Title: Die bonding material of semiconductor element
Inventor: YOKOZAWA MASAMI
IPC: H01L21/52
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a die-bond material without an element of lead for a semiconductor element, along with good radiation and large adhesive. SOLUTION: Germanium of 0.5 to 5wt.% as a metal hardly reactive to oxidation is added to tin (Sn) of 95 to 99.5wt.%. Then, the die bond material is not deteriorated by oxidization in a heat treatment step, so high adhesive force can be obtained. When bismuth(Bi) or bismuth(Bi) and zinc(Zn) are added to the alloy solder made of tin and germanium, the melting point can be adjusted, and the generation of a brittle intermetallic compound can be prevented. The bonding force between a lead frame and a semiconductor element can be improved.

Title: Heterojunction bipolar transistor
Inventor: KOBAYASHI TORAKICHI
IPC: H01L29/737
Filed: 1988-02-16
Abstract: PURPOSE:To prevent leakage of electric currents which flow between emitter and base layers and reduce the loss of electricity consumption, by providing an external base layer in such a way that its layer is to the side of a collector layer closer than an intrinsic layer, thereby insuring that the contact is made between an intrinsic base and a base electrode metal. CONSTITUTION:A groove 11 for isolating a base which is provided so that its groove passes through the first and second semiconductor layers and an external base 6 which is provided at the groove bottom for isolating the base so that its base comes into contact with the second and third semiconductor layers are equipped. Contact is made between the section of an intrinsic base layer 3 and an electrode metal 7; besides, so as to prevent a short circuit between a collector layer 2 and a base electrode metal 7, a semiconductor layer which has the same conductivity type as that of the intrinsic base layer 3 is formed in such a way that a part which is in contact with the base electrode metal is formed into an external base layer 6. Thus, the base semiconductor metal 7 is connected directly to the intrinsic base layer 3, and yet, it is tightly in contact with the base 3 and only the intrinsic base layer 3 comes into contact with an emitter layer. The base layer is so completely free from confusing leakage of the electric currents that it improves transistor characteristics.

Title: Structure of film winding knob
Inventor: TASAKA HISASHI
IPC: G03B17/04
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To reduce winding noise by setting an reverse rotation preventing pawl at a prescribed position even when the molding accuracy of the reverse rotation preventing pawl is relaxed. SOLUTION: At a main body base part 20, the reverse rotation preventing pawl 40 obtained by integrally molding a positioning arm 45 is formed on the rotation center side of a film wind knob 17. A projection part 41 whose cross-section is circular is formed on the upper surface of the knob 17 coaxially with the rotation center of the knob 17. When the knob 17 is assembled to the upper surface of a cartridge housing chamber 30, the arm 45 is displaced to a position where the tip part 45a thereof abuts on the circumferential surface 41a of the projection part 41 in the direction away from the rotation center side of the knob 17. Consequently, the pawl 40 is displaced in the direction away from the rotation center side of the knob 17 and set at the prescribed position.  When the pawl 40 is positioned, the reverse rotating operation of the knob 17 is obstructed and the engagement amount with the teeth of the knob 17 is reduced. Besides, the arm 45 is brought into slidable contact with the upper surface of the knob 17 so as to prevent the pawl 40 from being vibrated.

Title: Color signal processing circuit of digital color television receiver
Inventor: MAEDA TETSUHIRO
IPC: H04N9/64
Filed: 1989-02-10
Abstract: PURPOSE:To decrease the number of multipliers by using one multiplier for both the color gain adjustment and a tint multiplication in time division. CONSTITUTION:An inputted video signal is sampled with a frequency (4fsc) being 4 times of the chrominance subcarrier frequency (fsc) and becomes a digital video signal and separated from a luminance signal with a Y/C separation circuit 16. A digital chrominance signal is multiplied with a coefficient A1 for color gain control at a multiplier 38, the result is outputted and then coefficients A2, A3 for tint control are multiplied with a chrominance signal C after demodulation and the result is outputted. Since the multiplier 38 for color gain control is used as a multiplier circuit for hue control in time division in this manner, one multiplier is enough for the subject circuit.

Title: Copying device
Inventor: ISHIDA MASAHITO
IPC: G03G15/36
Filed: 1981-03-06
Abstract: PURPOSE:To form an image in the center of a copy paper without correcting the position of an original, by shifting the copy paper feed timing or the like in accordance with key input data. CONSTITUTION:When an advance key 101 is closed, an AND gate Q1 is opened during the timer duration of a timer T1, and an LED 121 is lit through a trasistor TR Q2 by a high-level output passing through a timer T2 interlocked with a return switch 100 and an inverter Q3, and the shortening of the paper feed timing is indicated. Simultaneously, when a high-level output passing through the inverter Q3 is applied through an inverter Q8, a delay circuit A is turned off through a TR Q4. Consequently, when a copy start key is turned on while a LED 120 is lit, a paper feed signal and a resist signal are applied from read switches 31 and 32 to a CPU at a timing quicker than that for the normal copying. The paper feed signal and the resist signal are delayed similarly, and thus, an image is formed in the center of the copying paper without troublesome operations such as correction of the original position.
