Title: Vehicle operation condition recorder
Inventor: OZEKI TADASHI
IPC: G08G1/00
Filed: 1993-03-10
Abstract: PURPOSE:To automatically record data without requiring driver's input work by providing a signpost at a pass or stop point of a vehicle and recording the place name code and the time received there. CONSTITUTION:The place name code of a pass or stop point of the vehicle is transmitted from a transmission part 22 of the signpost provided at this point. When the vehicle approaches the signpost, a reception part 6 attached to the vehicle receives and outputs the place name code transmitted from the signpost. A recording control part 5 records the received place name code and the time on a recording medium when the place name code is received by the reception part 6. It is preferable that the time to be recorded on the recording medium is calibrated by the time added to the place name code transmitted from the signpost. Thus, driver's labor is omitted.

Title: Heat exchanging system for air
Inventor: SAKAI TSUGIO
IPC: F28C3/06
Filed: 1983-03-23
Abstract: PURPOSE:To further enhance the thermal efficiency by making one of two heat exchangers into a direct type heat exchanger in which an intermediate thermal medium directly contacts the passing air. CONSTITUTION:The air with a high enthalpy taken from an inlet 5 is cooled while passing through heat exchanging sections 3, 3, and ultimately leaves from an outlet 7 via a demister 6. The air with a low enthalpy taken from an inlet 14 is heated as it retains nearly saturated humidity condition while it passes alternately through a humidifier 4 and heat exchanging sections 8, 8, and ultimately leaves from an outlet 16 via a demister 15. Both the indirect heat exchanging sections 8 8 are connected to a retrieval basin 30 of the first heat exchanger 1 that takes in a high entalpy, and by forming recirculation circuits 17, 17 containing a sprinkler device 32 and the retrieval basin 30, the recirculation is done between both the heat exchangers 1, 2 by a pump 18 in respective circuits 17. As the first heat exchanger 1 which exchanges heat with a high entalpy air is of a direct contact type in which an intermediate medium is sprinkled into a passing air, the heat exchanging efficiency is high and the performance can be improved.

Title: Manufacture of thin-film circuit
Inventor: GERORUTO BURENTORII
IPC: H01L21/48
Filed: 1990-03-02
Abstract: PURPOSE: To increase the adhesion strength of a Cu conductor path on a ceramic substrate, by selectively forming the substrate having a non-conductor surface of the conductor path by the semi-additive method. CONSTITUTION: After the surface of a substrate 7 is precleaned through plasma treatment, a basic metallic layer 3 which mediates the adhesion of a conductor path to the substrate 7 and is composed of CuCr or NiV is sputtered on the entire surface of the substrate 7. Then, a desired conductor path 6 is formed by strengthening the area 5 of the metallic layer 3 not coated with a photo- lacquer 4 electrically or in a no-current state so as to selectively coat the layer 3. Finally, the non-strengthened part of the layer 3 is etched off. As a result, a metallic layer which has an adhesion resistance to a material is obtained. Therefore, a conductor path structure which excellently adheres even to the surface of a ceramic substrate can be obtained.

Title: Shock absorber control device
Inventor: SUZUKI YUTAKA
IPC: B60G17/015
Filed: 1990-03-01
Abstract: PURPOSE:To improve steering stability by stopping the switching of a damping force characteristic or correcting the standard range of a damping force characteristic switching means and time until returning damping force characteristic when the abnormality of a vehicle speed sensor is detected in a shock absorber control device switching the damping force characteristic according to a road surface condition. CONSTITUTION:The exceeding a standard value of the irregular condition of a road surface, detected with a road surface condition detection means M2, causes the damping force characteristic of a shock absorber M1 to be switched with a damping force characteristic switching means M4. The standard range of the standard value and/or time until returning the damping force characteristic is set by a detected vehicle speed with a standard range-time setting means M5. The detection of the abnormality of a vehicle speed detection means M3 with an abnormality detection means M6 causes an abnormality treating means M7 to stop the switching with the damping force characteristic switching means M4, or to correct a standard range and/or time until returning damping force. This constitution can ensure steering stability even at the time of vehicle speed sensor failure.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and to miniaturize a device by providing a curved part which is formed at a part of a grid plate and elastically deformed and stretched at the time of fitting the grid plate so as to make the grid plate itself keep tension. SOLUTION: A corona electrifier 2 is formed of a front block 40, a rear block 41 both of which made of insulated members and a shield plate 42 regulating an electrical charging area.

Title: Optical head device
Inventor: UCHIYAMA MINEHARU
IPC: G11B7/135
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To simplify the structure and to facilitate the assembling work by constituting an optical head device by converting 1st and 2nd light beams of a 1st polarized light into a luminous flux of a 2nd polarized light, diffracting the converted 1st and 2nd light beams of the 2nd polarized light through a grating lens, and receiving the light transmitted through a simple diffraction grating. SOLUTION: A luminous flux of each spot reflected by an information recording surface of an optical disk passes through an objective 15 reversely, and then, passes through a quarter-wave plate 14, and becomes S-polarized light oscillating in a direction orthogonal to a beam of laser light emitted from a semiconductor laser 11. Since this reflected light is diffracted into diffracted light through a grating lens 13 and is made incident on a simple diffraction grating 10 as P-polarized light, 100% of this reflected light passes through the grating and the main beam is received by a photodetector 17, and two sub-beams are received by photodetectors 18a, 18b.  Thus, it is possible to prevent a C/N of an information signal from a deterioration problem caused by it that the reflected light from the optical disk is diffracted through the simple diffraction grating and received by the photodetector.
