Title: Hetero junction type bipolar transistor
Inventor: KAWAI HIROHARU
IPC: H01L29/72
Filed: 1987-05-11
Abstract: PURPOSE:To obtain a hetero junction type bipolar transistor which has excellent high rapidity and an easy integration by bringing an intrinsic base region into contact with an external base region at one side, and reducing the width of the intrinsic region smaller than that of the external region. CONSTITUTION:An external base region 36b is formed in contact with an emitter region 33E at the side face of one side, and a barrier layer 32 made of semi- insulating AlGaAs is formed under the regions 36b, 33E. Intrinsic base region 38B and collector region 39C having a width W2 smaller than that W3 of the external base and that W1 of the emitter region are formed on the part of the region 33E so as to include a boundary between the regions 33E and 36b, i.e., to bring partly into contact with the region 36b. Thus, a collector capacity and an emitter capacity are reduced, and a hetero junction type bipolar transistor in which a resistance is reduced in the base contact, with excellent rapidity and easy integration is obtained.

Title: Connecting rod of internal combustion engine
Inventor: SATO YASUNORI
IPC: F16C33/14
Filed: 1993-04-16
Abstract: PURPOSE:To facilitate light weight and manufacture and improve the qualities of anti-wear and anti-fusing together by providing sliding surface portions where only a cap at a large end portion slides directly with the shoulder surfaces of a crank shaft. CONSTITUTION:A large end portion 8 consists of a main body portion 8a and a cap 8b of a C shaped separate body consisting of a titanium alloy, and is fitted and fixed at a crank pin by means of a bolt and a nut. The cap 8b is a little thicker than the main body portion 8a, and sliding surface 12, 13 alone at both ends of the cap 8b are possible to slide with the shoulder surfaces 14, 15 of a crank shaft, and a hand film 17 consisting of titanium nitride is formed on the surface 16a of the base material 16 of the cap 8b by means of an ion plating method. Accordingly, to conduct at the cap 8b alone surface processing for improving the qualities of anti-wear and anti-fusing together is sufficient, and so the number of works is reduced and the cost of manufacturing is decreased. In the case of forming the cap 8b alone out of a ferrous alloy, there is no need of the hard film, and the number of the works of connecting rod manufacture can be reduced further, and there is no chance of becoming weighty.

Title: Catalyst block transfer equipment
Inventor: MASUTOMI HIROSHI
IPC: B01D53/94
Filed: 1978-09-19
Abstract: PURPOSE: To facilitate the transportation and arrangement of large size, heavy weight catalytic layer blocks so as to fully develop their inherent catalytic function.  
     CONSTITUTION: The block suspender 17 transfers a catalyst block 7 from the hatch 13 into the duct D. The truck 8 is easy to move by a worker pulling the rope because the bottom of the block 7 is located above the top face 14' of the catalyst support beam 14. When the block 7 is reached to the desired position, the table 7 is gradually lowered, so that the block 7 is mounted on the catalyst support beam 14, making space between the face of the table 9 and the bottom of the block 7. This makes the truck 8 free to move, which is then moved back to the original position to hang up the block 7, by the rope 11 at the opposite side. The process is repeated to form catalyst layers, through which waste gas G passes for its nitrification to be performed.

Filed: 1981-07-21
Abstract: PURPOSE:To prolong the life of a battery, by switching a driving pulse of the highest rank to that of lower rank, from the following step, if non-rotation of a rotor is detected when the driving pulse for driving a step-motor is in the highest rank. CONSTITUTION:When a battery whose initial voltage is high is turned on, a regular driving pulse of duty 14/16 is applied to a coil 31 of a step-motor from a driving circuit 30 of the step-motor, a rotor 32 is rotated normally, but since its driving force is too strong, an induced voltage detecting circuit 33 decides that the rotor 32 has been in non-rotation.  Therefore, a correcting pulse passes through selecting gates 20, 21 and is applied to the driving circuit 30. In this case, the uppermost digit of an up-and-down counter 40 is reset, and in the following step, a regular driving pulse of duty 11/16, whose driving force is lower by 3 ranks is outputted from the selecting gates 20, 21, and by this signal, the rotor 32 is driven.

Inventor: IWAKI MASAMITSU
IPC: F25D11/02
Filed: 1995-05-12
Abstract: PURPOSE: To shorten a period of time for the returning to specified temperatures of a freezer chamber and refrigerator chamber by a method wherein when a defrosting completion-detecting means detects a temperature which is a set temperature or higher at the time of turning-on of the power, the operation of a blowing fan is stopped for a previously set period of time only when the defrosting completion-detecting means detects a condensation temperature sensor upper limit set temperature or higher after a specified period of time has passed. CONSTITUTION: When a detected temperature of a defrosting completion-detecting means 9 right after the start of operations of a compressor 4 and blowing fan 7 is a set value or higher at the time of turning on of a power source, i.e., when it is detected that the outside air temperature is high, and a cooling is not done yet, a judgement whether a detected temperature of a condenser temperature sensor 24 is an upper limit set value or higher or not is performed after a specified period of time has passed after the detection. Then, when the detected temperature is the upper limit set value or higher, i.e., under a state wherein an input load to the compressor is too large, power is prevented from being connected to the blowing fan 7, and the blowing fan is made to stand by until a previously set period of time passes.  Then, after the specified period of time has passed, the power connection to the blowing fan 7 is resumed, and the control is transferred to a normal control routine.

Title: Paper feeder
Inventor: SHINO SATOSHI
IPC: B65H3/68
Filed: 1984-06-06
Abstract: PURPOSE:To prevent the occurrence of troubles such as misfeed, bending of paper and a paper jam by providing movable guide means for regulating the curved shape of a sheet caused by stopping the leading edge of the sheet, which is inclined upward to retreat according to the elastic restoring force and advancing force of the sheet. CONSTITUTION:A paper feed roll 7 is rotated to take out a sheet P1. While the leading end of the sheet is passed through a path B abd brought into contact with an intercepting member 20 to keep the sheet from advancing, so that the sheet is stopped, the trailing end of the sheet is continuously carried out. Accordingly, the sheet P1 is curved by buckling, and separated from a guide plate 17 to be lifted upward and brought into contact with ribs 14 of a guide plate 13. When the intercepting member 20 is retreated in synchronization with rotation of a photosensitive drum in such a condition, the sheet P is forced to rush between transport rolls 19 by its elastic restoring force and fed to a transfer position. As the lower surface of the guide plate 13 is provided with a plurality of ribes 14, the curved shape of the waiting sheet P1 is properly regulated, so that the sheet is fed reliably and smoothly without troubles.

Filed: 1991-05-20
Abstract: PURPOSE:To suppress such a key operation as to damage a keyboard by warning that an operator is in an excessively excited state in accordance with the mental state of the operator decided based on the detected pressure. CONSTITUTION:The emotion of the operator can be always checked by attaching piezoelectric elements 13 to the keyboard plate 12 under all or a fiew key tops 11 of high frequency in use above the keyboard plate 12 and measuring the pressure of the push-down of a key. Accordingly, by delaying in stages the execution of service the operator requests, he can be informed earlier that he is in the excessively excited state, and since the operator becomes cool spontaneously or he is compelled to change the feeling after interrupting spontaneously the request of the service to a computer, it becomes effective warning. Thus, such the key operation as to damage the keyboard can be suppressed.
