Title: Provision of solar heat "pechka"
Inventor: TANAKA MAKOTO
IPC: F24S90/00
Filed: 1980-02-29
Abstract: PURPOSE: To convert the solar energy into the heat source of room heating effectively by a method wherein metallic plates, one side thereof is painted black and the rear surface thereof is made into glittering white color, are provided in adaptor holes provided on the wall of a house so as to face the black side toward outside of the house.  
     CONSTITUTION: The stainless steel plate, the one side surface thereof is black and the other surface thereof is glittering white, has a large effect for the one way trafic of radiant heat. An energy accumulated in a room and the solar energy projected against the black surface directly are emitted into the room immediately because of the glittering white color of the back surface. Even when the outdoor temperature is reduced in winter, the warm air in the room will not be released to the outside of the room because of the glittering white color. The solar energy, which is considered to be of infinity, may be utilized effectively in 100% as the heat source for the room heating or the "pechka". Such method has a merit wherein the warm air in the warm room is released into the room immediately, moreover, emission of the warm air in the room to the outside thereof can be insulated. According to this method, the solar energy may be converted into the heat source for the room heating effectively.

Abstract: PURPOSE:To reduce the number of arithmetic circuits required for erasure correction and to simplify a hardware, by simplifying the item of a numerator in an arithmetic equation for finding an error vector by using a product sum operation. CONSTITUTION:By performing the product sum operation on syndrome Snu(nu=0-n-1) and error location Xj(j=1-n) in order by using the following rule, and setting an i-th answer as Snu,i, S0, n-1 can be obtained. Namely, Snu,i =Snu,i-1Xi+Snu+1, i-1, (1<=i<=n-1), where, it is (Snu, 0=Snu). Next, the error vector Yn is obtained based on equation by using the S0, n-1, then, error correction is applied. It is possible to simplify the item of the numerator in the arithmetic equation in a case where the error vector Yn is found, and to reduce the number of times of the arithmetic operation in the erasure correction, In such a case, a processing to simplify the item of the numerator can be performed by repeating the product sum operation, thereby, it is possible to simplify the hardware.

Title: Deciding system for binary data
Inventor: FURUKAWA TERUO
IPC: G11B20/18
Filed: 1989-02-03
Abstract: PURPOSE:To establish the system of decision of 4/11 code or k/n code in the process of decoding by sampling an analog signal at a prescribed period, applying A/D conversion to the result, deciding an n-bit code while making the digit of high-order k-set samples significant and comparing the code with a predetermined erasure code. CONSTITUTION:When an analog signal AS is inputted, the signal is converted by an A/D converter 4 according to a clock signal CLK and the converted digital signal is inputted to a decision circuit 5. Then the decision circuit 5 latches the result at each period of the clock signal CLK and a digit with a maximum value is stored. Then the decision circuit 6 of the next stage stores the 2nd digit of the 2nd priority. Similarly, decision circuits 7-9 store 3rd-5th digits respectively. Thus, the decision circuits 5-8 output a 11-bit code to an OR circuit 11. Since it is not an erasure code, the output of an erasure code decision circuit 12 represents the normal state and when the output of the OR circuit 11 is fetched in a proper timing, a correct 4/11 code is obtained.

Title: Small-signal transistor for surface-mounting use
Inventor: ADACHI MASAKI
IPC: H01L21/60
Filed: 1989-02-06
Abstract: PURPOSE:To prevent a deformation and a disconnection of a bonding wire and to enhance reliability by a method wherein a resin is caused to flow along a longitudinal direction of the bonding wire and it is filled into a cavity seals the same. CONSTITUTION:Bonding wires 13a, 14a are arranged in such a way that their longitudinal direction is nearly parallel to side walls 21a, 22a of a cavity A; they are arranged nearly in a row; they are parallel also to an inflow direction 23a of a molten sealing resin flowing into the cavity. Accordingly, when the resin flows nearly perpendicularly into the cavity A via a gate opening part 17a from a wall face of an end wall 16a of the cavity A, a flow direction, inside the cavity, of the sealing region nearly coincides with a wiring direction of the bonding wires 13a, 14a. As a result, a resistance between the sealing resin and the bonding wires 13a, 14a during a sealing process is reduced sharply. Thereby, even when a thermoplastic resin is injected at high speed, the bonding wires 13a, 14a are not disconnected; reliability and yield are enhanced.

Title: Method for measuring oh concentration using laser-induced fluorescence method
Inventor: DEGUCHI YOSHIHIRO
IPC: G01N21/64
Filed: 1994-01-31
Abstract: PURPOSE:To measure the OH concentration in a measuring field higher than the atmospheric pressure with high accuracy by matching the wavelength of a laser beam to the absorption band characteristic to OH at the time of starting measurement. CONSTITUTION:At the time of making a laser beam 3 incident to a measuring field 5 higher than the atmospheric pressure, the wavelength of the laser beam is matched to the (2, 0)-band 260-270mm) or (2, 1)-band (280-290mm) of the absorption bands of OH so that the OH concentration in the measuring field can be measured by detecting fluorescence generated by the laser beam. In the bands 260-270mm and 280-290mm, overlapping of absorption lines does not occur, because absorption lines of other molecules, such as O2, etc., scarcely exist. When the field 5 is irradiated with the laser beam 3, the intensity of the beam 3 is little damped, because the quantity of background fluorescence is small and the beam 3 is not absorbed much.
