Title: Implantation of ion
Inventor: NOGUCHI TAKASHI
IPC: H01L21/265
Filed: 1989-04-20
Abstract: PURPOSE:To reduce a lattice defect produced in a region between an ion implantation layer and the surface of a substrate even when the ion implantation layer is formed in a deep region of the substrate by a method wherein, while a temperature gradient is being generated in the substrate, ions are implanted into the substrate along a direction from the low-temperature side toward the high-temperature side. CONSTITUTION:An Si wafer 11 as a whole is fixed at a temperature (77 K) of liquid nitrogen or a temperature lower than that; the rear 11a of the Si wafer 11 is irradiated with ultraviolet rays 12 in a pulse manner. Since Si has a large absorption coefficient of the ultraviolet rays 12, the ultraviolet rays 12 are absorbed near the rear 11a; the Si wafer 11 is heated only near the rear 11a; a temperature gradient is generated between the rear and the surface 11b. In a state of a large temperature gradient, ions 13 are implanted into the Si wafer 11 from the side of the surface 11b of the wafer 11 in synchronization with a pulse width of the ultraviolet rays 12. Thereby, a channeling phenomenon is easy to cause in a shallow region and is hard to cause in a deep region of the substrate. Accordingly, even when an ion implantation layer is formed in the deep region of the substrate, a lattice defect produced in a region between the ion implantation layer and the surface of the substrate is reduced.

Title: Mos field-effect transistor and semiconductor device
Inventor: MUTO NOBUHIKO
IPC: H01L29/78
Filed: 1986-04-30
Abstract: PURPOSE:To reduce 1/f noises largely by constituting a channel region of a p-type Si substrate, an (n) buried layer on the p-type substrate and a p-type diffusion layer on the n-buried layer. CONSTITUTION:A channel region 8 isolated by an n source 2, an (n) drain 3 and an element isolation layer 9 is organized of a p-type Si substrate 1, an n-layer 4 buried in approximately lmum depth from the interface with an insulating film 6 and a (p) layer 5 similarly ion-implanted up to 0.3mum from the interface. When the same constant voltage is applied to the source 2, the drain 3, a gate electrode 7 and the substrate 1, the (n) buried layer 4 and the (p) diffusion layer 5 form a p-n junction and a depletion layer is generated, and a conduction channel is not brought into contact with the interface with the insulating film, and is not brought into contact with the interface so far as gate-electrode voltage is not increased until a forward bias higher than self-contained potential is applied to the p-n junction. When a section between the source 2 and the drain 3 is conducted, employing the source 2 as a positive value, the depletion layer is also expanded because carrier density per unit volume in the channel is lowered with an approach to the drain 3, and the conduction channel is withdrawn from the interface. Accordingly, the 1/f noises of the FET are reduced largely.

Title: Automatic water discharging device
Inventor: OHASHI SHIGEKAZU
IPC: A62C27/00
Filed: 1990-04-19
Abstract: PURPOSE:To enable a water discharging quantity to be automatically controlled according to the situation of fire accident by transmitting audio signal and control signal between a nozzle section and a plurality of integrally arranged slave machines, and by setting a master machine for controlling the water discharging quantity of the nozzle section. CONSTITUTION:When water discharging is started from a nozzle, and when the switch OPEN of a slave machine 1 is pushed down, then DTMF signal according to the pushing-down is transmitted to a master machine 40 via two wires. Then, by a DTMF signal detecting circuit 71 in the master machine 40, a confronted control element 83 is turned ON, and so water is discharged from the tip of the nozzle 5. In this case, when a switch UP is once pushed down by a fireman, then a water discharging quantity is one-step-increased step by step. Besides, when a switch DOWN is depressed, then the water discharging quantity is reduced step by step, and when a switch SHUT is pushed down, then the water discharging is stopped. Besides, when conversation is executed on the side of the slave machine by firemen under fire fighting activity, then even if these operating switches are pushed down, a DTMF signal transmitting circuit 61 is set in the state of non-working, and so DTMF signal is not transmitted. Besides, when conversation is executed on the side of the master machine 40, and when the switches of the slave machine are operated again, then the water discharging quantity from the nozzle can be controlled.

Title: Optically functional thin film, its production and light emitting device
Inventor: DEN TORU
IPC: C09K11/54
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To improve the luminance, stability and efficiency by constituting a porous layer mainly composed of Si on a substrate, and dispersing phosphor fine particles in the porous layer. SOLUTION: Although a thin oxide film is frequently formed on a Si wafer surface even by anodization of the Si wafer in an acidic aqueous solution containing no fluorine, fine irregularities are formed on the surface according to the increase in voltage, and an oxide silicone layer with low density is formed. This layer has a porous structure where fine pores are opened in sponge form. To bury a phosphor in this layer, AC electrodeposition is conveniently used to prevent the adhesion of the excessive fine particle or film to the porous film surface. As the phosphor, a material capable of electrodeposition is preferably used, and ZnO:Zn is particularly effective. In order to produce the fluorescent layer thickly, the microporous Si layer is manufactured and then anodized in a solution other than fluoric acid, whereby a porous Si/SiO2 composite structure can be produced.

Patent JP-S61260494-A (JP)
Title: Decoder circuit
Inventor: HASHIMOTO KIYOKAZU
IPC: G11C16/06
Filed: 1985-05-14
Abstract: PURPOSE:To improve a read characteristic by permitting a pulse generating circuit for inputting a control signal for controlling the programming action of a semiconductor memory element to generate a pulse signal. CONSTITUTION:After a program mode is terminated, a speed discharging an electric charge charged to a selected word line X1 in a program mode will not change due to the variance of the threshold of a shallow depression, and therefore the threshold of the shallow depression can be decided only by the read characteristic. Namely, under a drain of 5V, a gate at zero V and a source at zero V, a current ITD2 flowing into a Q16 can be set to valus where a read voltage VR becomes highest. Thus the voltage of the word line selected in a read mode can be set at a high level to accelerate a speed, and the value of a critical VCC acting normally is set at a low level to improve the read characteristic.

Title: Feedforward control type phase locked loop circuit
Inventor: TANIGUCHI YASUHIRO
IPC: H03L7/099
Filed: 1994-04-14
Abstract: PURPOSE:To obtain an output signal that has the frequency synchronous with that of an input signal by providing a voltage control multivibrator oscillator, a frequency comparator and a loop filter. CONSTITUTION:An input pulse is inputted to a phase synchronizing pulse generator 35, and a phase synchronizing pulse of a prescribed width is generated at the rise/fall time point of the input pulse. The phase synchrionizing pulse is inputted to a voltage control oscillator VCM 31 and oscillated there. Thus the output signal of the VCM 31 has the phase synchronization with the input pulse in a remaining time base error 0. Then a stabilizing circuit 37 limits the control voltage change range that is outputted from a frequency comparator 27 and inputted to the VCM 31 via a loop filter 29 to a proper level of range. Thus the circuit 37 limits the oscillation frequency range of the VCM 31 and stabilizes the VCM 31. As a result, the proper phase synchronization is attained even with use of a multivibrator as a voltage control oscillator. Thus it is not required to heighten the oscillator frequency.
