Title: Mounting substrate and method for mounting circuit parts using the same
Inventor: AGAWA KIYOSHI
IPC: H05K1/03
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a mounting substrate which can contribute to the preservation of the global environment and the reduction of the manufacturing cost, by realizing resource conservation and the simplification of the manufacturing process through the effective utilization, etc., of the components of the substrate. SOLUTION: A printed wiring board 10 is manufactured by forming a conductive film pattern 2p composed of Cu foil having a thickness of about 35 μm on one main surface of a sintered molded resin board 1 which is formed as an insulating board by using an organic sintered body of a polyethylene having a thickness of 1.6 mm. Since the density of the resin board 1 is about 1/2 as small as that of the conventional wiring board composed of a molded body of a phenol resin, the weight of the wiring board 10 and the used amount of the material can be reduced. In addition, the wiring board 10 has a sintered structure in which an infinite number of straw-like pores are opened in the thickness direction, no outer lead inserting hole is required at the time of inserting the outer leads 21 of circuit parts 20 into the resin board 1.  Therefore, such a simultaneous process for hole making/inserting that the outer leads are inserted while the holes are made can be used.

Filed: 1983-03-30
Abstract: PURPOSE:To decrease the thermal stress acting on the joint part of solder and to improve reliability by fine adjustment at the top end of an optical fiber by using two kinds of pipes having specific properties to a pipe for holding the optical fiber, and adhering the same to the optical fiber by means of the solder. CONSTITUTION:A holding pipe 8 which is supported by a protective body 3 and a stainless steel pipe 9 and holds an optical fiber 5 is constituted by binding integrally a pipe 8a consisting of an insulator material having the same coefft. of linear expansion as that of the fiber 5, for example, ''Pyrex'' glass and a pipe 8b consisting of a conductive material that can be likewise plastically deformed, for example, ''Kovar'' of ''Fernico'' by anodic bonding 10 to one body. The fiber 5 and the pipe 8a is coupled by solder 11. The thermal stress acting on the joint part of the solder 11 is thus decreased and the fine adjustment in the top end part 5a of the fiber 5 is made possible by the fiber 8b and therefore the change in the light output of the fiber 5 is prevented.

Title: Ignition distributor for internal-combustion engine
Inventor: MORISHIMA HIDEKI
IPC: F02P5/06
Filed: 1984-03-19
Abstract: PURPOSE:To reduce the relative inclination of a signal generating part due to the vibration of a signal rotor shaft by suppressing the axial movement of a bearing which fixes a supporting member of a signal generating part, to a part between the end face of a signal rotor and a centrifugal angle-of-lead mechanism constituting member provided on said signal rotor shaft. CONSTITUTION:The rotation of an internal-combustion engine is transmitted to a distributor shaft 8, causing a signal rotor 1 to rotate. A bearing 3 is free to rotate with respect to a signal-rotor shaft 2, but is stopped to rotate with respect to a housing 9 by means of an operating rod 7. Therefore, a bracket 4 is also stopped to rotate with respect to the housing 9, and the rotor 1 rotates inside the inner periphery of the bracket 4. And, when the projection of the rotor 1 is opposite to the bracket 4, a closed magnetic circuit is formed, generating a signal from an electricity generating coil 10 in accordance with the rotation of the rotor 1. The bearing 3 made of sintered metal, reduces wear of both the bearing 3 and the rotor 1, while a washer 14 placed between the bearing 3 and a collar part 2a improves the durability of the collar part 2a.

Title: Object detector
Inventor: KOMATSU SATORU
IPC: G01S15/04
Filed: 1989-03-06
Abstract: PURPOSE:To enable recognition of a shape of an object accurately and with a high identifiability from a short range to a relative long range by generating a histogram of a amplitude distribution from a reception signal of a pulse type reflected wave. CONSTITUTION:A transmission wave TW by a pulse signal with a fixed width is radiated into the air from a transmitter 1 and reflected wave RW from an object O is received 2 to determine a data of a histogram of an amplitude distribution of the reception signal thereof with a waveform processing circuit 3. The data is compared sequentially with a data of a histogram of several types of objects with known shapes registered in a sample data memory 4 to judge 5 the shape of the object by the coincidence between the data, which enables easy and accurate recognition of the shape of the object O. It also should be noted that this apparatus does not recognize the shape of the object O directly from a waveform characteristic of the reception signal. This eliminates the need for narrowing the transmission wave TW to make the waveform characteristic noticeable and thus, when an ultrasonic type is used as the transmitter 1 and a receiver 2, the shape of a distant object can be recognized even in the air in the order of several m to 10 and several m.

Title: Protection device for refrigerating machine
Inventor: NISHIMOTO KAZUMI
IPC: F25B1/00
Filed: 1995-03-14
Abstract: PURPOSE: To prevent generation of fatal troubles from occurring to a refrigerating machine due to an operational failure of a fan motor for a condenser by detecting a change in a load current of the condenser fan motor, and displaying the trouble with a display means. CONSTITUTION: When a condenser fan motor starts, the rotary speed of the motor rises, since the motor torque is larger than a load torque of the fan and keeps an equilibrium at the point when the motor torque and the load torque are equal to each other, and turns to a low rotary speed. At that time, the load current of the fan motor 4 turns to a steady electric current but when the motor falls into a state different from a regular operating state due to such troubles as shortage of a lubricant at a bearing of the fan motor 4 and damages of the fan, the load current of the fan motor 4 is changed. To comply with this, a control device 1 is arranged to check so as to see whether or not a load current detected by a load current detection means 5 stays in a setting range.  In the case when a failure is detected in the load current, a timer is operated so that the operational failure time may be estimated. When it exceeds the set time, the trouble is displayed by a display means 6, thereby calling for inspection and maintenance.
