEMITSU
IPC: G11B19/20
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction in a reading operation by providing a rubber sheet which is cross-linked by electron beam radiation, superior in sliding resistance, and has a web texture with thickness of 0.1 to 0.4mm, thickness precision of less than 0.01mm and surface roughness of (Rz)=40 to 200μm. SOLUTION: The texture is formed by transferring a desired surface roughness to a rubber sheet. The desired surface roughness in ten point average roughness Rz is 40 to 200μm. If the Rz is less than 40μm, disks such as a CD has a tendency to be stuck. If the Rz exceeds 200μm, the resistance against sliding becomes insufficient. Moreover, if an average interval S of projecting and recessing parts is less than 150μm, the reduction preventive function of the static friction coefficient is disturbed by the roller effect of stuck dust and the sliding resistivity is reduced. If the interval S is more than 600μm, the static friction coefficient is reduced.

Abstract: PURPOSE:To obtain an inexpensive active matrix substrate which uses thin film transistors having sufficiently large ON current, a sufficiently small OFF current and excellent reproducibility and reliability by employing a true polycrystalline silicon thin film on a channel region and a true polycrystalline silicon thermally oxidized film on a gate insulated film. CONSTITUTION:After a true polycrystalline silicon 9 is accumulated on an insulating substrate 8, a thermal oxidation is performed, thereby forming a gate insulated film 12. Then, a gate electrode 13 and a common electrode 17 of a condenser are formed. These two electrodes may be formed of the same conductive material simultaneously. Subsequently, after an impurity is doped to form source and drain regions 10, 11, an interlayer insulated film 14 is accumulated, and a contacting hole is opened. The doping of the impurity to the source and drain regions is performed by thermal diffusion or ion implantation. Subsequently, a gate line 15 is formed, and a drive electrode 16 is then formed to complete it. In this manner, the true polycrystalline silicon thin film is used to increase the ON current in the channel region, and the OFF current is reduced.
