Title: Semiconductor device
Inventor: HORIGUCHI SHINJI
IPC: G11C29/04
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To enhance the utilization factor of memory cells by storing don't-care values in address comparing circuits of a defect relieving circuit to make a circuit cope with defects elaborately and to reduce the number of memory cells to be replaced. SOLUTION: Spare memory cells are arranged in areas 120 to 123 and 2L×NB of spare memory cells are arranged at intersections of spare word lines SW and two bit lines NB. At the time of relieving a defect, a memory mat to be selected is decided by comparing row addresses Ax in the address comparing circuits AC of a defect relieving circuit 500. At this time, this circuit copes with various faults elaborately in a one bit unit, one bit line unit or one pair of bit lines unit or the like and the replacing of memory cells is made possible by making compared results coincident regardless of input addresses while storing don't-care values (x) in the address comparing circuits AC.  Thus, the number of memory cells to be replaced is remarkably reduced, the probability of defective memory cells is lowered and also the yield of the memory is enhanced and, thus, an efficient defect relieving circuit is obtained.

Title: Detection of distance to light source
Inventor: YAMAMOTO HIDEKAZU
IPC: G01S11/00
Filed: 1987-12-25
Abstract: PURPOSE:To detect the distance to a light source placed at an arbitrary point with a specific expression by preliminarily measuring overall photocurrents flowing to a semiconductor position detector at the time of placing the light source at two points to which distances from the detector are known. CONSTITUTION:Light sources 8a, 8b, and 8z exist at points A, B, and Z to which distances from a semiconductor position detector 1 are known values (a) and (b) and an arbitrary value (z) respectively. Irradiating light beams 9a and 9b are emitted from light sources 8a and 8b to measure overall photocurrents Ia and Ib flowing to the detector 1. An overall photocurrent IL=Ix+Iy flowing to the detector 1 is proportional to the distance to the light source independently of the incidence position of the light source if the intensity of light of the light source is fixed, and this property is used. Thus, an overall photocurrent Iz flowing to the detector 1 is measured by a light beam 9z project ed from the light source 8z to obtain the value (z) in accordance with z={(aI 2-bIa)/(Ib-Ia)}-{(a-b)/(Ib-Ia)}Iz.

Abstract: PURPOSE:To eliminate invasion or leakage of an electromagnetic wave by covering a part passing a housing of a structure with a shielding cover tube made of a material having excellent conductivity. CONSTITUTION:A through part 2a of a wall 1 of a water supply tube or a drain tube 2 is formed of a nonmetallic tube such as a vinyl chloride tube, etc. Thus, an outdoor side extension 2b of the end is formed of a metal tube or a nonmetallic tube such as a vinyl chloride tube, etc. The outer periphery of the part 2a of the tube 2 is covered with a shielding cover tube 7 made of a material having excellent conductivity, and the tube 7 is further electrically connected by welding or bolt-clamping to an electromagnetic wave shielding plate 3. An external protruding length L of the tube 7 covering the part 2a of the tube 2 from the plate 3 is set to at least four times as large as the inner diameter D of the tube 7. Thus, an electromagnetic wave is attenuated on the way, and cannot pass.

Abstract: PURPOSE:To stably operate a semiconductor element to be contained without erroneous operation for a long period by providing on the upper surface of an insulating base a metallized metal layer, and securing an external lead terminal onto the layer through a special glass member. CONSTITUTION:An external lead terminal 5 is secured onto an insulating base 1 covered on its upper part with a metallized metal layer 4, a glass member 6 secures the terminal 5 onto the base 1 and is operated as a dielectric material of a capacity element A.

Title: Method and device for encoding and decoding picture and picture recording medium
Inventor: KATO MOTOKI
IPC: H04N19/177
Filed: 1992-12-14
Abstract: PURPOSE:To allow the picture decoding side to recognize whether random access to a picture unit is possible or not by adding a flag indicating whether encoding is executed by using a decoded picture belonging to a past picture unit or not to a header at the time of encoding a forward forecasting encoding picture belonging to a prescribed picture unit. CONSTITUTION:When a picture unit (GOP) start instruction signal S10 is inputted from the terminal 21 of a picture encoding device, a random access enabled instruction flag S9 indicating that the encoding does not use a decoded picture belonging to a past GOP is switched by a switch 23 and inputted to a variable length encoder 19. The encoder 19 encodes the input together with an encoding signal S4 or the like and outputs a bit stream. In a decoding device, a GOP header detector 37 checks a flag S26 corresponding to a flag S9 added to a GOP header. Consequently the validity/invalidity of random access can be judged from the flag 26, and in the case of invalid, the retrieval of a random access enabled GOP which is most close timewisely to the specified GOP is continued.

Title: Inverter unit
Inventor: SHIMIZU MOTOHISA
IPC: H02M1/08
Filed: 1990-11-30
Abstract: PURPOSE:To suppress disturbance of FET driving signal immediately after stop of operation by discharging a low frequency component cut-off capacitor through a diode connected in parallel upon provision of an operation stop instruction to a switching device while furthermore discharging a demodulation capacitor. CONSTITUTION:Upon detection of rotational speed drop of engine, engine halt or a state requiring protection, e.g. overload, output of a NOR circuit 702 goes Low while output of an inverter 703 goes High. Consequently, a transistor Q13 is conducted and the light emitting element in each photocoupler PC emits light. Consequently, light receiving elements in four corresponding photocouplers PC are turned ON thus discharging a capacitor 6 and capacitors corresponding to FETs Q6-8 simultaneously. As a result, the voltage to be applied between the gate and the source of each of FETs Q4-Q8 goes zero thus avoiding simultaneous turn ON of the FETs.
