Title: Array type infrared detector
Inventor: AJISAWA AKIRA
IPC: H01L27/146
Filed: 1991-02-22
Abstract: PURPOSE:To obtain a high resolution detector comprising a large number of pixels by suppressing crosstalk between pixels. CONSTITUTION:An element isolating groove 7 is provided between photodiodes 6 formed on a p-Hg0.8Cd0.2Te layer 4. Moreover, a gate electrode 10 is formed via an insulating film 8. Since electrons generated in the p-Hg0.8Cd0.2Te layer 4 cannot pass through the element isolating groove 7, crosstalk can be suppressed through correspondence between the incident position of infrared beam and pixel on the one to one basis. Moreover, generation of recoupling current in the vicinity of groove can be suppressed by applying a voltage to a gate electrode 10 so that the periphery of groove is set to the accumulating condition and thereby generated electrons can be guided to the photodiode 6 effectively.

Title: Production of offset curved surface data
Inventor: SASAKI NOBUO
IPC: B23Q15/00
Filed: 1987-03-05
Abstract: PURPOSE:To prevent the excessive cut-off of a processing curved surface due to the blade edge of a tool by interpolating a 2nd tubular offset curved surface and a 3rd offset curved surface for a corner part or a boundary curve that produces a discontinuous space. CONSTITUTION:When a tool moves over a boundary curve that does not satisfy the conditions for continuation of connected planes or a sharp corner part, a 2nd offset curved surfaces COFF12, COFF23 and COFF31 and a 3rd offset curved surface DOFF23 are interplated so that the connection is secured to a 1st offset curved surfaces SOFF1-SOFF3 set opposite to patches S(u,v)1.S(u,v)3 respectively. Thus it is possible to ensure the control so that the tool can pass through a tool route on an offset curved surface formed by said 1st-3rd offset curved surfaces (SOFF1-SOFF3), (COFF12, COFF23, COFF31), (DOFF123). As a result, a cutting process is carried out without cutting off excessively a free curved surface serving as the cutting target when a machine tool is used for cutting.

Title: Control of fermentation
Inventor: OZAWA KAZUMI
IPC: C12R1/46
Filed: 1979-04-27
Abstract: PURPOSE: To effect the precise control of fermentation for forming an acid, e.g. lactic or acetic acid, with multiplied lactic acid bacteria in a medium comprising milk or in combination with sugars, by determining pH as a control index accurately.  
     CONSTITUTION: The pH of the fermentation liquid is intermittently measured by a pH meter comprising a reference electrode whose internal pressure (P) is kept higher than the internal pressure (p) of the fermenter, and the fermentation process is controlled on the basis of the indicated value. A gas having a higher pressure P than p is sealed up in the pressurizing gas holder 11 of the electrode. The internal pressure of the support tube 9 is kept at P by the inlet hole 10 of the pressurizing gas, and the differential pressure between P and p provides the slow outflow of the internal liquid, e.g. KCl solution, by portions. Thus, the poor indication due to the sticking of protein coagulated with the acid is prevented, and accurate pH values can be obtained continually.

Abstract: PURPOSE:To prevent the deterioration of the balancing condition of the hybrid circuit by inserting the first spurious line circuit to be approximate to the impedance of a two-wire system telephone line between the connecting terminal, in which the two-wire system telephone set is connected, and the hybrid circuit, and inserting the second spurious line circuit between the hybrid circuit and the balance circuit. CONSTITUTION:Between telephone set connecting terminals T1 and T2, and a hybrid circuit 11, the first spurious circuit 16 is inserted. When the telephone set connecting terminals T1 and T2 sides are viewed from the hybrid circuit 21 of a telephone set 2, the hybrid circuit 11, the second spurious line circuit 17 and a balance circuit 12 are viewed through the spurious line circuit 16 and in among of them, the impedance of the spurious line circuit 16 dominantly functions. Namely, what is approximate to the impedance of a telephone line 3 can be viewed from the telephone set 2 and the telephone set 2 goes to be almost equivalent to the time when the set is directly connected to the two-wire system telephone line. Consequently, the balance condition of the hybrid circuit 21 in the telephone set 2 goes to be satisfactory and for this reason, the turning to the receiver 23 of the transmitting signal is very little.

IPC: G02F1/355
Filed: 1987-03-06
Abstract: PURPOSE:To increase a nonlinear optical constant without having a loss by doping fine particles of a specific semiconductor, metal or metal oxide as a nonlinear optical medium to the core of an optical fiber. CONSTITUTION:The fine particles of such semiconductor, metal or metal oxide with which one photon transition does not take place at the wavelength of the light to be used and the multiphoton process of >=2 photons takes place near a band gap energy value or takes place near an exciton absorption energy value are doped in the core of the optical fiber. Since the absorption level by one photon process does not exist, the emphasis of the nonlinear optical constant by the two photon process is realized without receiving an excess loss in the fiber. The nonlinear optical constant is thereby increased without increasing the loss by linear absorption in the wavelength region of the light to be used.
