Patent JP-H0324817-A (JP)
Title: Analog switch
Inventor: KUROKAMI HIROAKI
IPC: H03K17/60
Filed: 1989-06-21
Abstract: PURPOSE:To surely keep an output terminal in the turning-off state by using first and second transistors TRs whose output terminals are mutually connected in series, and connecting resistances between the intermediate connection point of these TRs and input terminals of bases. CONSTITUTION:A leak current I5 of the reverse bias of the base-collector junction of a first TR Q1 is generated from a collector C1 of the first TR Q1 to a base B1 by the voltage applied to an output terminal A. Resistances R8 and R9 are connected between the base and the emitter of the first TR Q1. Consequently, the leak current 16 is by-passed to resistances R8 and R9 and does not flow between the base and the emitter of the first TR Q1 when the resultant resistance value of these resistances is properly set. Thus, since the first TR Q1 is kept in the complete cut-off state, the circuit between an output terminal A and an earth terminal G is kept in the turning-off state independently of the state of a second TR Q2.

Inventor: YUASA NAOKI
IPC: H04L12/54
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To distribute a load of a server distributing information and to distribute the information efficiently to the user. SOLUTION: A terminal 1 requests music data and information of a desired time of data distribution to a distribution server 2 through a communication channel 3. The distribution server 2 decides a scheduled distribution time depending on the past distribution result and a state of a transmission line based on the desired distribution time from the terminal 1 and sends the decision to the terminal 1. A timer sets the terminal 1 to be in a standby state till the scheduled distribution time comes. When the scheduled distribution time comes, the timer automatically starts the terminal 1, which is set to a distribution waiting state. Then the distribution server 2 distributes the requested music data via a satellite 100. The terminal 1 receives the distributed music data. When reception of data is finished, a power supply of the terminal 1 is turned off.

Title: Flame tomographic measuring method
Inventor: KATO FUMIO
IPC: G01N21/64
Filed: 1989-06-23
Abstract: PURPOSE:To image and measure the density values of plural components of an intermediate product produced in an elementary reaction process of combustion instantaneously at the same time by synthesizing laser light beams which match the absorption spectrum wavelength of a body to measured together, putting the light beams into a sheet shape and irradiating the body to be measured with the light beams. CONSTITUTION:The laser light beams from dye lasers 12 and 13 are tuned and mixed through a mirror 14, a dichroic mirror 15, a cylindrical lens system 16 and a beam splitter 17 so as to match absorption spectra of plural materials to be measured at the same time, and then the beams are changed from circular section to sheet section, and the body to be measured is irradiated with the beams. Consequently, materials in the section absorb light energy to rise in energy potential from base states to excited states and then return to the original base states in short times to emit fluorescent light. The fluorescent light is observed on a lower-wavelength side than the absorption spectrum wavelength. Those two kinds of the fluorescent light are observed by a high-sensitivity camera device 24 arranged at right angles to the tomographic surface. The fluorescent light beams are separated by an optical filter 18, so simultaneous video formation becomes possible.

Filed: 1987-06-29
Abstract: PURPOSE:To improve the reproducibility and yield of film formation by correcting the ripple shape in successive transmission bands to increase transmittance and confining a central wavelength value within a prescribed range. CONSTITUTION:A substrate which is a dummy is previously housed in a vapor deposition device and a band-pass filter (BPF) having 35-37 layers and 5 cavities is formed. Spectral characteristics are measured upon ending of vapor deposition. The shape and central wavelength of the ripples in the pass band are noticed and the spectral characteristics thereof are decided. Judgement can be made as to how much the film thicknesses of the high-refractive index materials H and low-refractive index materials L of the respective layers are increased or decreased in order to obtain the BPF having the desired ripple shape and central wavelength. The optimum conditions including the film thickness control method for obtaining the BPF having the desired ripple shape and central wavelength are easily obtainable if vapor deposition is executed successively several times. The BPFs satisfying the prescribed standard values are easily obtd. continuously with the good reproducibility if the vapor deposition is thereafter executed under said conditions. The yield is thus improved.

Abstract: PURPOSE:To make a whole operation valve unit compact in its size by arranging coaxially valves of vacuum preventing units for opening and closing communicating holes and valves of check units for checking the flow to the entrance port sides of oil holes. CONSTITUTION:The first and second communicating holes 12, 13 and the first and second valve holes 14, 15 are bored coaxially in a valve body, and valves 16 for check units are inserted into the first and second valve holes 14, 15.

Abstract: PROBLEM TO BE SOLVED: To avoid a minute defect on a base material from affecting on development of a void region, by growing a light-doped crystal layer on a heavy-doped semiconductor substrate to form an impurity layer, and forming a void region under it so that an insulating layer is formed between the base material and the crystal layer. SOLUTION: On an n<+> type silicon base material 20 wherein, comprising an impurity Sb/As, an electric resistance factor is 0.008-0.02 ohm-cm, an n<+> type first crystal layer wherein, being doped with phosphorus, an electric resistance factor is 0.02-6 ohm-cm is grown, a second crystal layer wherein, doped with V-group element, an impurity concentration is lower than that with an electric resistance factor 6-100 ohm-cm is grown over it, and a p<+> type impurity layer where III-group element is thermally diffused is formed over it. Since an n-type second crystal layer and a p<+> type impurity layer 24 provide a pn junction and an impurity concentration of the n-type second crystal layer is low, most void regions appear in it. As the n<+> -type first crystal layer is an insulating layer, it prevents a minute defect from affecting on the void region.
